MULTIFUNCTION ASPERSION HEAD
FUNDAMENTALS [0001] This disclosure generally refers to the field of valves for directing fluids to multiple outlets. More specifically, the disclosure refers to sprinkler head assemblies for use on taps to direct fluid (e.g., water) to one or more outlets to thereby provide multiple sprinkler head functions.
[0002] Taps can include a body and a spray head from which water is emitted. Conventional spray heads can include a valve to switch between two functions, for example, aerated and non-aerated water streams. There is a need for an improved valve to distribute water between functional outlets. There is no additional need for a valve that provides a spray head with more than two functions.
SUMMARY [0003] One modality refers to a fluid regulating valve including a body, a first redirector and a second redirector. The body includes an inlet configured to receive a fluid supply, a first chamber, a second chamber and a third chamber. The first redirector is movable in relation to the body between a first position and a second position. When the first redirector is in the second position, the first chamber is smoothly connected to the input and the second chamber is smoothly disconnected from the input. When the first redirector is in the first position, the second chamber is smoothly connected to the input and the first chamber is smoothly disconnected from the input. The second redirector is movable in relation to the body between a first position and a second position. When the second redirector is in the second position, the third chamber is seamlessly connected to the second chamber. When the second
4818-2944-5929.1
2/39 redirector is in the first position, the third chamber is fluidly connected to the second chamber.
[0004] The fluid regulating valve body may additionally include a first outlet fluidly connected to the first chamber; a second exit; and / or a third outlet fluidly connected to the third chamber. When the second redirector is in the first position, the second outlet can be seamlessly connected to the second chamber. When the second redirector is in the second position, the second outlet can be smoothly disconnected from the second chamber.
[0005] The fluid regulating valve can be configured such that at least a portion of the second redirector is arranged in a portion of the third chamber that extends in a longitudinal direction through the body, such that the second redirector moves in a longitudinal direction between the first and second positions.
[0006] The fluid regulating valve can be configured such that the first chamber of the body includes a first portion that receives at least a portion of the first redirector and a second portion fluidly connected to the first outlet. The first portion of the first chamber can extend in a radial direction that is transversal to the longitudinal direction, such that the first redirector moves in the radial direction between the first and second positions. The second portion of the first chamber may extend at an angle to the first portion.

DETAILED DESCRIPTION [00071] Referring generally to FIGURES, sprinkler heads configured to provide functions are disclosed in this document.
4818-2944-5929.1
11/39 multiple sprinklers. The sprinkler heads can be configured for use with taps or can be separate sprinklers (for example, side sprinklers). The spray head includes a valve (for example, a fluid regulating valve) having one or more chambers. For example, the valve can include a body that defines a first chamber, a second chamber and a third chamber. The sprinkler head also includes an inlet configured to receive a supply of fluid (for example, water). For example, the body can include the entry. The valve also includes at least one redirector. For example, the valve can include a first redirector and a second redirector. The first redirector is mobile between a first position and a second position. According to an exemplary modality, when the first redirector is in the second position, the first chamber is connected smoothly to the entrance and the second chamber is disconnected smoothly from the entrance; and when the first redirector is in the first position, the second chamber is smoothly connected to the entrance and the first chamber is smoothly disconnected from the entrance. The second redirector is mobile between a first position and a second position. According to an exemplary modality, when a second redirector is in the second position, the third chamber is fluidly connected to the second chamber; and where, when the second redirector is in the first position, the third chamber is fluidly disconnected from the second chamber. The valve, like the body, can include one or more outlets. For example, the body can include a first outlet, a second outlet and a third outlet. The first outlet can be fluidly connected to the first chamber and the third outlet can be fluidly connected to the third chamber. According to an exemplary modality, when the second redirector is in the first position, the second outlet is fluidly connected to the second chamber, and when the
4818-2944-5929.1
12/39 second redirector is in the second position, the second outlet is disconnected with fluidity from the second chamber.
[00072] The spray head can include one or more outlet members, where each outlet member is configured to provide a different spray function (for example, operating mode). For example, the spray head can include a first outlet member, a second outlet member and a third outlet member. The first outlet member may include a first plurality of nozzles that receive fluid from the first chamber. The second outlet member can include at least one nozzle that is fluidly connected to the second chamber when the second redirector is in the first position. The third outlet member may include a second plurality of nozzles that receive fluid from the third chamber. The first plurality of nozzles provides a first function, the at least one nozzle of the second outlet member provides a second function different from the first function and the second plurality of nozzles provides a third function different from the first and second functions.
[00073] A tap sprinkler head may include a valve that directs water between an aerated outlet and an un-aerated outlet. However, as improved tap technology and specialized spray patterns can be used to use water more efficiently, there is a need for a valve that can deliver water to multiple functional outlets. According to several modalities, the spray head has three or more possible functions. According to the exemplary modality shown, the spray head has three possible functions.
[00074] FIGS. 1-7 illustrate an exemplary embodiment of a spray head 210 configured as a multifunction sprinkler. The sprinkler head 210 includes a valve 239 for controlling a flow of fluid (e.g., water) through the sprinkler head 210 and at least one
4818-2944-5929.1
13/39 outlet (for example, a member outlet) configured to direct fluid out of the spray head 210. The spray head 210 additionally includes at least one actuator configured to control valve operation 239 to switch between the two or more sprinkler functions. Each actuator can be configured as a lever, a switch, a button 24 or other suitable settings. The sprinkler head 210 may include one or more features (for example, captive screws, pivots, guides, protrusions, protrusions, shafts, etc.) that are configured to orient and / or facilitate the movement of the actuator. Actuating the actuator causes a change in the operation (for example, volume control, function control, etc.) of the spray head 210. The actuator (s) and the function of the spray head 210 are described in more detail below .
[00075] As shown in FIG. 6, the spray head 210 extends along a longitudinal axis L and includes an inlet 223 configured to receive a supply of fluid. The sprinkler head 210 may include a connector 222 configured to couple the sprinkler head 210 to another member, such as a tap, a supply hose, etc. Connector 222 can be configured close to inlet 223. For example, connector 222 can define inlet 223, which is fluidly connected (for example, in fluid communication with) to valve 239 of sprinkler head 210 to introduce fluid on valve 239. According to an exemplary embodiment, connector 222 is configured to detachably connect to a hose through segments, where the hose extends through a tap nozzle such that the spray head 10 is coupled with fluidity at the tap. The hose may have a telescopic arrangement (for example, configuration, connection, etc.) in relation to the toecap. In other words, the connection allows the sprinkler head 210 to be detached from the tap and the hose
4818-2944-5929.1
14/39 removed from the toecap and also allows the hose to be retracted into the toecap and the spray head 210 to be attached to the tap.
[00076] The fluid directed into the inlet 223 flows to one or more outlets (for example, outlet members, etc.), which are generally located opposite to inlet 223. As shown in FIGS. 1 and 5, the spray head 210 includes a first outlet member 231, a second outlet member 232 and a third outlet member 233.
[00077] The first output member 231 is configured to provide a first spray function. FIGS. 27-30 illustrate an exemplary embodiment of the first outlet member 231 which includes a plurality of nozzles 231a having an annular arrangement and configured to direct the fluid to a first spray pattern. As shown, the first outlet member 231 includes a chamber 231b which is defined by an outer wall 231c and an inner wall 231d. Chamber 231b can be fluidly connected to valve 239 to receive fluid from it. The inner wall 231d can define a cavity 231e, which can be configured to receive another element of the spray head 210 thereon, such as the second outlet member 232. As shown in FIGS. 6, 29 and 30, the first outlet member 231 may also include one or more coupling features (shown in the form of tabs 231f) that are configured to couple the first outlet member 231 to valve 239, such as body 240. The flaps 231f can be resistant to deflect elastically during assembly and then engage openings in the body 240 to detachably couple the first outlet member 231 and valve 239 together. According to an exemplary embodiment, the plurality of nozzles 231a of the first outlet member 231 are configured to provide a spray pattern having a defined shape, such as a wedge-shaped spray pattern. The defined spray pattern can have a focal length (i.e., a distance from the spray head 210) over which the defined shape is focused. As a
4818-2944-5929.1
For example, the first output member 231 can be configured as shown and described in US Patent Application No. 13 / 359,089, which is incorporated by reference in this document in its entirety.
[00078] The second outlet member 232 is configured to provide a second spray function that is different from the first spray function of the first outlet member 231. According to an exemplary embodiment, the second outlet member 232 includes at least one nozzle 232a which is configured to provide an aerated stream of fluid from the spray head 210.
[00079] The third output member 233 is configured to provide a third spray function which is different from the first and second spray functions of the first and second output members 231 and 232. According to an exemplary embodiment, the third output member outlet 233 includes a plurality of nozzles that are configured to provide a fine and smooth spray, such as for cleaning fruit or other fragile objects. For example, the plurality of nozzles of the third outlet member 233 may provide substantially parallel currents or may provide an outward and parallel path current matrix in order to provide a no-flow intersection of fluid streams.
[00080] It is contemplated that any of the outlets (for example, outlet members 231, 232, 233) may have any of the features described above, or may have any other water function. In addition, the outlets may include orifices that may or may not include a nozzle coupled to or integrally formed in each orifice. The different outlets can be configured for or used for different purposes, for example, vessel filling, hand washing, dish washing, rinsing, potent washing, etc., which can be performed better with different spray patterns and / or pressures or flow speeds.
[00081] FIGS. 31-35 illustrate an exemplary embodiment of a third outlet assembly that includes a third outlet member
4818-2944-5929.1
16/39
233 having a plurality of nozzles 233a arranged in eight sets (e.g. groups) in an annular manner. As shown, each set includes about 41 nozzles 233a, however, the number of nozzles can be adapted. According to an exemplary embodiment, the third outlet member 233 is formed from a sheet (for example, a plate, a blank, etc.) of stainless steel having a thickness of about 0.008 inches (for example, 0.006-0.010 inches) and the plurality of nozzles 233a are etched (for example, chemically etched, photo-etched, etc.) such that each nozzle 233a has a diameter of about 0.012 inches (for example, 0.010-0.014 inches). According to another exemplary embodiment, each nozzle 233a is tapered, such that nozzle 233a has an outlet that is of a different size (for example, larger, smaller) than an inlet of nozzle 233a. For example, the outlet of the nozzle 233a can be about 0.012 inches, and the inlet of the nozzle 233a can be about 0.016 inches (for example, 0.014-0.018 inches).
[00082] When formed (for example, engraved), the third output member 233 is preferably flat. According to an exemplary embodiment, the third outlet assembly also includes an outer member 234 that is formed around the third outlet member 233. The outer member 234 can be made of any suitable material, such as a plastic (for example, resin, polymer, thermoset, thermoplastic, etc.) and can be done using any suitable method, such as injection molded. For example, the outer member 234 can be overmolded to the third outlet member 233 to form the third outlet assembly. According to an exemplary embodiment, during the formation of the outer member 234 (for example, during overmoulding), the third flat exit member 233 is reconfigured to a tapered trunk shape. As shown in FIGS. 6 and 34, an internal diameter of the outlet of the third cone-shaped outlet member 233 extends forward (that is, away from the inlet end and in
4818-2944-5929.1
17/39 towards the sprinkler end of the sprinkler head) in relation to an external diameter of the third outlet member 233. The truncated cone arrangement advantageously directs the fluid in a divergent manner, however, forming the nozzles of the third outlet member in the The plan allows for a more efficient and repeatable manufacturing process (eg easier, less expensive, etc.). Note that the third output member can be made of other suitable materials that are resistant to corrosion and capable of providing the functionality mentioned above.
[00083] External member 234 of the third output assembly can be configured to support other output members. As shown in FIG. 6, the first outlet member 231 is provided in an annular cavity of the outer member 234, and the second outlet member 232 is provided in an annular cavity of the first outlet member 231. In other words, the outlet members can have a nested arrangement in the sprinkler head housing 210. The outlet members may include features (for example, locking tabs) that are configured to secure the members to each other and or other elements of the sprinkler head 210, such as the housing 215 and / or body 240.
[00084] According to other exemplary modalities, the third outlet assembly can be configured to include one or more nozzle sets, where each set includes one or more nozzles. For example, as shown in the embodiment of Figure 44, the third outlet 433 is configured having four sets of nozzles, where each set includes eighty-one nozzles 433a for a total of three hundred and twenty-four nozzles. As shown, the third outlet member 433 of the third outlet assembly can include four sets of nozzles arranged in four quadrants on the surface of the third outlet member, where an outer row of nozzles includes twenty-eight nozzles 433a, the inner row includes twenty and six nozzles 433a and the intermediate row includes twenty-seven nozzles. O
4818-2944-5929.1
18/39 outlet member can be configured differently than what is shown, such as where each set of nozzles includes three rows of twenty-seven nozzles 433a. Each set or quadrant of the third output member may include eighty one nozzles 433a in this. Each nozzle can be configured as a hole (for example, hole, opening, etc.) with a generally uniform cross section (for example, shape, size, etc.) through outlet 433. As shown in FIG. 44A, each nozzle 433a is configured having a conical-trunk shape, where the size of the inlet passage (for example, the cross-sectional area of the nozzle 433a on the inner surface 433c of outlet 433) is smaller than the size of the outlet passage (for example, the cross sectional area of the nozzle 433a on the outer surface 433b of the outlet). According to yet another example, the inlet passage has a larger size (e.g., cross-sectional area) than the outlet passage of the nozzle 433a.
[00085] As shown in FIG. 1, the sprinkler head 210 includes a first actuator 224 (e.g., button, switch, lever, etc.) and a second actuator 225. The first and second actuators 224, 225 are configured to control the operation of valve 239 to change (for example, toggle) the operation of the spray head 210 between its one or more functions. According to an exemplary embodiment, the first actuator 224 is configured as a button configured to move between a first position (for example, a non-lowered position) and a second position (for example, a lowered position). FIG. 7 illustrates the first actuator 224 in the second position. When the first actuator 224 is in the first position, the sprinkler head valve 239 directs the fluid to the second outlet member 232 or the third outlet member 233. When the first actuator 224 is lowered from the first position to the second position, valve 239 redirects fluid to the first outlet member 231. As shown, the first
4818-2944-5929.1
19/39 actuator 224 is movable in a radial direction R that is transversal to the longitudinal direction L.
[00086] As discussed in more detail below, the spray head 210 may include a redirect member that is configured to redirect the first actuator 224 (for example, such as via a redirector). For example, the redirect member can redirect the first actuator 224 in a direction from the second position to the first position. This arrangement can advantageously configure the first actuator 224 as a momentary switch, where the button must be kept in the lowered position (for example, the second position), in order to maintain the alternative spray pattern (for example, the first spray pattern ). Once the pressure lowering the first actuator 224 is released, the redirect force will move the first actuator 224 to the non-lowered position, and the spray head 210 will change the function (for example, moving away from the first spray pattern) .
[00087] The second actuator 225 can be configured to move between a first position, in which the fluid is directed to either the second outlet member 232 or the third outlet member 233 and a second position, in which the fluid is directed to another outgoing member. According to an exemplary embodiment, the second actuator 225 is configured as a lever that rotates between a first position (for example, a forward position) and a second position (for example, a backward position). The forward position of the second actuator 225 may correspond to when a front portion 225 of the second actuator 225 is lowered towards the sprinkler (for example, in the direction of the longitudinal axis L) and when a rear portion 225b of the second actuator 225 extends to away from the sprinkler or the longitudinal axis L (see FIG. 7). The back position of the second actuator 225 may correspond to when the rear portion 225b is lowered towards the sprinkler on the shaft
4818-2944-5929.1
20/39 longitudinal L and the front portion 225a is extended away from the sprinkler or longitudinal axis L. FIG. 7 illustrates the second actuator 225 in the backward position. The second actuator 225 can be pivotally coupled to valve 239 and / or another element of the spray head, such as a housing. As shown, the second actuator 225 is pivotally coupled to a pivot P of the body 240.
[00088] According to an exemplary embodiment, when the second actuator 225 is in the first position, the fluid is directed to the second outlet member 232, and when the second actuator 225 is in the second position, the fluid is directed to the third outlet member 233. Thus, a user of the spray head 210 can switch between the second and third spray functions by moving (for example, switching) the second actuator 225 between its first and second positions.
[00089] The spray head 210 can optionally include a housing 215 (e.g., a liner, etc.) that is configured to house one or more elements of the spray head 210. As indicated in FIG. 6, housing 215 includes an outer wall having a first portion 215a and a second portion 215b, which store and surround at least a portion of valve 239. In other words, the outer wall of housing 215 defines a cavity (e.g., chamber , etc.) to receive at least a portion of valve 239 therein. The outer wall may include an opening therein. As shown, the outer wall of housing 215 includes a first opening 215c arranged at a first end (e.g., an inlet end) of housing 215 adjacent to first portion 215a and also includes a second opening 215d arranged at a second end (for example, example, an outlet end) of housing 215 adjacent to second portion 215b. A spray head portion 210, such as connector 222 and / or valve 239, is configured to extend through the first opening 215c. The one or more outgoing members can be
4818-2944-5929.1
21/39 arranged in the second opening 215d. As shown, the first outlet member 231, the second outlet member 232 and the third outlet member 233 are arranged in the second opening 215d of housing 215, such that the fluid directed from the outlet members is discharged from the second end of the housing 215 having the second opening 215d.
[00090] Housing 215 may include one or more of a feature configured to couple and / or secure another element of the spray head 210 to the housing. For example, housing 215 may include a feature, such as segments, that the third outlet assembly removably couples (for example, removably, selectively, etc.) to them. As shown in the exemplary embodiment of FIG. 6, the outer member 234 of the third outlet assembly includes outer segments that mate with inner segments of the outer wall (e.g., second portion 215b) of housing 215 to detachably couple the third outlet assembly to housing 215. This arrangement it advantageously allows the third outlet assembly (for example, together with the third outlet member 233) to be removed, such as for cleaning purposes. This is particularly advantageous for the embodiment of the third outlet member 233 having nozzles 233a of 0.012 inches in diameter, since the nozzles can become clogged with debris due to their relatively small size, which provide for gentle spraying. Also, for example, housing 215 may include a feature that facilitates coupling of valve 239 to housing 215.
[00091] Housing 215 may additionally include one or more additional openings, such as, for example, for receiving one or more actuators to control the operation of the spray head 210. As shown in FIGS. 1-3, housing 215 includes a third opening 215e that is configured to receive the first actuator 224 and
4818-2944-5929.1
22/39 a fourth opening 215f that is configured to receive the second actuator 225. The third opening 215e may have a generally circular cross-sectional shape to define a cylindrical hole in the housing 215 to receive the first actuator 224, or may have any shape suitable that is adapted to the shape of the first actuator 224. The fourth opening 215f may have a generally elongated cross-sectional shape (e.g., elliptical, grooved, etc.) to define a hole in housing 215 that has a corresponding shape as the second actuator 225, or can have any suitable shape that is adapted to the shape of the second actuator 225.
[00092] As shown in FIGS. 3, 6 and 7, valve 239 (e.g., fluid regulating valve) includes a body 240 (e.g., a valve body). FIGS. 18 and 19 illustrate an exemplary embodiment of body 240. Body 240 includes an inlet that is configured to receive a supply of fluid. According to an example, the entrance of the body 240 is entrance 223 of the spray head 210. For this example, the connector 222 can optionally be formed integrally with the body 240. According to another example, the entrance of the body 240 it is formed separately from the inlet 223 (and / or the connector 222) of the spray head 210. For this example, the inlet of the body 240 can be in fluid communication with (for example, fluidly connected to) inlet 223.
[00093] Valve 239 can also include one or more of a chamber that is configured to receive fluid. As shown in FIGS. 6 and 7, body 240 of valve 239 includes a first chamber 241, a second chamber 242 and a third chamber 243, where each chamber is configured to selectively receive fluid depending on the operation mode of the spray head 210 (e.g. the valve arrangement 239). The one or more chambers can be defined by body 240,
4818-2944-5929.1
23/39 alone or in combination with other spray head elements 210.
[00094] Body 240 may include one or more portions. As shown in FIGS. 18 and 19, the body 240 includes a first portion 240a and a second portion 240b, which can be integrally formed together or formed separately, then coupled together. As shown, the first portion 240a is the entry end of the body 240 and the second portion 240b is the exit end of the body 240.
[00095] FIGS. 20 and 21 illustrate an exemplary embodiment of a second portion 240b of body 240. The second portion 240b can be configured to include one or more members in circular, elliptical, and / or other properly shaped shapes (e.g., sections, walls, etc. .) to help define one or more chambers of valve 239. As shown, the second portion 240b includes a circular shaped inlet 240e, a first elliptical section 240f which is provided around inlet 240e and extends from a base 240g away from entry 240e, a second elliptical section 240h provided around and extending from the first elliptical section 240f away from entry 240e and a first circular section 240i provided around and extending from the second elliptical section 240h away from entrance 240e. The first elliptical section 240f may have a major axis that extends in the radial direction R and a minor axis that extends in a second direction that is transversal to the radial direction. The first elliptical section 240f can help define the second chamber 242, such as together with the base 240e and the first portion 240a. The second elliptical section 240h can have a main axis that extends in the second (transverse) direction of the minor axis of the first elliptical section 240f and a minor axis that extends in the radial direction R. The second elliptical section 240h can help define the second portion 241b of the first chamber 241, either alone or in combination with the first elliptical section 240f. The first circular section 240i can have a main axis
4818-2944-5929.1
24/39 that extends in the radial direction R and a smaller axis that extends in a second (transverse) direction. The first circular section 240i can help define the third chamber 243, either alone or in combination with the second elliptical section 240h. According to the example shown, the second portion 240b includes the pivot P, on which the second actuator 225 is configured to rotate.
[00096] FIGS. 22-26 illustrate an exemplary embodiment of the first portion 240a of the body 240. The first portion 240a can be configured to include one or more members in circular, elliptical, and / or other properly shaped shapes (e.g., sections, walls, etc.). ) to help define one or more chambers of valve 239. For example, first portion 240a may include members that help define inlet 223, connector 222, first chamber 241 (for example, first portion 241a, second portion 241b), second chamber 242, and / or third chamber 243. As shown, the first portion 240a includes a second circular section 240j that helps define the third chamber, 243, a first elliptical section 240k that helps to define the second chamber 242 and a second elliptical section 240m which helps to define the second portion 241b of the first chamber 241. For example, the second chamber 242 can be defined by the first elliptical section 240k in combination with the second circular section 240j. Also, for example, each second portion 241b can be defined by the second elliptical section 240m in combination with the first elliptical section 240k and / or the second circular section 240j.
[00097] The first elliptical section 240k can have a main axis that extends in the radial direction R and a smaller axis that extends in a second transversal direction. The second circular section 240j can be contained, for example, in the first elliptical section 240k, such that a portion or all of the second circular section 240j is provided within the first elliptical section 240k, as shown in FIGS. 23 and 25. Alternatively, the first elliptical section 240k and the second circular section 240j can
4818-2944-5929.1
25/39 overlap each other. The second elliptical section 240m can have a main axis that extends in the second transverse direction and a minor axis that extends in the radial direction R. The plurality of elliptical sections of the body 240 can advantageously allow the body 240 to include multiple chambers, which provide fluid for multiple outlets, in a relatively small size (eg cross section). Thus, the spray head 210 can provide multiple spray functions and still be relatively compact in size.
[00098] Valve 239 can also include one or more of a redirector (for example, redirect piston, piston, valve stem, etc.). As shown in FIGS. 6 and 7, valve 239 includes a first redirector 251 and a second redirector 252, where the first and second redirectors 251, 252 are movable within the body
240 to control the flow of fluid between the first, second and third chambers 241, 242, 243.
[00099] According to an exemplary embodiment, the first redirector 251 is movable between a first position (for example, up position, non-lowered position) and a second position (for example, down position, lowered position). FIG. 7 illustrates the first redirector 251 in the second position. When the first redirector 251 is in the second position, the first chamber 241 is fluidly connected to the inlet 223 and the second chamber 242 is fluidly disconnected from the inlet 223, such that the fluid flow is directed from the inlet 223 to the first chamber 241. Consequently, no fluid is directed to the second chamber 242 when the first redirector 251 is in the second position. When the first redirector 251 is in the first position, the second chamber 242 is seamlessly connected to input 223 and the first chamber
241 is fluidly disconnected from inlet 223, such that the flow of fluid is directed from inlet 223 to the second chamber 242.
4818-2944-5929.1
26/39
Consequently, no fluid is directed to the first chamber 241 when the first redirector 251 is in the first position.
[000100] As shown in FIG. 7, the first actuator 224 is configured to move (for example, slide, transfer, etc.) the first redirector 251 along direction R between its first and second positions when actuated (for example, lowered) by a user of the head. sprinkler 210. Thus, a portion of the first redirector 251 can be coupled directly (or indirectly through another element of the sprinkler head 210) to the first actuator 224, such that the movement of the first actuator 224 results in a corresponding movement of the first redirector 251. For example, a first end 251a of the first redirector 251 can be coupled to the first actuator 224. The first actuator 224 can move relative to, for example, housing 215.
[000101] FIGS. 40-43 illustrate an exemplary embodiment of the first redirector 251. The first redirector 251 includes the first end 251a, a second end 251b, and a sealing portion 251c, which can be provided between the first and second ends 251a, 251b. As indicated in FIG. 7, the sealing portion 251c is configured to provide a seal between the first redirector 251 and a portion of the valve 239 (e.g., a portion of the body 240) to prevent fluid from passing beyond the seal. For example, the sealing portion 251c can seal (e.g., fluidly disconnect) the second chamber 242 to prevent fluid from passing from inlet 223 to the second chamber 242 when the first redirector 251 is configured in the second position. Also, for example, the sealing portion 251c can seal the first chamber 241 to prevent fluid from passing from inlet 223 to the first chamber 241 when the first redirector 251 is configured in the first position.
4818-2944-5929.1
27/39 [000102] As shown in FIGS. 40-43, the first redirector 251 is generally configured as a piston (for example, it has a piston shape). The first end 251a may have a generally cylindrical shape, which may include a feature, such as a lower cut section 251e (e.g., recess, channel, etc.) that is configured to receive a portion of the first actuator 224 to couple the first redirector 251 and the first actuator 224 together. The first actuator 224 can include a flexible retaining member that expands when moving over the non-lower portion of the first end 251a, then fits into a mechanical locking arrangement with the lower cut when the retaining member engage the bottom cut. The second end 251b can be generally cylindrical in shape, tapered in shape or any suitable shape. The sealing portion 251c may have a generally cylindrical shape which is disposed closest to the second end 251b. However, it is noted that the shape of the first redirector 251, as well as the location of the sealing portion 251c, can be adapted to the geometry of valve 239 (e.g., body 240). The sealing portion 251c can include a raised portion (e.g., one extending outwardly) with respect to the second end 251b (and / or first end 251a). As shown in FIGS. 42 and 43, the sealing portion 251c is configured as a shoulder extending away from the second end 251b. The sealing portion 251c can optionally include a channel 251d (e.g., recessed portion) configured to receive a sealing member (e.g., a seal, an O-ring, etc.). As shown, channel 251d is embedded in the shoulder of the sealing portion 251c, such that the sealing portion 251c has a generally C-shaped cross section for receiving the sealing member 271 in the form of an O-ring in the channel 251d . For the modality including the sealing member 271, the sealing member 271 can either alone or in cooperation
4818-2944-5929.1
28/39 with the sealing portion 251c, fluidly disconnect the first chamber 241 or the second chamber 242 from the inlet 223, depending on the position of the first redirector. In other words, when the first redirector 251 is in the second position, the second chamber 242 can be fluidly disconnected from the inlet 223 by the sealing member 271 and the first redirector 251; and when the first redirector 251 is in the first position, the first chamber 241 can be fluidly disconnected from the inlet 223 by the sealing member 271 and the first redirector 251.
[000103] Valve 239 can optionally include a redirect member that is configured to redirect the first redirector 251 in one direction. As shown in FIGS. 7 and 42, the redirect member 245 is in the form of a coil spring (for example, a helical spring, a compression spring, an extension spring, etc.) configured to redirect the first redirector 251 from the second position ( for example, the user's lowered position) towards the first position (for example, the pre-user's lowered position). In this arrangement, a force of the redirecting member can advantageously be in an opposite (for example, opposite) direction to that of the user's force by lowering the first actuator 224. When the user lowers the first actuator 224, as for the second position, the redirect member 245 is compressed, thereby storing energy. When the user releases the force by lowering the first actuator 224, the redirect member 245 exerts a force from the stored energy to return the first actuator 224 to the first position.
[000104] The redirect member 245 may have a first portion (for example, a first end) that engages the first redirector 251 and a second portion (for example, a second end) that involves a portion of another valve element 239 for give a redirect force between the first
4818-2944-5929.1
29/39 redirector 251 and the other element. As shown, the second end 251b of the first redirector 251 includes a hole 251f that receives a pillar 240c from the body 240 with the redirecting member 245 disposed in the hole 251f between the pillar 240c and the second end 251b of the first redirector 251. The hole 251f it can have a generally cylindrical shape, according to an example, for receiving and retaining the redirect member 245 in the form of a coil spring. The pillar 240c can be arranged in the first portion 240a of the body 240 and can have a generally cylindrical shape, according to an example. The pillar 240c can also help guide the movement of the first redirector 251, for example, by maintaining the position (for example, the radial position, etc.) of the first redirector 251 in relation to the body 240 as the first redirector 251 moves between the first and second positions in the radial direction. This arrangement can advantageously help the first redirector 251 to provide a good and reproducible seal with the body 240.
[000105] Also shown in FIG. 7, the first chamber 241 includes a first portion 241a that receives at least a portion of the first redirector 251. The first portion 241a can be configured to extend in the radial direction R (which can be transverse to the longitudinal direction L), such that the first redirector 251 moves in the radial direction R within the first portion 241a between the first and second positions. The first section 241 may additionally include a second portion 241b that is fluidly connected to an outlet (e.g., an outlet member). As shown in FIG. 6, the second portion 241b is fluidly connected to the first outlet member 231, such that fluid passing through the first chamber 241 exits the spray head 210 through the plurality of nozzles 231a of the first outlet member 231. It is also shown that the spray head 210 can include two second parallel portions
4818-2944-5929.1
30/39
241b, wherein each second portion 241b extends along one of the two opposite sides of the body 240. Each second portion 241b can be configured to extend at an angle to the first portion 241a. For example, each second portion 241b may extend in a transverse direction (for example, the longitudinal direction) with respect to the first portion extending radially 241a.
[000106] Valve 239 can optionally include additional elements (e.g., components, members, etc.) to help retain the first redirector 251 and / or seal the first chamber 241. As shown in FIGS. 7-10, valve 239 includes a support sleeve 246 and retaining member 247.
[000107] The support sleeve 246 can be arranged in the first portion 241a of the first chamber 241 to support the first redirector 251, as during its movement. The support sleeve 246 may include an outer wall 246a that is shaped to complement the shape of the body 240 (for example, its walls defining the first portion 241a) to maintain the relative position between the support sleeve 246 and the body 240. A outer wall 246a can include one or more of a channel that is configured to receive a corresponding number of sealing members itself. As shown in FIG. 9, the outer wall 246a includes two generally displaced C-shaped channels (for example, in cross section) 246c configured to receive the sealing members 272, 273 to provide seals between the support sleeve 246 and the body 240. The wall outer 246a includes one or more openings 246d, such as one or two pairs of opposing openings, which allow fluid to flow from the first portion 241a to the second portion 241b of the first chamber 241. The support sleeve 246 also includes an inner wall 246b which extends internally from the outer wall 246a and is configured to help maintain the position (e.g., concentricity) of the first redirector 251 (e.g., one end of itself) in
4818-2944-5929.1
31/39 with respect to body 240. The inner wall 264b may include an opening defining an inner surface, which may contact an outer surface of the first redirector 251 to maintain the relative position of the redirector and act as a guide for the redirector during your movement.
[000108] Retention member 247 can be configured to retain other elements (for example, support member 246) in place at valve 239. As shown in FIGS. 7 and 10, the retaining member 247 includes an upper wall 247a and a lower wall 247b. The upper wall 247a can be configured to engage the body 240, such as a channel (as shown in FIG. 7) of the first portion 240a, to hold the retaining member 247 in place in relation to the body 240. The upper wall 247a and / or the bottom wall 247b can be configured to hold the support member 246 in place, as it contacts a portion of the support member 246 to prevent the support member 246 from leaving the first chamber 241. The bottom wall 247b can extend away from the upper wall 247a towards the support member 246 and include an opening therein through which a portion of the first redirector 251 can pass through. Thus, the bottom wall 247b includes an internal surface that is configured to support the first redirector 251, such as through an abutment arrangement. A cavity can be formed between the inner wall 246b of the support member 246, the lower wall 247b of the retaining member 247 and the first redirector 251, wherein the cavity receives the sealing member 274 to form a seal between these head elements sprinkler 210.
[000109] According to an exemplary embodiment, the second inverter 252 is movable between a first position and a second position. FIG. 7 illustrates the second redirector 252 in the second position (e.g., forward position, leftward position). In the first position, the second redirector 252 is in the right side position or
4818-2944-5929.1
32/39 to the rear (that is, where it is moved from left to right in FIG. 7 When the second redirector 252 is in the second position, the third chamber 243 is fluidly connected (for example, in fluid communication with) to the second chamber 242, such that the fluid flow is directed from the second chamber 242 to the third chamber 243. When the second redirector 252 is in the first position, the third chamber 243 is fluidly disconnected from the second chamber 242, such that none fluid is directed to the third chamber 243 from the second chamber 242. For example, the second outlet member 232 (or a chamber leading to it) may be fluidly connected to the second chamber 242, when the second redirector 252 is in your first position.
[000110] As shown in FIGS. 6 and 7, when the second redirector 252 is in the second position, the fluid flows from the second chamber 242 through the third chamber 243 to the third outlet member 233 to provide the third spray function (for example, operating mode) spray head 210. Thus, the plurality of nozzles 233a of the third outlet member 233 are fluidly connected to the third chamber 243 in this configuration. When the second redirector 252 is in the first position, fluid flows from the second chamber 242 to the second outlet member 232 to provide a second spray function of the spray head 210. Thus, at least one nozzle 232a of the second spray member output 232 is fluidly connected to second chamber 242 in this configuration. The second chamber 242 can include more than one portion. For example, the second chamber 242 can include a first portion fluidly connected to the inlet 223, such as when the first redirector 251 is in the second position and can also include a second portion that is fluidly connected to the first portion of the second chamber 242, such as when the second redirector 252 is in the
4818-2944-5929.1
33/39 first position. The second portion of the second chamber 242, if provided, can be fluidly connected to the second outlet member 232. According to an exemplary embodiment, the second outlet member 232 can be aligned with the second redirector 252 and therefore aligned with the third chamber 243. For this example, the second portion of the second chamber 242 can be provided between the second outlet member 232 and the second redirector 252. The second portion of the second chamber 242, as described above, can alternatively be configured as a routing chamber for the second outlet member 232, which fluidly connects to the second chamber 242 and the second outlet member 232, such as when the second redirector 252 is in its first position.
[000111] As shown in FIGS. 6 and 7, the second redirector 252 is configured to move within the body 240 in the longitudinal direction L between the first and second positions. For example, at least a portion of the second redirector 252 can be arranged in a portion of the third chamber 243, such that the second redirector 252 moves in the longitudinal direction L within the portion of the third chamber 243. Actuation of the second actuator 225 between its positions moves the second redirector 252. For example, a sliding member 235 can be operatively coupled to the second redirector 252 and the second actuator 225, so that the actuation of the second actuator 225 moves (e.g., slides, translates, etc.) the member slide 235 and in turn moves the second redirector 252 between the first and second positions.
[000112] FIGS. 36-39 illustrate an exemplary embodiment of the second redirector 252. FIG. 36 also illustrates optional sealing members 275, 276, together with the second redirector 252, which can help to form a seal between the second redirector 252 and the body 240. The second redirector 252 includes a first end 252a, a second end 252b and a portion
4818-2944-5929.1
34/39 seal 252c. As shown in FIGS. 6 and 7, the sealing portion 252c is configured to provide a seal between the second redirector 252 and a portion of the valve 239 (e.g., a portion of the body 240) to prevent liquid from passing beyond the seal. For example, the sealing portion 252c can seal the second outlet member 232 of the second chamber 242 to prevent fluid from passing from the second chamber 242 to the second outlet member 232 when the second redirector 252 is in the second position. Also, for example, the sealing portion 252c can seal the third chamber 243 of the second chamber 242 to prevent fluid from passing from the second chamber 242 to the third chamber 243 when the second redirector 252 is in the first position.
[000113] As shown in FIGS. 36-39, the second redirector 252 is generally configured as a piston (for example, it has a piston shape), with the sealing portion 252c extending away from a body 252d. The sealing portion 252c is arranged at the second end 252b of the second redirector 252 in the example shown. However, the sealing portion 252c can be provided anywhere along the body 252d between the first and the second end 252a, 252b. The seal portion 252c is generally cylindrical in shape, tapered in shape or any suitable shape that can be adapted to the geometry of valve 239 (e.g., body 240). As shown in FIGS. 37 and 39, the seal portion 252c is configured as a shoulder extending away from the body 252d, which may include an optional channel 252e provided therein. The channel 252e can be embedded in the shoulder of the sealing portion 252c, such that the sealing portion 252c has a cross section generally C-shaped to receive the sealing member 275 in the form of an O-ring in the channel 252e. Thus, sides of the sealing portion 252c hold sealing member 275 in channel 252e. For the configuration, including the member of
4818-2944-5929.1
35/39 seal 275, the seal member 275 can, either alone or in cooperation with the seal portion 252c, fluidly disconnect the third chamber 243 or the second outlet member 232 from the second chamber 242, depending on the position of the second redirector 252.
[000114] The second redirector 252 may include one or more additional channels 252f configured to receive one or more additional sealing members 276. Also shown in FIGS. 37 and 39, the second redirector includes a second channel 252f provided along the body 252d at a distance that extends beyond the third chamber 243 to provide a seal between the second redirector 252 and the body 240 on the upstream side of the third chamber 243 (See Fig. 7, showing the sealing member 276 provided outside the third chamber 243).
[000115] The second redirector 252 can include an opening 252g that is configured to receive a portion of the slider 235 itself to operatively couple the second redirector 252 and the slider member 235. As shown in FIGS. 36 and 37, the opening of 252g is arranged at the first end 252a of the second redirector 252 and is generally cylindrical in shape (for example, having a circular cross-sectional shape). However, the shape and location of opening 252g can be adapted to the shape and location of sliding member 235 and / or valve 239 in general.
[000116] The body portion 252d provided adjacent the third chamber 243 can be configured to have a shape that allows fluid to pass from the second chamber 242 to the third chamber 243 when the second redirector 252 is in the second position. As shown in FIG. 38, body 252d includes a plurality of radial ribs extending 252h (e.g., members, sections, etc.) having open spaces 252i between each pair of adjacent ribs 252h. This arrangement advantageously allows fluid to flow through the open spaces 252i to the third chamber 243 when the second redirector 252 is in the
4818-2944-5929.1
36/39 second position, providing resistance and stability during movement, since the ends of the ribs 252h can be guided by portions of the body 240. FIGS. 13 and 14 show opposing guide portions 240d of body 240 that guide the ends of the counter ribs 252h, as well as the fluid connection between open spaces 252i and the third chamber 243. As shown, body 240 may include an open section around of the body (for example, along the longitudinal axis L) 252d of the second redirector 252, such that all open spaces 252i are fluidly connected to the third chamber 243. As shown in FIG. 15, the body 240 can also include a closed section around the body 252d of the second redirector 252, such that all ends of the ribs 252h are supported by an internal surface of the body 240. Thus, the open and closed sections are provided in different along the longitudinal axis L.
[000117] FIGS. 11-17 illustrate various views in cross sections to further illustrate the flow of fluid through the spray head 210, such as body 240. FIG. 11 shows the second portions 241b of the first chamber 241. FIG. 12 shows the second chamber 242, as well as the open spaces 252i fluidly connected to the third chamber 243. FIG. 16 shows the second portions 241b of the first chamber 241, the second chamber, 242, the third chamber 243, the first redirector 251, the second redirector 252 and the body 240. FIG. 17 shows the first, second and third outgoing members, 231, 232, 233, as well as the second and third chambers 242, 243.
[000118] The sprinkler head 210 can optionally include a screen member 281 disposed at the inlet 223 to filter out any debris or sediment, which can pass to the inlet 223 of the sprinkler head 210. As shown in FIG. 6, screen member 281 can be arranged at entry 223. Screen member 281 can be a mesh screen that is configured to a predetermined size (e.g.
4818-2944-5929.1
37/39 orifice, porosity, etc.). A flow control 282 (e.g., collar) can optionally be provided adjacent to screen member 281. Flow control 282 and / or screen member 281 can couple to sprinkler head 210, as well as body 240. For example, For example, the inner surface of the body 240 defining the inlet 223 may include a stop member (e.g., raised member) that removably protects the screen member 281 and 282 in place of the flow control at the inlet 223.
[000119] Sprinkler head 210 can optionally include additional sealing members 277 to provide additional seals on valve 239 and / or sprinkler head 210. For example, one or more sealing members 277 can be provided between the first portion 240a and the second portion 240b of the body 240. Also, for example, one or more sealing members 277 can be provided between the second portion 240b of the body 240 and the outlet members, such as the first outlet member 231 and the third member output 233.
