[0175] Detailed description
[0177] In the following detailed description, reference is made to the accompanying drawings, which form a part thereof, and which show, by way of illustration, embodiments in which the disclosure may be practiced. In this regard, directional terminology, such as "top", "bottom", "front", "back", "main", "back", etc., is used in reference to the orientation of the figure (s) ) described (n). Since the components of the figures can be placed in several different orientations, the directional terminology is used for illustrative purposes and is in no way limiting. It should be understood that other embodiments can be used and that structural or logical changes can be made without departing from the scope of the present invention. Therefore, the following detailed description is not to be taken in a restrictive sense, and the scope of the present invention is defined by the appended claims.
[0178] It should be understood that other embodiments can be used and that mechanical changes can be made without departing from the spirit and scope of the present disclosure. Accordingly, the following detailed description should not be taken in a limiting sense.
[0180] It is also to be understood that the phrases "at least one of A and B", "at least one of A or B" and the like are to be understood as "only A, only B, or both A and B".
[0182] Examples of prior art emitters are shown in FIGS. 1-4. An example of a prior art emitter 20a is shown in FIG. 2 and emitter 20a is shown operatively attached to a hose or tape to form an irrigation hose or tape 20 in FIG. 1. An inner surface 21a of a wall 21 of the hose and the outer surface of the emitter 20a form the flow path of the hose or tape 20b. The emitter 20a may be part of a continuous elastomeric tape element 30 that includes a plurality of emitters 20a, and each emitter includes an inlet section 40, a pressure reducing section 60, an optional pressure sensitive section 70, and an outlet section 80, which with a portion of the hose form the flow path of the emitter. Portions of two inlet sections 40a and 40b are shown in Figure 2. The portion of the hose proximate the outlet section 80 includes outlet ports 90 for dispensing out of the hose. This example is disclosed in US Patent 6,736,337, which is incorporated herein by reference. Another example of prior art emitters uses non-elastic strip elements.
[0184] Another example of a prior art emitter 22 is shown in cross-sectional view in FIG. 3 and emitter 22 is shown operatively attached to a hose or tape 26 in FIG. 4. FIG. 4 shows the lamination of the emitter 22, through the rails 25, in an inner wall 26a of the hose 26, thus forming the hose or irrigation tape 10. The inner wall 26a and the emitter 22 form the flow path of the hose or tape 11 through hose 10. A continuous tape element 27, including a plurality of emitters 22, is laminated to hose 26 in a similar manner to the lamination process known in the prior art (eg. , US Pat.
[0185] 8,469,294, incorporated herein by reference). Continuous tape element 27 can be rolled up and stored for later insertion into hose 10. Alternatively, continuous tape element 27 can go directly from the molding wheel to the extruder for hose 26. That is, the rolling of rails 25 and emitter 22 (including upper surface 22a and fins 22b) of the molding wheel is positioned within the die head extruding the hose 26 and thus forming the irrigation hose or tape 10. Suitable inlets (not shown) allow the passage of water from the flow path of the hose 11 to the flow path of the emitter 12 through of the issuer's inputs. Suitable outlets 28 are formed in the irrigation hose 10 above the outlet section of the emitter flow path, by means well known in the art.
[0187] These prior art emitter designs are non-limiting examples, and it is considered that other suitable emitter designs could be used with the present invention, including continuous emitter designs, hot melt emitter designs, discrete emitter designs, and stitched emitter designs. In FIG. 24 shows an example of a stitched emitter design. The emitter 1500 is operatively attached to a first side 1541a and a second side 1541b of a tape 1540 to form a tape flow path 1542 and an emitter flow path 1535. The emitter 1500 could be made consonant or non-consonant before installing the emitter 1500 within the seam of the 1540 tape. If this configuration is used, the inlet elements are positioned along the side near the flow path of the 1542 tape. For seam emitter designs, the row (s) are positioned along the side near the flow path of the belt.
[0189] To prolong the run time of the irrigation hoses or tapes, before flushing or replacement is necessary, embodiments of the disclosure include various projections and configurations for the inlet portions, pressure reducing sections and portions of output of the emitters, and the projections and configurations of the embodiments can be interchanged and / or combined in various ways. The terms hose and tape are used interchangeably herein. The emitters can be continuous emitters applied to the hoses in any suitable way, such as those described above. The various projections and configurations of the pressure reducing sections and outlet portions work together with the inlet portions to form an integrated emitter, in which the various projections and configurations of the inlet portions create resistance differences, to provide staged flow path protection against clogging (seepage) and / or to help successively or sequentially activate inlet spaces, prolonging the time that irrigation hoses are functional because inlet spaces are not they are clogged in one go. Rather, the water flows through the first inlet gaps until they become clogged, then the water flows through the second inlet gaps, etc. Normally, water will enter the holes in inlets near the pressure reducing section first and as the inlet ports become clogged, water will enter the next available inlet ports closest to the pressure reducing section.
[0191] The emitters of the embodiment generally include a base or floor with outwardly extending projections to form outlet sections, pressure reducing sections, and inlet sections. Optionally, the pressure sensitive sections can interconnect the pressure reducing sections and the outlet sections. Optionally, the pressure reducing sections can include at least one pressure sensitive element such as, for example, but not limited to, the inclusion of elastomeric material to allow for changes in dimensions in response to pressure changes. While one function of a pressure reducing section is to dissipate the differential pressure between the inlet and outlet sections, if a pressure sensitive section is present, it functionally fulfills a part of this differential pressure dissipation. For this reason, it is clear that references made here to the pressure reducing section could also include a combination of pressure reducing and pressure sensitive elements. The emitters form cavities with the wall of the belt to form flow paths of the emitters. The pressure reducing sections include intermediate portions between the first lanes and the second lanes. In some embodiments, the first and second lanes extend to and through the exit sections and interconnect with the end rails to terminate the exit sections. The term issuer includes discrete issuers and issuer segments that are part of continuous issuers.
[0193] In some embodiments, each of the entrance sections includes at least one row of first entrance elements that generally extends in accordance with one of the first and second lanes. The row, at least, includes a first proximal end close to the respective rail and a first distal end. The row may at least extend in a straight line or it may extend at an angle (s) out of one of the first and second lanes. In some embodiments, the entrance sections include at least a first row extending out of the first lane and a second row extending out of the second lane, one or both extending straight or extending at an angle (s ) with respect to the lanes. The second row includes the second entry elements and includes a second proximal end near the respective rail and a second distal end.
[0194] The inlet elements extend outward from the base of the emitter (similar to upper surface 22a in FIG. 3) to form inlet gaps, including gaps through which water from the belt flow path enters. in the emitter flow path. The input elements could have at least one profile selected from the group consisting of round, oval, rectangular, triangular, and compound angular. The input elements could include several different configurations, including different profiles, sizes, widths, lengths, and heights. The first input elements form the first gaps of the gate and, if there are second gaps, they form the second gaps of the gate. The inlet partitions could be formed by leaving space between the inlet elements and / or by heights between the floors of the inlet partition and the belt wall and / or the different configurations of the inlet elements. In some embodiments, the first row includes at least a first spacing and a second spacing and the second row, if used, includes at least a third spacing and a fourth spacing. In some embodiments, the distances between the floors of the inlet gap and the belt wall vary, thereby varying the heights of the gaps. In the first row, the floors of the first entry gap and adjacent entry elements form smaller gaps (first, lower in height) than the gaps formed by the floors of the second entry gap and adjacent entry elements ( second, higher) and, in the second row, if used, the floors of the third entrance gap and adjacent entrance elements form smaller gaps (third, lower height) than the gaps formed by the floors of the fourth entrance separation and the adjacent entrance elements (fourth, of greater height). The first and third heights could be the same, and the second and fourth heights could be the same. A combination of variable spacing and heights could also be used.
[0196] The inlet partitions could be used on one or both sides of the inlet section. If there are at least two rows of input gaps, they could be different. The input gaps in different rows could have different gap sizes, could be staggered or otherwise not aligned, and could vary linearly (spacing) and / or laterally (height) to create differences in strength and successively activate the gaps of entry. Also, the dimensions of the inlet gaps could depend on the desired function. For example, narrower gaps with lower flow rates, wider gaps with higher flow rates, etc. could be used. Also, for example, the dimensions of the gaps they could be selected to work in conjunction with the specific protrusions of the pressure reducing sections and the outlet portions to provide an overall integrated emitter.
[0198] Optionally, the emitters could include a guide element, and the guide element could include at least one guide rail portion. The at least a portion of the guide rail could be a relatively straight line, it could be angular, it could include compound angles, or it could include multiple configurations. The at least one portion of the guide rail could include a narrower portion and a wider portion, so that the distances between the input elements and the guide element, the input element to the gap or gaps could vary.
[0200] The portion of at least one guide rail could have any suitable length within the inlet portion and could even extend to the pressure reducing section. The portion of at least one guide rail could extend towards the inlet of the pressure reducing section and terminate near the inlet, at the inlet, or beyond the inlet in the pressure reducing section. In some embodiments, the guide element is generally parallel to the input elements. In some embodiments, the at least one guide rail portion is not parallel to the plurality of input elements. In some embodiments, the at least one guide rail portion is not parallel to the plurality of input elements. A portion of the guide element could be parallel to the inlet gaps, a portion could be angular or curved relative to the gaps in the inlet, and a combination of various configurations could be used. The optional guide element helps create resistance differences and vary the fineness of the filtration, to help successively activate the entry gaps, preferably from the proximal to the distal ends.
[0202] The distance between the input elements and the guide element could be arranged to improve the induction of sequential activation of the inputs and maintain the movement of the fine particles, and the distance could be varied to improve the sequential behavior. If more than one guide rail portion is used, the guide rail portions could have different distances from the input elements.
[0204] It has been found beneficial to combine, sequentially, the finest inlet gaps (gaps) and the least inlet gaps (gaps). fine. Finer inlet gaps are activated first and provide more protection (through finer filtration) of the flow restriction area (pressure reducing section). If there are field conditions where the finer inlet gaps are filled with debris (clogged), then the less fine inlet gaps allow the emitter to continue operating longer, providing the opportunity for maintenance to remove debris input gaps. The length of the inlet section could also be increased to provide additional inlet gaps. The input geometry encourages sequential activity to occur from fine to least fine to ... to least fine. This provides a final stage of protection in the form of wider inlet clearances so that the last remaining inlet clearances remain active until that maintenance can occur. Sequential behavior maximizes protection under normal circumstances and then wider input gaps (gaps) are used, if necessary, to maintain overall emitter operation for a longer period of time, thus allowing continuity of functionality until maintenance occurs.
[0206] Varying the heights and / or configurations of the inlet sections, pressure relief sections, and / or outlet sections has also been found to be beneficial. For example, the heights and / or configurations of the pressure relief sections could be optimized to accommodate the heights and / or widths of the inlet gaps. Heights could be varied by varying the thickness of the emitter base. The configurations could be varied by varying the shape of the input elements and / or the base of the emitter.
[0208] The embodiments of the emitters are schematically illustrated in the drawings. One of ordinary skill in the art will appreciate that various emitter components are of suitable thickness. Suitable thicknesses can range from 0.005 to 0.025 inches.
[0210] An example of the emitter portion 100, shown in FIG. 5, generally includes an outlet section (not shown), a pressure reducing section 104, and an inlet section 108. Emitter 100 forms a cavity with the belt wall to form a flow path of emitter 135 The pressure reducing section 104 includes a middle portion 106 between a first rail 105a and a second rail 105b.
[0211] In this example, the entrance section 108 includes a first row 109a of first entrance elements 110a and a second row 109b of second entrance elements 110b that generally extend in line with or parallel to the rails 105a and 105b, respectively. First row 109a includes a first proximal end 114a proximal to first rail 105a and a first distal end 116a, and second row 109b includes a second proximal end 114b near second rail 105b and a second distal end 116b. It is recognized that the first and second rows 109a and 109b could generally extend in line with or parallel to the first and second lanes 105a and 105b, as shown, or could extend at an angle (s) away from the first and second lanes. 105a and 105b. Alternatively, the lines could extend from the lanes differently. The row (s) could extend along a portion of the emitter or along the entire length of the emitter. At least one row could extend the entire length of the emitter. Also, two or more rows could be used, and the two or more rows could have different lengths. If used with a stitched emitter design, the row or rows are located along the side near the tape flow path.
[0213] The first and second inlet elements 110a and 110b extend upward from the base of emitter 101 (eg, a base is also shown in FIGS. 17A and 17B, similar to top surface 22a in FIG. 3) to form the first and second inlet gaps 118a and 118b, respectively, through which water from the ribbon flow path enters the emitter flow path 135. Although an oval profile 112b is shown, the First elements of and second inlet 110a and 110b could have at least one profile selected from the group consisting of round 112a, oval 112b, rectangular 112c, triangular 112d, and angular compound 112e, as shown in FIG 21. It is recognized that others could be used. suitable profiles. In this example, the first and second entry gaps 118a and 118b are formed by the spacing between adjacent entry elements. The first row 109a includes at least the first spacing 123a and the second spacing 123b and the second row 109b includes at least the third spacing 123c and the fourth spacing 123d. In this example, the inlet elements 110a and 110b are inclined inward toward the pressure reduction section 104 and are generally mirror images of each with a spacing closer to the pressure reduction section 104 and a spacing closer to distal ends 116a and 116b.
[0215] Optionally, the emitter 100 could include a guide element 128, and the guide element 128 could include at least one guide rail portion 130. In general, the guide rail portion Guide rail could be a relatively straight line, it could be angular, it could include compound angles, or it could include multiple configurations. In this example, the guide rail portion 130 at least includes a narrow portion 130a and a wide portion 130b, so that the distances between the inlet elements and the guide element vary, the inlet element at the gap. of guide member 132. Guide member 128 includes a guide rail portion 130 that forms a relatively narrow portion 130a proximal pressure relief section 104 that deflects into two guide rail portions 130 that are angled proximal to each other. narrow portion 130a and are parallel proximal to the distal ends forming a wide portion 130b. Gaps 132 are widest near narrow portion 130a and narrowest near wide portion 130b.
[0217] Various configurations of guide elements could be used. In another example, shown in Fig. 6, emitter 100 could have a 128 'guide element with 130' guide rail portions, which generally form a narrow portion 130a 'that deflects into two rail portions. guide 130 'forming a wide portion 130b' which tapers into a narrow portion 130a 'thus forming gaps 132' with varying distances.
[0219] An example emitter portion 200, shown in FIG. 7, generally includes an outlet section 202, a pressure reducing section 204, and an inlet section 208. The emitter 200 forms a cavity with the wall of the the tape to form a flow path of the emitter 235. The pressure reducing section 204 includes a median portion 206 between a first rail 205a and a second rail 205b. In this example, the first and second lanes 205a and 205b extend into and through the exit section 202 and are interconnected with an end rail 205c to terminate the exit section 202. This example of the emitter portion 200 is part of a continuous emitter, and the outlet portion 202 'is part of an outlet section of an adjacent emitter portion
[0221] In this example, the entry section 208 includes a first row 209a of first entry elements 210a and a second row 209b of second entry elements 210b that generally extend in line or parallel to the rails 205a and 205b, respectively. The first row 209a includes a first proximal end 214a proximal to the first rail 205a and a first distal end 216a, and the second row 209b includes a second proximal end 214b near the second rail 205b and a second distal end 216b. Rows 209a and 209b are generally symmetrical. It is admitted that the first and second rows 209a and 209b could generally extend in line or parallel to the first and second lanes 205a and 205b, as shown, or they could extend at angle (s) away from the first and second lanes 205a and 205b. Alternatively, the lines could extend from the lanes differently.
[0223] The first and second input elements 210a and 210b extend upward from the base of emitter 201 (for example, a base is also shown in FIGS. 17A and 17B, similar to top surface 22a in FIG. 3) to form the first and second inlets 218a and 218b, respectively, through which water from the ribbon flow path enters the emitter flow path 235. Although an oval profile 212b is shown, the first and second Input elements 210a and 210b could have at least one profile selected from the group consisting of round 112a, oval 112b, rectangular 112c, triangular 112d, and angular compound 112e, as shown in FIG 21. It is recognized that other suitable profiles could be used. Inlet elements 210a and 210b are inclined inward of pressure reducing section 204 to direct water towards pressure reducing section 204. In this example, the first and second inlet gaps 218a and 218b they are formed by the space between adjacent input elements. The first row 209a includes at least the first spacing 223a and the second spacing 223b and the second row 209b includes at least the third spacing 223c and the fourth spacing 223d. Therefore, in this example, there are two groups of input gaps in each row, and adjacent gaps 222 having different sizes. Optionally, emitter 200 could include a guide element 228, which in this example is a relatively straight line approaching the middle of the inlet portion that ends before pressure reducing section 204. Gap 232 is relatively constant between guide element 228 and input elements 210a and 210b.
[0225] Alternatively, as shown in Fig. 8, the rows are generally symmetrical and the input elements 310a and 310b are generally perpendicular (neutral) to the longitudinal axis of the emitter 200. In this example, there are three groups of input gaps at each row, and adjacent openings 322 have different sizes. A guide element 228 could be included and, in this example, the spacing 332 is relatively constant between the guide element 228 and the input elements 310a and 310b.
[0227] Alternatively, as shown in Fig. 9, inlet elements 410a and 410b are angled outward, away from pressure reducing section 204, to direct water toward the center of inlet section 208 and toward the reduction section of pressure 204. There are two groups of inlet partitions in each row, and adjacent openings 422 are of different sizes. Fig. 9 also illustrates an example of sequential activation of the inlet gaps as gaps near the proximal ends become plugged, thus allowing water to enter the emitter flow path closest to the middle of the portion of entry. As the gaps near the proximal ends are obstructed, successive openings are generally activated sequentially from the proximal ends to the distal ends to allow water to enter the flow path of emitter 235 '.
[0229] Alternatively, as shown in FIG. 10, the inlet elements 510a are angled outward from the pressure reducing section 204 and the inlet elements 510b are angled inwardly from the pressure reducing section. Guide element 528 is used to help direct water towards pressure reducing section 204. Fig. 11 shows a similar optional example without a guide element.
[0231] Alternatively, as shown in Fig. 12, the inlet elements 710a and 710b are inclined towards the pressure reducing section. The inlet elements 710a include openings with different sizes, with the smallest openings being close to the proximal end and the largest being close to the distal end, and at least one pair of adjacent openings 722 being different sizes. The inlet elements 710b are generally evenly spaced with openings of approximately the same size. Guide element 728 is generally parallel to inlet elements 710a and angles outwardly from the proximal end of inlet elements 710a to the distal end of inlet elements 710b. This provides gaps 232 that are wider in the vicinity of the proximal end and narrower in the vicinity of the distal end of the inlet elements 710b.
[0233] Alternatively, as shown in Fig. 13, each of the first and second rows includes four groups of inlet gaps formed by inlet elements 810a and 810b having different sizes, shapes, and spacing (aperture sizes). Adjacent openings 822 have different sizes. Optionally, a guide element 828 could be used.
[0235] An example of emitter portion 900, shown in FIG. 14, includes an outlet section (not shown), a pressure reducing section 904, an inlet section 908, and an outlet section 902 'of a adjacent emitter portion. Each row of items Entry gaps 909a and 909b include three sets of entry gaps, with adjacent openings 922 of different sizes, and a guide element 928 may be included. Entry gaps increase from the proximal ends to the distal ends of the gates. input elements. The guide element 928 is generally V-shaped, with the narrow portion 930a proximate a junction of the first and second groups of inlet gaps and the wide portion 930b proximate the third group and distal ends.
[0237] Alternatively, as shown in Fig. 15, the guide element 928 'is generally a longer V shape with the narrow portion 930a' near the distal ends and the wide portion 930b 'near the proximal ends.
[0239] Alternatively, as shown in Fig. 16, there is no guide element. It is recognized that no guide element or one of a variety of guide elements can be used.
[0241] FIGS. 17, 17A and 17B illustrate another example emitter portion 1000 with alternative spacing configurations. The emitter 1000 includes an outlet section 1002, a pressure reducing section 1004 and an inlet section 1008, and an outlet section 1002 'of an adjacent emitter portion. Inlet section 1008 includes inlet elements 1009a and 1009b, which may be evenly spaced as shown. In one example, shown in Fig. 17A, the separation floors gradually decrease in height between the inlet elements, gradually increasing the size of the opening from the pressure reducing section next to the distal ends. For example, a separation floor 1020c has a height 1024c that is higher near the pressure reducing section 1004, thus forming a relatively small opening with adjacent inlet elements 1009b, and a separation floor 1020d has a height 1024d which is lower near the distal ends, thus forming a relatively large opening with adjacent entry elements 1009b. Another possibility is that the separation floors are grouped with several separation floors of one height, several separation floors of another height, etc., and each group decreases in height. For example, as shown in Figure 17B, a first group G1 has separation floors 1020c 'high 1024c' that are formed with adjacent inlet elements 1009b, relatively small openings; a second group G2 has separation floors 1020d 'high 1024d' that are formed with the adjacent entrance elements 1009b, openings relatively large; and a third group G3 between the first and the second group has separation floors 1020e in height 1024e that are formed with adjacent inlet elements 1009b, openings of intermediate size. It is recognized that any suitable number of groups could be used. Also, instead of being generally parallel to the base, the parting floors could be angled to decrease heights. Therefore, the sizes of the inlet gaps could be formed not only by the space between adjacent gate elements, but also by the height of the gap floor and / or the angle of the gap floor, or a combination of both to vary the fineness of the filtration.
[0243] An example of the emitter portion 1100, shown in FIG. 18, includes an outlet section 1102, a pressure reducing section 1104, an inlet section 1108, and an outlet section 1102 'of a portion. of adjacent emitter. Each row of inlet elements 1109a and 1109b includes successively larger inlet gaps from the pressure reducing section 1104 proximate the distal ends. The profiles of the inlet elements 1109a and 1109b are compound angle 1112e to direct water towards the inlet section 1108 and towards the pressure reducing section 1104. In addition, the compound angle profiles 1112e could include tapered ends.
[0245] Exemplary emitter portions 1200a to 1200f, shown in FIGS. 19A through 19F respectively, include common protrusions indicated by similar reference numerals and include different protrusions that can be interchanged between embodiments. In these examples, the rows of inlet elements 1209a and 1209b are more closely spaced from each other, approaching a gap in a pressure reducing section (example of pressure reducing sections 1204a to 1204e in FIGS. 19A to 19E, respectively) and are gradually spaced further apart as they approach the outlet section. In these examples, the inlet elements 1209a and 1209b extend along the inlet section 1208 and the pressure reducing section to both outlet sections (only 1202 'is shown). Optionally, the inlet elements next to the pressure reducing section and the inlet elements next to the inlet section 1208 are both angled towards the junction of the pressure reducing section and the inlet section to direct the flow. water to the union and to the pressure reducing section. FIG. 19F is similar to FIG. 19A but includes a guide element 1228 that is V-shaped with a narrow portion near the inlet of the pressure reducing section 1204a and a wide portion near the outlet 1202 ', and the spaces between the inlet and the guide element is taper towards the distal ends. A guide element can be used with any of the embodiments.
[0247] Figures 20A through 20E illustrate the flow of water through pressure reducing sections 1204a through 1204e, respectively. The thicker and longer arrows indicate the primary flow of water through the pressure reducing sections, and the thinner and shorter arrows indicate the secondary flow of water through the pressure reducing sections. Areas 1206a through 1206e indicate where the primary water flow contacts resistance projections within pressure reducing sections, and areas 1207a through 1207d indicate where debris can accumulate in pressure reducing sections. Pressure reducing section 1204a is more efficient in creating a pressure drop but less efficient in transporting debris through the section than pressure reducing section 1204b, pressure reducing section 1204b is more efficient in creating a pressure drop but less efficient in transporting debris through the section than the pressure reducing section 1204c, the pressure reducing section 1204c is more efficient in creating a pressure drop pressure but less efficient in transporting debris through the section than the pressure reducing section 1204d, and the pressure reducing section 1204d is more efficient in creating a pressure drop but less efficient in transporting debris through the section than the pressure reducing section 1204e.
[0249] In FIG. 20A, pressure reducing section 1204a generally includes linear rails 1205a and resistance projections 1211a with faces 1212a angled relative to rails 1205a. Areas 1206a indicate where the primary flow line contacts resistance ledges 1211a, and areas 1207a are in the downstream trails of resistance ledges 1211a and form "dead zones" where recirculation debris can settle and accumulate. .
[0251] In Fig. 20B, pressure reducing section 1204b generally includes resistance projections 1211b with angular faces 1212b and angular tips 1213b. Angled tips 1213b direct current exiting the tips to contact subsequent resistor bosses 1211b at further locations along the faces of subsequent resistor bosses 1212b. This encourages a higher percentage of the debris to continue through the maze and a lower percentage of the debris to recirculate. Areas 1206b indicate where the primary flow line contacts resistor bosses 1211b, and areas 1207b are in the descending trails of resistor bosses 1211b and form "dead zones" where recirculating debris can settle and accumulate. Although not illustrated, the angular faces can be compound angles (more than one deviation from linear) or also curvilinear to direct current.
[0253] In Fig. 20C, pressure reducing section 1204c generally includes angular faces 1212c and also includes non-linear rails 1205c both to facilitate more efficient recirculation compared to pressure reducing section 1204a and to reduce areas 1207c. in the wake of resistance ledges 1211c. Areas 1206c indicate where the primary flow line contacts the 1211c resistor ledges, and 1207c areas are in the back trails of the 1211c resistor ledges and form "dead zones" where recirculation debris they can settle and accumulate. Although Fig. 20C shows non-linear curvilinear rails, a related benefit can be achieved by using two or more linear elements to form a non-linear rail between subsequent resistance bosses.
[0255] In FIG. 20D, the pressure reducing section 1204d generally includes non-linear rails 1205d and resistance bosses 1211d with curved composite angular faces 1212d and angular tips 1213d. Compared to the pressure reducing section 1204b, this design reduces areas 1207d and facilitates more efficient recirculation while also retaining the benefit of changing the primary flow line to be closer to the distal ends or tips of the rear resistance bosses 1211d. This example provides the benefits of pressure reduction in sections 1204b and 1204c. Areas 1206d indicate where the primary flow line contacts resistor bosses 1211d, and areas 1207d are in the downstream trails of resistor bosses 1211d and form "dead zones" where recirculation debris can settle and accrue.
[0257] In FIG. 20E, the pressure relief section 1204e generally includes non-linear rails 1205e that form the resistance bosses 1211e with no dead zones in the trailing trails of the resistance bosses 1211e. In this embodiment, the protrusions are formed by the non-linear rails. Resistance bosses 1211e include angle faces 1212e, and angle points 1213e. There are other similar configurations, as, for example, the resistance projections 1211e can include an angular straight face without the angled tip, or they may include more than one linear face combined to form a composite angled face with or without the angled tip. In the FIG 20E design, the resistor projections themselves perform the function of the rails to isolate the flow within the interior of the emitter from the fluid present outside of the emitter. This differs from traditional designs in which the outer rails isolate the flow within the pressure reducing section of the interface with the pressure outside the emitter, but do not serve the purpose of being a primary resistance overhang. In this example, the resistor projections extending from the "outer walls" are actually a portion of the outer walls themselves. Areas 1206e indicate where the primary flow line contacts resistance bosses 1211e, and there are no areas in the downstream trails of resistance bosses 1211e where recirculation debris can settle and accumulate.
[0259] In these examples illustrated in FIGS. 20A-20E, the overall resistance to clogging of a sequentially active inlet integrated emitter can be optimized by balancing the design of the inlets to match the ability of the pressure reducing sections to transport debris efficiently through output sections. The outlet section itself can be configured to have a capacity similar to that of the inlet and pressure reducing section with regard to waste transport. It is the combination of the inlet section design, the pressure reducing section design, and the outlet section design that optimizes the overall resistance to clogging for the emitter flow and space combinations. When designing an emitter with a longer available length for the pressure reduction section, a design with less efficient pressure drop creation can be chosen, while taking advantage of improved waste transport. The accompanying sequentially active inlet design would be selected to provide an optimized debris size to work with the design of the selected pressure reducing section. In this way, the inlet design does not become "too restrictive" compared to the pressure reducing section. In other words, if an emitter were designed in a standard way, the filtration provided by the inlets can become the weakest link in the overall design because it fills up quickly and requires system maintenance to remove accumulated debris from the projections. from the entrance. With this invention, the inlet design can be less restrictive (i.e., longer time between maintenance) by selecting a pressure reducing section and outlet section designs capable of passing larger debris by incorporating the inventions herein. Adapting the Inlet design, pressure reducing section design and outlet section design together, a general benefit can be achieved with respect to clogging resistance.
[0261] Fig. 46A illustrates a portion of an emitter of another embodiment that includes portions of a pressure reducing section with different configurations B, C, and D shown in FIGS. 46B, 46C and 46D, respectively. The use of changing geometry such as, but not limited to, those illustrated in Fig. 46A has benefits. For example, when water and debris first enter the pressure reduction section, the speed lines are not yet established. This is a location where the pressure reducing section may be most vulnerable to plugging. For this reason, geometry as illustrated in Fig. 46D, which is similar to that shown in Fig. 20E without "dead zones", can be helpful. However, the geometry according to Fig. 46D is not especially efficient in creating a pressure drop. As the water and debris move further along the pressure reduction section, the currents become more frequent and the mixture is better able to pass through a section without depositing debris, as indicated by the thicker arrows . A section illustrated in Fig. 46C, which is similar to Fig.20D, may be appropriate here. However, although it is more efficient in pressure drop than Fig. 46D, Fig. 46C it is still not as efficient as Fig. 46B. Eventually, when the water and debris have passed further still, the streamlines are stronger still and geometry analogous to Fig. 46B may be appropriate. Geometry shown here has rails of varying configurations (increasing radius of curvature, curvilinear, although not shown here could also become straight rail further down, linear compound angle, rail dimension, rail separation distance) and protrusions of varying configurations (curved compound angle, linear compound angle, different tip angles, linear without tip angle, different linear angles, interval (s) between protrusions, feature shape, feature dimension). Included in this example are portions similar to those in FIGS. 20C, 20D and 20E, however, all suitable geometries can be used, including any suitable continuity of changing geometries. For example, the setting at 1 may differ from 2, which may differ from 3, which may differ from 4, which may differ from 5, which may differ from 6, which may differ from 7, which may differ from 8, which may differ from 9, which may differ from 10, etc. These configurations could be transitions from a first portion configuration to a second portion configuration, etc. For example, locations 1, 2, and 3 may include gradual changes in configurations from a first portion to a second. portion, locations 4, 5, and 6 may include gradual changes in configurations from a second portion to a third portion, etc.
[0263] An example emitter portion 1300, shown in Figures 22A and 22B, includes an elongated inlet section 1308 with relatively thin and closely spaced inlet elements close to the pressure reducing section 1304 and relatively thick inlet elements. and more widely spaced near the distal ends of input elements 1309a and 1309b. The inlet elements could be generally rectangular, as shown, or tapered to direct water toward pressure reducing section 1304. FIG.22B includes a guide element 1328 similar to guide element 1228. This example provides gaps of Multi-width inlet (openings) for protection of the flow path in stages against obstruction (fine, less fine, ...) or for sequential activation of the inlet.
[0265] An example emitter portion 1400, shown in Figures 23A and 23B, includes an elongated inlet section 1408 with relatively thin and closely spaced inlet elements close to the pressure reducing section 1404, relatively thick inlet elements. and further spaced near the distal ends of input elements 1409a and 1409b, and input elements of intermediate size and spaced between them. The inlet elements could be generally rectangular, as shown, or tapered to direct water toward the pressure reducing section 1404. FIG. 23B includes a guide element 1428 similar to guide elements 1228 and 1328. This example provides inlet gaps (apertures) of multiple widths for protection of the staged flow path against obstruction (fine, less fine, .. less fine) or for sequential activation of the input.
[0267] FIGS. 25A and 25B illustrate inlet elements 1610 within the inlet section along one side of emitter 1600. Although inlet elements 1610 have a generally uniform density D1, they could have varied configurations to provide different sizes of gaps and gaps. input. FIG. 25B illustrates how debris could accumulate near the 1610 input elements.
[0269] FIGS. 26A and 26B illustrate the inlet elements 1710 within the inlet section along one side of the emitter 1700. This example shows that the inlet elements 1710 have a first spacing density D2 that forms larger openings near the proximal end. and a second separation density D3 which forms smaller openings near the distal end. Larger openings near the proximal end prevent larger debris, such as those typically present during irrigation initiation, from clogging the inlet section. Larger openings prevent larger debris from entering the inlet section, while allowing water to enter the emitter's flow path. As larger openings become clogged, for example, by larger debris during startup, smaller openings allow water to enter the emitter flow path, as shown in Fig. 26B.
[0271] The 1600 and 1700 emitters could be used with a variety of hoses or tapes, including, but not limited to, seam installations with the inlets in fluid communication with the flow path of the hose or tape.
[0273] Fig. 27 illustrates an emitter 1800 with input elements 1810 having three different densities D4, D5 and D6 forming three aperture sizes. Although different arrangements could be used, this example includes smaller openings formed in D4 that interconnect larger openings formed in D5 and D6.
[0275] In general, FIGS. 28-30 illustrate that the outer inlet elements have the proximal ends near the pressure relief sections and the distal ends next to the outlet sections. If more than one row of input elements is used, one or more of the rows could include different aperture sizes. For example, Figures 29 and 30 illustrate representations where the inner inlet elements are evenly spaced and the outer inlet elements are varied spaced. Furthermore, the input elements may be angled relative to the emitter rails, which could also be angled, relative to the longitudinal axis of the emitter.
[0277] FIG. 28 illustrates emitters 1900 and 1900 'having input elements 1910 and 1910' along one side of the emitters with a variety of configurations and different aperture sizes near different sections of the emitters. For example, close to the inlet section and the pressure reducing section, the inlet bars 1910a form smaller openings between the inlet bars, and close to the pressure reducing sections and the outlet sections, the Entry bars 1910b, 1910c, 1910b 'and 1910c' form larger openings between the entry bars. In addition to the longitudinal spacing between adjacent input elements, the Side lengths of the inlet elements 1910a, 1910b, 1910c and 1910d could differ, as shown, in order to define changing distances between the innermost portions of the inlet elements and the outermost portions of the inner rails of the inlet elements. entry, as a means of encouraging sequentially active entries. In this scenario, a possible advance could generally be for the water to flow first through the gaps formed by the inlet elements 1910a and then into the inlet portion either directly or through a gap between the inlet elements. entrance and lane. When the openings formed by the inlet elements 1910a were obstructed, water would enter the openings formed by the inlet elements 1910b and 1910d ', and when these openings were obstructed, the water would enter the gaps formed by the inlet elements 1910c. and 1910c '. Water flowing through the openings formed by inlet elements 1910c may flow to one or both adjacent emitters, and water flowing through the openings formed by inlet elements 1910d and 1910b 'flows into the portion of nearest issuer input. Although this possible scenario is illustrated and described, it is understood that different advancements could occur.
[0279] FIG. 29 illustrates a emitter 2000 having internal entry elements 2010 and external entry elements 2011 along one side of the emitter 2000. Optionally, one side 2005a of the rails could include one or more corner portions and the internal entry 2010 elements. They could also be angled with respect to the longitudinal axis of the emitter. The other side 2005b could also include one or more corner parts.
[0281] FIG. 30 illustrates an emitter 2100 having internal input elements 2110 and external input elements 2111, and the rails 2105a and 2105b include angular portions, along both sides of the emitter 2100. The angular portions of rails 2105a and 2105b need not be symmetrical with respect to the longitudinal axis of the emitter. An optional 2128 guide element is also shown.
[0283] Fig. 31 illustrates an emitter 2200 having the input elements 2210 formed with different configurations and aperture sizes, and one side is longer than the other. Fig. 31A illustrates inlet elements differently that form an effective inlet gap G. The effective inlet gap defines an inlet gap.

[0305] 7. One or more input rows use the relative position of two or more input element profiles to define effective input gaps.
[0307] An example of the emitter portion 3000, shown in Fig. 32, generally includes an outlet section 3002, a pressure reducing section 3004, an inlet section 3008, and a portion of an outlet section 3002. 'of an adjacent emitter portion extending from a base 3001. The emitter 3000 forms a cavity with the wall of the hose or tape to form a flow path of the emitter. Pressure reducing section 3004 includes a middle portion 3006 between a first rail 3005a and a second rail 3005b, and an end portion of rail 3005c interconnects the first and second rail portions 3005a and 3005b near an exit.
[0309] In this example, entrance section 3008 includes a first row 3009a of first entrance elements 3010a and a second row 3009b of second entrance elements 3010b that generally extend in line or parallel to lanes 3005a and 3005b, respectively. The first row 3009a includes a first proximal end near the first rail 3005a and a first distal end, and the second row 3009b includes a second proximal end near the second rail 3005b and a second distal end. It is recognized that the first and second rows 3009a and 3009b could extend generally in line or parallel to the first and second lanes 3005a and 3005b, as shown, or could extend at an angle (s) away from the first and second lanes 3005a and 3005b. Alternatively, the lines could extend from the lanes differently. The row (s) could extend along a portion of the emitter or along the entire length of the emitter. At least one row could extend the entire length of the emitter. Also, two or more rows could be used, and the two or more rows could have different lengths. If used with an emitter design in the seam, the row or rows are positioned along the side near the flow path of the tape.
[0310] The first and second inlet elements 3010a and 3010b extend upwardly from the base of emitter 3001 to form the first and second inlet gaps 3018a and 3018b, respectively, through which the water in the the tape enters the emitter flow path. Although an oval profile is shown, the first and second input elements 3010a and 3010b could have at least one profile selected from the group consisting of round, oval, rectangular, triangular, and compound angular. It is recognized that other suitable profiles could be used. In this example, the first and second inlet gaps 3018a and 3018b are formed by various configurations of the adjacent inlet elements. It is recognized that the space between adjacent input elements, instead of or in addition to the various configurations, could be used to form the input gaps. Optionally, the emitter 3000 could include a guide element (not shown).
[0312] It is recognized that various configurations of inlet sections, pressure reducing sections and outlet sections can be used. For example, the base heights (formed by the thickness of the emitter base) could vary in height and the inlet elements (pillars) could vary in spacing and / or thickness and / or configuration. Some configuration examples are shown in FIGS. 32A, 32B, 32C, 32D and 32E and these examples are not exhaustive. In these examples, there are different settings between the sections, and the input sections include different settings. Fig. 32 includes several section view lines illustrating where on the emitter the section views shown in FIGS. 32A, 32B, 32C, 32D, and 32E. Generally, section view A-A is a cross section in the outlet section showing the base between the rails. Section view B-B is a cross section in the center of the pressure relief section showing the base between the rails. Section view C-C is a cross section in the pressure reducing section near the inlet section showing the base between the rails. Section view D-D is a cross section in the middle of the inlet section showing the base between the inlet elements. Sectional view E-E is a cross section in the inlet section near its distal end showing the base between the inlet elements. Section view F-F is a side view of the inlet section. The scale for section view F-F differs from section views A-A to E-E.
[0314] In one example, shown in Fig. 32A, the base heights and rail thicknesses are very similar in section views AA, BB and CC. Inside the section entrance 4008 (Section View FF), base heights vary. Between the rows of input elements 4009b, a central portion of the base height is similar to the base heights in section views AA, BB, and CC. Portions of the base heights on opposite sides, near each row of inlet elements 4009b, are preferably higher than the central portion and are preferably raised in height from the proximal distal end toward the pressure reducing section. , and the inlet elements are preferably reduced in height from the proximal distal end towards the pressure reducing section. Therefore, the gaps near the pressure reducing section (eg section view DD) are smaller than gaps near the distal end (eg section view EE), but a channel 4001a created by the base 4001 between the rows of inlet elements 4009b is similar in height to the height near the pressure reducing section to the height near the distal end. Channel 4001a is a step into the pressure reduction section.
[0316] In this example, the settings between input elements 4009b vary. For example, a separation floor 4020c (which could be a one-to-many) has a height 4024c that is taller close to the pressure reduction section, thus forming a relatively small opening with adjacent inlet elements 4009b, and a separation floor 4020d (which could be a one-to-many) has a height 4024d that is lower near the distal ends, thus forming a relatively large opening with adjacent inlet elements 4009b. This is also shown in Fig. 33A.
[0318] In Fig. 32B, the base heights vary between sections as shown in section views AA, BB, CC, DD, and EE. In section view FF, inlet section 5008 includes formed parting floors by base 5001 gradually decreasing in height from the proximal pressure reduction section (eg section view DD) to the distal end (eg section view EE) of the inlet section and thus , the settings between the input items vary. For example, a separation floor 5020c (which could be a one-to-many) has a height 5024c that is higher near the pressure reducing section, thus forming a relatively small opening with adjacent inlet elements 5009b, and a separation floor 5020d (which could be a one-to-many) has a height 5024d that is lower near the distal ends, thus forming a relatively large opening with adjacent entry elements 5009b.
[0319] Preferably, the base heights between the rows of inlet elements 5009b are similar to those of the adjacent separation floors. This is also shown in Fig. 33B.
[0321] In Fig. 32C, the base heights vary between sections as shown in section views A-A, B-B, C-C, D-D and E-E. Within the inlet section 6008, between the rows of inlet elements 6009b, a central portion of the height of the base is preferably concave. Portions of the base heights on opposite sides, proximate each row of input elements 6009b, are preferably taller than the central portion and are preferably raised in height from the proximal distal end (e.g., section view EE ) toward the pressure reducing section (eg, sectional view DD), and the inlet elements are preferably raised in height from the proximal distal end toward the pressure reducing section. Therefore, the gaps near the pressure reduction section (eg section view DD) are larger than gaps near the distal end (eg section view EE), but a channel 6001a created by the base 6001 between rows of input elements 6009b is shorter near the pressure reduction section and tallest near the distal end. Channel 6001a is a step into the pressure reduction section.
[0323] In this example, the settings between input elements 6009b vary. For example, a separation floor 6020c (which could be a one-to-many) has a height 6024c that is lower near the pressure reduction section, thus forming a relatively large opening with adjacent inlet elements 6009b, and a separation floor 6020d (which could be a one-to-many) has a height 6024d that is tallest near the distal ends, thus forming a relatively small opening with adjacent entry elements 6009b. This is also shown in Fig. 33C.
[0325] In FIGS. 32D and 32E, the base heights vary between sections as shown in section views AA, BB, CC, DD, and EE. However, as shown in Section Views DD and EE, the base heights could be the same in inlet sections 7008 and 8008. In Section Views FF, it is shown that the spacing between inlet elements 7009b and 8009b and the base heights could be the same in inlet sections 7008 and 8008.
[0326] In FIGS. 32A, 32B, 32C, 32D, and 32E, alternatively, the separation floors could be in groups with a number of separation floors of one height, a number of separation floors of another height, etc. with each group decreasing in height. Also, instead of being generally parallel to the base, the parting floors could be angled to decrease heights. Therefore, the sizes of the inlet gaps could be formed not only by the space between adjacent gate elements, but also by the height of the gap floor and / or the angle of the gap floor, or a combination of both to vary the fineness of the filtration. Furthermore, the base could include a channel between the inlet elements and the channel could be square, concave, V-shaped, or any other suitable shape or configuration.
[0328] Generally, the height of the base may differ in one or more places from the emitter portion. The height of the base between the inlet elements can match the height of the base in the middle of the inlet elements. The height of the base between the inlet elements can match the height of the base in the pressure reducing section. The height of the base in the middle of the inlet section can match the height of the base in the pressure reducing section. The height of the base inside the pressure relief section can match the height of the base in the outlet section. The height of the base in the middle of the inlet section can be uniform or it can vary in height in one or more places. The height of the base between the elements of the inlet section can be uniform or it can vary in height in one or more places. The height of the base within the pressure relief section can be uniform or it can vary in height in one or more places. The height of the base within the outlet section can be uniform or it can vary in height in one or more places. Any suitable combination of these base heights can also be used.
[0330] In another example the emitter portion 9000, shown in Fig. 34, includes a guide element 9028 between input elements 9010a and 9010b. An example of how the emitter portion can be connected to an irrigation hose or tape 9040 is shown in FIG. 35. The emitter portion could have various configurations. The entry elements could extend further, be flush, and / or have a short edge formed between the base or floor and the entry elements. The gate elements may be at constant heights above the height of the base or may vary in height at one or more places along the length of an individual gate element or between groups of gate elements. One or more of the input elements can touch completely, touch partially, or be spaced a desired distance from the inside surface of the hose wall or irrigation tape. A guide element could be included, which could be at least partially touching or spaced a desired distance from the wall of the inner surface of the irrigation hose or tape. At least a portion of the guide member could be fully touching, partially touching, or spaced a desired distance from the interior surface of the irrigation hose or tape wall. Examples of possible configurations are shown in Figures 35A, 35B and 35C.
[0332] In FIG. 35A, the inlet elements 10010a and 10010b extend upward and then outward from the base 10001 toward the hose or irrigation tape 9040 forming protrusions 10011a and 10011b and the notches 10012a 10012b approach their outer sides thus extending the surfaces that they may come into contact with the 9040 irrigation hose or tape during use. A guide element 10028 interconnects the base 10001 and the hose or irrigation tape 9040 between the inlet elements 10010a and 10010b.
[0334] In FIG. 35B, inlet elements 11010a and 11010b extend upward from base 11001 and interconnect base 11001 and irrigation hose or tape 9040. A guide element 11028 interconnects base 11001 and irrigation hose or tape 9040 between input elements 11010a and 11010b. This is an example that the ends of the input elements 11010a and 11010b are flush with the outer edges or sides of the base 11001.
[0336] In Fig. 35C, inlet members 12010a and 12010b extend upwardly from base 12001 and are preferably inserted from the outer sides of base 12001, thus forming notches 12012a and 12012b near the outer sides. The upper outer portions of the inlet elements come into contact with the irrigation hose or tape 9040, and the inwardly extending protrusions 12011a and 12011b formed by the upper inner portions of the inlet elements do not come into contact with the 9040 irrigation hose or tape, but may selectively come into contact with the 9040 irrigation hose or tape during use.
[0338] In another example, emitter portion 13000, shown in Fig. 36, includes rows 13009a and 13009b of inlet elements 13010a and 13010b that are more closely spaced from each other, near the pressure reducing section. 13004 and gradually separating as they approach the exit sections (only outlet section 13002 'shown). In this example, inlet elements 13010a and 13010b extend along inlet section 13008 and pressure reducing section 13004 to both outlet sections. Optionally, lanes 13005a and 13005b could be non-linear. For example, the internal surfaces could be concave so that the fluid is directed towards the extensions 13007a and 13007b of the rails as it flows towards the outlet, the extensions being compatible with inlet filtration. For a given inlet and flow combination, the curvature of the lanes can be set to create a flow pattern between the extensions, so that settlement areas are reduced, and particles able to pass through the given inlet gaps propagate downstream through the pressure reduction section and out of the outlet section. Non-linear rails could be used with other emitter configurations.
[0340] FIGS. 37-40 illustrate embodiments with tapered inlet sections that include two or more inlet elements that form each row. In Fig. 37, a pressure reducing section 3704 interconnects an inlet section 3708 and an outlet section 3702. The outer inlet elements 3710a and the inner inlet elements 3711a are staggered to form a first row 3709a and the inlet elements. The outer inlets 3710b and the inner inlets 3711b are staggered to form a second row 3709b in the inlet section 3708. In this example, the outer inlets have triangular profiles with their vertices facing inward and the inner inlets they have circular profiles. The first and second rows 3709a and 3709b are spaced closer together, near the outlet section 3702 'of the adjacent emitter portion, and further spaced, near the pressure reducing section 3704 to form a cone T1, as indicated by the dashed lines. In this way, the effective inlet spacing is successively larger, moving from the inlet elements close to the pressure reducing section towards the inlet elements close to the outlet section. This allows the sequentially active input elements to go from fine to less fine filtration. In addition, the outer inlet elements 3710a and 3710b and the inner inlet elements 3711a and 3711b are further spaced from each other, near the outlet section 3702 'of the adjacent emitter portion for less fine filtration and closer spaced between. yes, near an opening in pressure reducing section 3704 for finer filtration.
[0341] In Fig. 38, a pressure reducing section 3804 interconnects an inlet section 3808 and an outlet section 3802. The outer inlet elements 3810a and the inner inlet elements 3811a are staggered to form a first row 3809a and the outer elements entrance 3810b and internal entrance elements 3811b are staggered to form a second row 3809b in entrance section 3808. In this example, the exterior entrance elements have triangular profiles with their vertices facing inward and the interior entrance elements they have circular profiles. The effective spacings are defined by the relative distances between 3810a and 3811a and between 3810b and 3811b and vary between groups of input elements. The first and second rows 3809a and 3809b are spaced closer together, near the outlet section 3802 'of the adjacent portion of the emitter in group G1 and further spaced, near the pressure reducing section 3804 in group G3 with an intermediate spacing in group G2 between them. Furthermore, the outer inlet elements 3810a and 3810b and the respective adjacent inner inlet elements 3811a and 3811b are spaced from each other closer to the outlet section 3802 'of the adjacent emitter portion for less fine filtration and spaced closer to a 3804 pressure reducing section opening for finer filtration.
[0343] In Fig. 39, a pressure reducing section 3904 interconnects an inlet section 3908 and an outlet section 3902. The outer inlet elements 3910a and the inner inlet elements 3911a are staggered to form a first row 3909a and the outer elements Entrance members 3910b and interior entrance elements 3911b are staggered to form a second row 3909b at entrance section 3908. In this example, the exterior and interior entrance elements have triangular profiles with their vertices facing inwardly in the row. The effective spaces are defined by the relative distances between 3910a and 3911a and between 3910b and 3911b and vary between groups of input elements and between input elements that form a cone. The first and second rows 3909a and 3909b are spaced closer to each other, near the outlet section 3902 'of the adjacent portion of the emitter in group G4, and further spaced, near the pressure reducing section 3904 in group G5 with an intermediate space between them forming a cone T2, as indicated by the dashed lines. In addition, the outer inlet elements 3910a and 3910b and the inner inlet elements 3911a and 3911b are further spaced, closer to the outlet section 3902 'of the adjacent emitter portion for less fine filtration and more closely spaced, closer to an opening in the pressure reducing section 3904 for finer filtration.
[0344] In Fig. 40, a pressure reducing section 4004 interconnects an inlet section 4008 and an outlet section 4002. The outer inlet elements 4010a and the inner inlet elements 4011a are generally aligned with the intermediate inlet elements 4012a between them. Adjacent interior and exterior entrance elements 4010a and 4011a to form a first row 4009a and the exterior entrance elements 4010b and interior entrance elements 4011b are generally aligned with the intermediate entrance elements 4012b between adjacent exterior and interior entrance elements 4010b and 4011b to form a second row 4009b in inlet section 4008. In this example, the outer and inner inlet elements have triangular profiles with their vertices facing inward in the row and the intermediate inlet elements have circular profiles. The first and second rows 4009a and 4009b are spaced closer to each other, near the outlet section 4002 'of the adjacent emitter portion and further spaced, near the pressure reducing section 4004 to form a cone T3, as indicated by the dashed lines. In addition, the outer inlet elements 4010a and 4010b and the inner inlet elements 4011a and 4011b are spaced further apart, near the outlet section 4002 'of the adjacent emitter portion for less fine filtration and closer spaced, closer to an opening of the pressure reducing section 4004 for finer filtration. In this example, the outer and inner inlet elements are brought into contact with each other and then fused as they approach the pressure reduction section.
[0346] FIGS. 41-43 illustrate embodiments with input elements that extend along the emitter portion, effectively extending a portion of the input portion along the emitter portion. In Fig. 41, a pressure reducing section 4104 interconnects an inlet section 4108 and an outlet section 4102. In this example, the gaps of the adjacent outer inlet elements 4110a and 4110b and the adjacent inner inlet element 4111a and 4111b are not fixed. The outer inlet elements 4110a and the inner inlet elements 4111a are staggered to form a first row 4109a and the outer inlet elements 4110b and the inner inlet elements 4111b are staggered to form a second row 4109b in the inlet section 4108. In this example, the outer entrance elements have triangular profiles with their vertices facing inward and the interior entrance elements have circular profiles. The first row 4109a extends along the length of the emitter portion, effectively extending the Inlet portion along the length of the emitter portion with pressure reducing section 4104 and outlet section 4102 positioned along a distal end portion of the first row 4109a of the emitter portion. The outer inlet elements 4110a and 4110b and the inner inlet elements 4111a and 4111b are further spaced from each other, near the outlet sections 4102 and 4102 'for less fine filtration and more closely spaced from each other, near an opening of pressure reducing section 4104 for finer filtration.
[0348] In Fig. 42, a pressure reducing section 4204 interconnects an inlet section 4208 and an outlet section 4202. The outer inlet elements 4210a and the inner inlet elements 4211a are staggered to form a first row 4209a and instead of a second row of input elements, a rail 4205b extends along a length of the emitter portion that is part of emitter sections 4202, 4204, and 4208. In this example, the outer and inner input elements have oval profiles with different dimensions. The first row 4209a extends along the length of the emitter portion, effectively extending the inlet portion along the length of the emitter portion with pressure reducing section 4204 and outlet section 4202 positioned at along a distal end portion of the first row 4209a of the emitter portion. Rows 4205a and 4205b form the sides of pressure reducing section 4204 and outlet section 4202. External inlet elements 4210a are further spaced, closer to outlet sections 4202 and 4202 'for less fine filtration and spaced apart. closer, next to a pressure reduction section opening 4204 for finer filtration. As illustrated, the internal input elements 4211a are consistently spaced, however it is recognized that they could vary in spacing.
[0350] In Fig. 43, a pressure reducing section 4304 interconnects an inlet section 4308 and an outlet section 4302. The outer inlet elements 4310a form a first row 4309a and, instead of a second row of inlet elements, a Rail 4305b extends along a length of the emitter portion that is part of emitter sections 4302, 4304, and 4308. In this example, the outer input elements have oval profiles of various sizes. The first row 4309a extends along the length of the emitter portion, effectively extending the inlet portion along the length of the emitter portion with the pressure reducing section 4304 and the outlet section 4302 positioned at along a distal end portion of the first row 4309a of the emitter portion. Rows 4305a and 4305b form the sides of the pressure reducing section 4304 and outlet section 4302. The outer inlet elements 4310a are further spaced from each other, close to the outlet sections 4302 and 4302 'for less fine filtration and spaced closer to each other, close of an opening in the pressure reducing section 4304 for finer filtration. Proximate a midsection of the pressure reducing section 4304, the outer inlet members 4310a extend closer to the rail 4305a to increase resistance at that location compared to the pressure reducing section near the pressure reducing section. input, to further improve the sequential behavior of the input.
[0352] FIGS. 44 and 45 illustrate embodiments with nested input elements. In Fig. 44, inlet section 4408 includes interior inlet elements 4411 separated from outer inlet elements 4410a and 4410b with rails 4405a and 4405b, respectively. These rail portions act as guide elements to help direct flow into the pressure reducing section 4404. The inlet elements are shown with oval and circular profiles, but any suitable profile can be used. Various configurations are shown, and these configurations can be combined into any desired combination, including one or more of the configurations. For example, Table 1 shows the possible configurations:

The "theta" angle and the "delta" angle may or may not be equal and the angles may be equal to 0 degrees. In configurations B and E, it is preferable that the angle "theta" is greater than or equal to 0 degrees.

Inlet elements 4511. A rail 4505 is positioned between the internal inlet elements 4511 and the outer rail elements 4510b as a guide element to help direct flow to the pressure reducing section 4504. Although one rail is shown , more than one can be used. Input elements are shown with oval and circular profiles, but any suitable profile can be used.
