    The control valve has a valve housing (14) with a main valve passage (20). A flow control assembly (10) is positioned within the main valve passage (20) and comprises a fixed, first control element (26) and a second control element (28) which is rotatable relative to the first control element (26). The fixed, first control element (26) has passages (128, 130, 132, 134), the rotatable, second control element (28) has openings (138, 140, 142, 144). Different volume flows can be achieved by rotating the second control element (28) with respect to the first control element (26). If no opening (138-144) of the rotatable second control element (28) overlaps with a passage (128-134) of the first fixed one, the control valve is closed. From the closed position, the second control element (28) can be rotated into several positions in which more and more passages (128-134) and openings (138-144) overlap, so that an ever increasing volume flow is realized.

    GENERAL PRIOR ART
    1. Technical field
    The present disclosure relates generally to flow control devices and, more particularly, to a rotationally controlled valve (e.g., a throttle) to selectively and gradually control the flow of fluid through a valve.
    2. Description of the prior art
    In the prior art, a currently known control valve includes a cone or a spindle that is linearly displaced during normal operation of the valve. Within these valves, which are often referred to as linear displacement valves, the cone is arranged and movable in a disk stack or valve cage which defines a plurality of convoluted and / or non-convoluted fluid passages. The valve set of these valves has the combination of cone and valve cage. Certain linear displacement valves are designed for "flow across the cone, with fluid flowing radially inward from the outside of the valve body into the interior of the valve body, the fluid being subjected to a pressure drop due to the flow through the passages of the valve cage. In this arrangement, the valve is opened by lifting the cone from a seat ring, as a result of which the fluid can flow out of the valve from the inside of the valve basket via the released seat ring. Conversely, movement of the seating surface of the cone in tight engagement with the complementary seating surface of the seat ring facilitates a closed or locked state for the valve.
    As an alternative to a flow over the cone, other linear displacement valves are designed for a "flow under the cone, with fluid flowing axially upwards into the interior of the valve body to the outside thereof, the fluid resulting
    1/46 scanned the flow of fluid radially outward through the 09/01/2020
    Fluid passages of the valve cage is subjected to a pressure drop. In this arrangement, the valve is opened by lifting the cone from the aforementioned seat ring, allowing the fluid to flow into the interior of the valve body and then radially outward through the fluid passages of the valve body. Conversely, movement of the seating surface of the cone in tight engagement with the complementary seating surface of the seat ring facilitates a closed or locked state for the valve.
    Linear displacement control valves are commonly used to control flow and pressure in a process. However, such control valves have certain shortcomings that reduce their overall usability. For example, linear movement of the valve stem can result in volatile emissions, particularly in high pressure fluid environments and when the stem is subject to reciprocating motions. In these cases, volatile emissions in chokes are often difficult due to the high pressures and the reciprocation of the stem by the assembly.
    To avoid the aforementioned shortcomings of linear displacement control valves, rotary vane throttles are sometimes used in given applications. However, rotary vane throttles currently available on the market are single-stage devices. These single-stage devices absorb the pressure drop at one stage, creating high-speed jets that erode the disks and housings. They also have a problem with low openings where a sideways jet is created that can erode various parts of the housings and can cause wall erosion where fluid is released to the atmosphere. Other single-stage rotary valve throttles cannot provide a labeled KV versus rotation curve with variable levels of pressure reduction stages at any level. Other disc throttles, such as 1/4 turn, typically use 2 holes on the top disc and 2 holes on the bottom disc, which are exposed simultaneously, and thus have the ability to have fine control.
    Accordingly, there is a need in the prior art
    2/46
    Scanned 09/01 / Σ0Σ0 a fluid control valve that selectively opens and closes the valve while avoiding the aforementioned shortcomings when using existing linear displacement mechanisms and
    Rotary throttle washers. Various aspects of the present disclosure address this particular need, as discussed in more detail below.
    SUMMARY
    In general, the present disclosure relates to a new product (referred to herein as a control valve, throttle valve, or throttle) that uses a rotating upper disc to expose DRAG® passages on a fixed lower disc. One of the unique features of the present disclosure is the ability to gradually open different numbers of passages and to more carefully control exposure to increased flow. It can be implemented in tungsten carbide materials for eroding performance, or in metal for more conventional control valve applications. The flow can be embedded in the upper turntable in a housing configuration, one
    Angular seat configuration or an angular configuration occur. One of the fundamental innovations of the present disclosure is thus the creation of a DRAG® valve in the form of a turntable. While turntable devices are common in a single-stage pressure release form, the present disclosure provides a multi-stage, multi-way DRAG® form of the turntable construction, where, as noted above, the throttle can have an embedded, angled, or angled configuration and allows the fluid flow to flow in the upper turntable enters. The upper turntable has inlets that have been shaped to allow the overlap of flow passages that are in the lower fixed disk when the upper threshing disk is rotated. The passages in the lower fixed disc can be disclosed in rings or sleeves, each ring disclosing flow passages that can have a different number of DRAG® stages. The lower fixed disc houses the DRAG® passageways, which can be arranged in different ways to optimize the overall size of the unit. The shape of the
    3/46
    Scanned 09/01/2020
    Passages of the upper turntable underlie the spacing and diameter of the passages of the lower fixed disc and allow further flow through the passages of the lower disc when new ring passages are exposed. The property or number of steps per ring, the number of rings and the diameter of the passages can be set based on capacity and rating requirements. The geometry of the passageways can also be adjusted to create different opening properties for each passageway. The upper turntable can be moved by manual operation of a handle or the handle can be moved by a rotary actuator and a linkage assembly.
    The valve design thus effectively uses DRAG® multi-stage passages instead of the single-stage, lower, fixed disc. The pressure drop is therefore taken over more stages of pressure reduction, thereby reducing the fluid velocity and erosion rate and therefore increasing the life of the valve. In this regard, the present disclosure provides a valve construction that is a 1/4 turn device that is more effective in testing fugitive emissions because the stem does not move in and out of the assembly and only rotates. For example, the valve constructed in accordance with the present disclosure may provide 6 levels with low openings, 4 levels with medium openings, and 2 levels with fully open openings. All levels of the multi-tier arrangement would be gradually exposed, and with the openings fully open, all passageways would remain open. Thus, the present disclosure provides a multi-stage, multi-way rotary slide valve that is easily distinguishable from other single-stage designs. This enables the valve to be constructed with less expensive pressure relief components and seals and also significantly reduces the number of components.
    Specifically, according to an embodiment of the present disclosure, there is provided a control valve or throttle valve having a valve housing with a main valve passage. A flow control element is positioned within the main valve passage, the
    4/46
    Scanned 09/01 / Z0Z0
    Flow control element has a passage of the first stage and a passage of the second stage. A turntable is positioned in the main valve passage adjacent to the flow control element, the turntable having an opening of the first stage and an opening of the second stage. The turntable can be switched with respect to the flow control element between a closed position, a first position and a second position. In the closed position, the first stage opening and the second stage opening are not aligned with the first stage passage and the second stage passage, respectively, so the turntable blocks the first stage passage and the second stage passage by one This will prevent fluid flow. In the first position, the opening of the first stage is aligned with the passage of the first stage and the opening of the second stage is not aligned with the passage of the second stage, so that the turntable allows fluid flow through the passage of the first stage and the passage of the second stage blocked to prevent fluid flow. In the second position, the opening of the first stage is aligned with the passage of the first stage and the opening of the second stage is aligned with the passage of the second stage so that the turntable fluid flows through both the passage of the first stage and the passage of the second stage.
    The flow control element may include a plurality of first stage passages and the turntable may include a plurality of first stage openings, each opening of the first stage being associated with a respective one of the plurality of first stage passages. The flow control element may include a plurality of second stage passages and the turntable may include a plurality of second stage openings, each second stage opening being associated with a respective one of the plurality of second stage passages. The plurality of first stage openings may extend along a path spaced apart from a central axis by a first radial distance, and the plurality of second stage openings may extend along a path spaced apart from the central axis by a second radial distance that differs from the first radial distance.

    The flow control element may include a central body and at least one sleeve that extends around the central body, the sleeve and the central body together defining the passage of the first stage and the passage of the second stage. The flow control element may include multiple sleeves nested in relation to one another. The passage of the first stage can be defined jointly by the central body and one of the plurality of sleeves and the passage of the second stage can be jointly defined by adjacent sleeves of the plurality of sleeves.
    The flow control element may include multiple stacked disks that together define the passage of the first stage and the passage of the second stage.
    According to a further embodiment, the control valve or throttle valve includes a valve housing with a main valve passage. A flow control assembly is positioned in the main valve passage and includes a first control element and a second control element that is rotatable with respect to the first control element between a closed position, a first position, and a second position. In the closed position, the first and second control elements form a cone that prevents fluid flow through the main valve passage. In the first position, the first and second control elements jointly define a first control passage and, in the second position, the first and second control elements jointly define the first control passage and a second control passage.
    The flow control assembly may define multiple first control passes when the second control element is in the first position. The flow control assembly may define multiple second control passes when the second control element is in the second position.
    The first control element of the flow control assembly may include a central body and at least one sleeve that extends around the central body, and wherein the sleeve and the central body together define at least a portion of the first control passage and the second control passage. The first control element can include several stacked disks.

    According to various aspects of the present disclosure, a fluid control device for multi-stage fluid pressure control is provided. The fluid control device includes
    8/46
    Scanned 09/01/2020 fixed control element with several levels of passages formed therein and a rotatable control element with several levels of inlet openings formed therein, each of which is assigned to one of the passages. The rotatable control member is rotatable with respect to the fixed control member to selectively move the inlet ports in and out of alignment with the passages to control the fluid flow through the fluid control device. Rotation of the rotatable control element with respect to the fixed control element in a first direction of rotation gradually aligns the respective inlet openings with their corresponding flow passages and thus gradually opens different passages within the fixed control element, which effectively opens such passages for fluid flow thereby. Conversely, rotation of the rotatable control element with respect to the fixed control element in an opposite, second direction of rotation gradually moves respective inlet openings out of alignment with the corresponding passage, effectively blocking the passage and thereby preventing fluid flow. Accordingly, by selectively rotating the rotatable control member, a user can control the number of passages through which the fluid can flow. The rotary openings of the rotatable control element can be slightly smaller than the inlet ends of the passages of the fixed control element in order to prevent contaminants from getting caught in the interface.
    Referring now to FIG. 1, a flow control assembly 10 is integrated into a control or throttle valve 12 that includes a valve housing 14 having an inlet housing 16 and an outlet housing 18, which together define a main valve passage 20 that extends therethrough. The inlet housing 16 defines an inlet portion of the main valve passage 20 and the outlet housing 18 defines an outlet portion of the main valve passage 20. Within the main valve passage 20 there is a rotary fork 22 which is connected to the flow control assembly 10, the rotary fork 22 having a handle 24 which is connected to it is coupled, the purpose of which is described in more detail below.

    The flow control assembly 10 is positioned in the main valve passage 20 and includes a fixed control element 26 (ie a first control element) and a rotatable control element 28 (ie a second control element / turntable) which is rotatable with respect to the first control element 26 between several different positions wherein each position is associated with a different volume of fluid flow through the flow control assembly 10. The fixed control element 26 includes a plurality of passages and the rotatable control element 28 includes a plurality of openings, each opening being associated with a corresponding one of the plurality of passages, so that a given opening and the corresponding passage together define a flow control passage when the opening is aligned with the corresponding passage is (ie overlapped). It is contemplated that the fixed control element 26
    and the rotatable control element 28 in several different Implementations be executed can, how below in more detail is discussed. With reference on Figure 2 to 7 will be now more detailed
    Views of the flow control assembly 10 shown. As can be seen, the fixed control element 26 and the rotatable control element 28 are both arranged around a central axis 30. The fixed control element 26 has a plurality of nested rings or sleeves which are arranged around a central body, while the rotatable control element 28 has a turntable.
    4 and 5, the fixed control element 26 has, starting at the outer circumference of the fixed control element 26 and moving radially inwards, a first sleeve 32 which has an upper surface 34, a lower surface 36, a Includes outer surface 38 and an inner surface 40 that defines a first sleeve opening 42. Both the outer surface 38 and the inner surface 40 extend between the upper surface 34 and the lower surface 36 and define an outer diameter and an inner diameter, respectively.
    A second sleeve 44 is positioned concentrically within the first sleeve 32 and includes an upper surface 46, a lower surface 48, an outer surface 50, and an inner surface 52 that defines a second sleeve opening 54. Both the
    10/46 uescannz tJH / ül / £ ÜZÜ
    The outer surface 50 and the inner surface 52 extend between the upper surface 46 and the lower surface 48 and define an outer diameter and an inner diameter, respectively. The outer diameter of the second sleeve 44 is substantially equal to the inner diameter of the first sleeve 32, so that the second sleeve 55 can be received in the first sleeve opening 42, the second sleeve outer surface 50 being frictionally engaged with the first sleeve inner surface 40.
    The second sleeve 44 includes two grooves 56 formed therein, each groove 56 extending into the outer surface 50 and extending completely from the upper surface 46 to the lower surface 48. In the embodiment, each groove 56 is formed by a pair of opposed side walls and a bottom wall extending between the pair of side walls. In one embodiment, the pair of sidewalls are slightly chamfered with the distance between the sidewalls decreasing along the depth of the groove 56. In other words, as the distance from the outer surface 50 within the groove 56 increases, the distance between the side walls decreases. The grooves 56 are evenly spaced along the circumference of the second sleeve 44 by a 180 degree step.
    The grooves 56 formed in the second sleeve 44 each include eight turns along the length thereof, which means that each groove 56 is sized and structured to extend along at least two different axes. In particular, each groove 56 includes a first segment 58, a second segment 60, a third segment 62, a fourth segment 64, a fifth segment 65, a sixth segment 66, a seventh segment 68, an eighth segment 70 and a ninth segment 72 . The first, third, fifth, seventh and ninth segments 58, 62, 65, 68, 72 all extend in one direction, generally parallel to the central axis 30, while the second, fourth, sixth and eighth segments 60, 64, 66 , 70 extend in a circumferential direction that is generally perpendicular to the central axis 30. The various segments create the turns in each groove 56, with each pair of adjacent segments defining a respective turn. The tortuous configuration of each groove 56 results in a pressure drop in a fluid flowing through the grooves 56.
    A third sleeve 74 is concentric within the second

    Sleeve 44 positions and includes an upper surface 76, a lower surface 78, an outer surface 80, and an inner surface 82 that defines a third sleeve opening 84. Both the outer surface 80 and the inner surface 82 extend between the upper surface 76 and the lower surface 78 and define an outer diameter and an inner diameter, respectively. The outer diameter of the third sleeve 74 is substantially equal to the inner diameter of the second sleeve 44, so that the third sleeve 74 can be received in the second sleeve opening 54, the third sleeve outer surface 80 being frictionally engaged with the second sleeve inner surface 52.
    The third sleeve 74 includes two grooves 86 formed therein, each groove 86 extending into the outer surface 80 and extending completely from the upper surface 76 to the lower surface 78. The grooves 86 may have a tapered configuration, as described above with respect to the second sleeve grooves 56. The grooves 86 are evenly spaced along the circumference of the third sleeve 74 by a 180 degree step.
    The grooves 86 formed in the third sleeve 74 each include four turns along their length. In particular, each groove 86 includes a first segment 88, a second segment 90, a third segment 92, a fourth segment 94, and a fifth segment 96. The first, third, and fifth segments, 88, 92, 96 all extend in one direction, generally parallel to the central axis 30, while the second and fourth segments, 90, 94 extend in a circumferential direction, generally perpendicular to the central axis 30 is.
    A fourth sleeve 98 is positioned concentrically within the third sleeve 74 and includes an upper surface 100, a lower surface 102, an outer surface 104, and an inner surface 106 that defines a fourth sleeve opening 108. Both the outer surface 104 and the inner surface 106 extend between the upper surface 100 and the lower surface 102 and define an outer diameter and an inner diameter, respectively. The outer diameter of the fourth sleeve 98 is substantially equal to the inner diameter of the third sleeve 74, so that the fourth sleeve 98 can be received in the third sleeve opening 84, the outer surface of the fourth sleeve 104 being frictionally engaged with the inner surface 82 of the third sleeve 74 in

    Intervention stands.
    The fourth sleeve 98 includes four grooves 110 formed therein, each groove 110 extending into the outer surface 104 and extending completely from the upper surface 100 to the lower surface 102. The grooves 110 may each have a tapered configuration, as described above. The grooves 110 are evenly spaced along the circumference of the fourth sleeve 98 by ninety degree steps.
    The grooves 110 formed in the fourth sleeve 98 each include two turns along their length. In particular, each groove includes a first segment 112 that extends in a direction parallel to the central axis 30, a second segment 114 that extends in a circumferential direction, generally perpendicular to the first segment 112, and a third segment 116 that extends generally parallel to the first segment 112 and the central axis 30.
    The central body 118 is an elongated, generally cylindrical body having an upper surface 120, a lower surface 122 and a side surface 124 that extends between the upper surface 120 and the lower surface 122 and defines an outer diameter of the central body. The side surface 124 of the central body 118 is substantially equal to the inner diameter of the fourth sleeve 98, so that the central body 118 is received concentrically in the fourth sleeve opening 108, the side surface 124 of the central body 118 being frictionally engaged with the inner surface 106 of the fourth sleeve 98 in Intervention stands.
    Four grooves 126 are formed in the central body 118, with each groove 126 extending into the side surface 124 and extending completely from the top surface 120 to the bottom surface 122. The grooves 126 formed in the central body 118 are axial grooves, i. H. they are generally straight, extend along a single axis, and have no turns or bends along their length (i.e., from top surface 120 to bottom surface 122). The grooves 126 are evenly spaced along the circumference of the central body 118 by ninety degree steps.
    If the fixed control element 26 is assembled, the sleeves 32, 44, 74, 98 being nested concentrically around the central body 118, as shown in FIG. 6,

    Referring now to FIG. 7, an embodiment of the rotatable control member 28 is shown and includes a washer body 136 having a plurality of openings therein which are specifically sized and positioned to correspond to certain passageways formed in the fixed control member 26. In particular, the openings are spaced apart from the central axis 30 by certain radial distances with respect to the central axis 30, so that the radial distance between the openings corresponds to the radial distance between the passages which are formed in the fixed control element 26.
    Disk body 136 includes a pair of first stage openings 138, generally diametrically opposed, starting from the outer periphery of disk body 136 and working radially inward. Each first stage opening 138 extends along a path spaced from the central axis 30 by a first radial distance rl.

The third stage openings 142 correspond to the third stage passages 132 formed in the fixed control member 26. Each third stage opening 142 defines an area larger than that of the opening of the corresponding third stage passage 132.
    Moving radially inward from the third stage opening 142, the disc body 136 further includes four fourth stage openings 144 that are evenly spaced about the central axis 30. The fourth stage openings 144 correspond to the fourth stage passages 134 formed in the fixed control member 26.

    In addition to the first, second, third, and fourth stage openings 138, 140, 142, 144, the disk body 136 also includes a pair of engagement recesses 146, each engagement recess 146 being sized and positioned to receive a portion of the rotary fork 22 to facilitate the connection between the rotary fork 22 and the rotatable control element 28.
    The various positions of the rotatable control element 28 with respect to the fixed control element 26 will now be described with reference to FIGS. 8Ά to 8E. Figure 8A shows the rotatable control member 28 in a closed position with respect to the fixed control member 28. In the closed position, the first stage openings 138, second stage openings 140, third stage openings 142 and fourth stage openings 144 are not the same Aligned passages 128 of the first stage, passages 130 of the second stage, passages 132 of the third stage and passages 134 of the fourth stage. As such, the flow control assembly effectively forms a cone within the main valve passage 20 by preventing fluid from flowing through one of the first stage passages 128, second stage passages 130, third stage passages 132, and fourth stage passages 134 .
    In FIG. 8B, the rotatable control element 28 was rotated by a first rotation distance D1 with respect to the position shown in FIG. 8A in order to assume a first open position. In the first open position, the first stage openings 138 are at least partially aligned with the openings of the corresponding first stage passages 128, while the second stage openings 140, third stage openings 142, and fourth stage openings are out of alignment with the corresponding passages 130 of the second stage, passages 132 of the third stage, passages 134 of the fourth stage remain. Thus, when the rotatable control member 28 is in the first open position, fluid can flow through the first stage passages 128 while preventing fluid from passing through the second stage passages 130, third stage passages 132 and fourth stage passages 134 flows.

    In FIG. 8C, the rotatable control element 28 has been rotated by a second rotation distance D2 with respect to the position shown in FIG. 8A in order to assume a second open position. In the second open position, the first stage openings 138 are aligned with the openings of the corresponding first stage passages 128 due to the extended arc length of the first stage openings 138. When the rotatable control member 28 is also in the second position, the second stage openings 140 are at least partially aligned with the openings of the corresponding second stage passages 130. Third stage openings 142 and fourth stage openings 144 remain out of alignment with corresponding third stage passages 132 and fourth stage passages 134. Thus, when the rotatable control member 28 is in the second open position, fluid can flow through the first stage passages 128 and second stage passages 130 while preventing fluid from passing through the third stage passages 132 and fourth stage passages 134 flows.
    In FIG. 8D, the rotatable control element 28 has been rotated by a third rotation distance D3 with respect to the position shown in FIG. 8A in order to assume a third open position. In the third open position, the first stage openings 138 are aligned with the openings of the corresponding first stage passages 128, the second stage openings 140 are aligned with the openings of the corresponding second stage passages 130. In addition, third stage openings 142 are at least partially aligned with the openings of corresponding third stage passages 142. The fourth stage openings 144 remain out of alignment with the corresponding fourth stage passageways 134. Thus, when the rotatable control member 28 is in the third open position, fluid may flow through the first stage passages 128, the second stage passages 130, and the third stage passages 132 while preventing fluid from passing through the passages 134 of FIG fourth stage flows.
    In FIG. 8E, the rotatable control element 28 has been rotated by a fourth rotation distance D4 with respect to the position shown in FIG. 8A in order to assume a fourth open position. In

    Scanned 09/01/2020 of the fourth open position, the first stage openings 138 are aligned with the openings of the corresponding first stage passages 128, the second stage openings 140 are aligned with the openings of the corresponding second stage passages 130, and the openings Third stage 142 are aligned with the openings of the corresponding third stage passages 142. In addition, fourth stage openings 144 are at least partially aligned with corresponding fourth stage passages 134. Thus, when the rotatable control member 28 is in the fourth open position, fluid can flow through the first stage passages 128, the second stage passages 130, the third stage passages 132 and the fourth stage passages 134.
    In one embodiment, rotatable control member 28 may transition from the closed position to the fully open position (i.e., the fourth open position) by rotating less than ninety degrees and in some cases rotating less than eighty degrees. Thus, the fluid flow through the flow control assembly 10 can be controlled by relatively small degrees of twist.
    The flow control assembly 10 is specially designed to allow opening of the first stage passages 128, second stage passages 130, third stage passages 132 and fourth stage passages 134 in a radially inward direction. Specifically, first stage passages 128 open first and are the greatest radial distance from central axis 30. Second stage passages 130 open second, followed by third stage passages 132 and then fourth stage passages 134 in FIG a progressively radially inward direction. In contrast, the passageways are closed in a radially outward direction, with fourth stage passageways 134 closing first, followed by third stage passages 132, second stage passages 130, and finally passages 128 of the first Step.
    The movement of the rotatable control element 28, 28 with respect to the fixed control element 26 can be controlled manually via the handle 24, which can move within a slot formed within the inlet housing 16. The

    Scanned 09/01/2020
    Handle 24 is connected to rotatable control element 28 via rotary fork 22, and thus, by rotating handle 24, rotatable control element 28 is also rotated. It is also contemplated that the rotatable control element may be actuated by a rotary actuator and linkage assembly.
    According to one embodiment, the fixed control element 26 and the rotatable control element 28 can be made of
    Tungsten carbide or other metallic materials known in the prior art. It is also contemplated that control elements 26, 28 may be formed by a laser sintering process or by using green state manufacturing processes. An example of a laser sintering process and a green state manufacturing process is described in US Patent No. 8,826,938 entitled "Direct Metal Laser Sintered Flow Control Element", the contents of which are expressly incorporated herein. If necessary, 3D printing can also be used to facilitate the production of one or both control elements 26, 28. In addition, those of ordinary skill in the art will recognize that the foregoing description of control elements 26, 28 and their nature of flow-regulating interaction are intended to reflect an exemplary optimal implementation, and that certain variations should also be included in the spirit and scope of the present disclosure. By way of example, certain variations contemplated include, but are not limited to: 1) Variations in the size (e.g., length and / or diameter) and / or number of concentrically positioned sleeves included in the fixed control element 26 ; 2) variations in geometry (e.g. size, shape and / or depth), arrangement and / or number of passages 128, 130, 132, 134 of the first, second, third and / or fourth stage; 3) Variations in the size (e.g. length and / or diameter) of the rotatable control element 28 and 4) Variations in the geometry (e.g. size, shape and / or depth), arrangement and / or number of openings 138 , 140, 142, 144 of the first, second, third and fourth stages. As will be seen, the implementation of any of these variations in any combination can be determined by prescribed criteria for throttle valve performance

    With reference to FIG. 9, a further control or throttle valve 200 is now shown, which includes a second exemplary embodiment of the flow control assembly 210. Figure 10 is a top perspective view of the flow control assembly 210 disposed about a central axis 212 and generally including a rotatable control element 214 (e.g., a turntable) and a fixed control element 216 consisting of a plurality of stacked disks. Assembled, the fixed control element 216 and the rotatable control element 214 form a disc stack, which has discs of similar circumference or diameter, and which can be accommodated in the main passage 20 of the control valve 200. The fixed control element 216 and the rotatable control element 214 together define a plurality of control passages that are selectively opened and closed by relative rotation of the rotatable control element 214 with respect to the fixed control element 216.
    The rotatable control element 214 is arranged around the central axis 212 and includes a disk body 218 with a plurality of openings formed therein. In particular, the disk body 218 includes a pair of first stage openings 220 generally opposed to each other, starting from the central axis 212 and moving radially outward to the outer periphery. Each first stage opening 220 extends along a path spaced from the central axis 212 by a first radial distance RI. Each opening 220 of the first stage also extends around the central axis by a first angular distance Φ1. The first stage openings 220 correspond to a first stage passage formed in the fixed control element 216. Each first stage opening 220 defines an area larger than that of the opening of the corresponding first stage passage, the meaning of which will be described in more detail below.
    Moving radially outward from the first stage opening 220, the disk body 218 further includes four second stage openings 222 that are evenly spaced about the central axis 212. Each second stage opening 222 extends along a path that is spaced apart from the central axis 212 by a second radial distance R2 that is larger

Each second stage opening 222 also extends about the central axis 212 by a second angular distance Φ2 that is less than the first angular distance Φ1. The second stage openings 222 correspond to second stage passageways formed in the fixed control element 216. Each second stage opening 222 defines an area larger than that of the opening of the corresponding second stage passage.
    Moving radially outward from the second stage opening 222, the disc body 218 further includes four third stage openings 224 that are evenly spaced about the central axis 212. The third stage openings 224 correspond to third stage passageways formed in the fixed control element 216. Each third stage opening 224 extends along a path that is spaced from the central axis 212 by a third radial distance R3 that is greater than the second radial distance R2. Each third stage opening 224 defines an area approximately equal to the size of the opening of each third stage passage.

    Figures 11 and 12 are exploded views of the flow control assembly 210, and when viewed from the perspectives shown therein, the rotatable control element 214 is shown on the right side and the washers, the fixed control element 216 (e.g., the fixed washers) are located to the left of the rotatable control element 214. The rotatable control element 214 is located upstream of the fixed disks, so that fluid first enters the rotatable control element 214 before it flows through the fixed disks.
    The fixed control element 216 includes four discs, including a first disc 226 adjacent to the rotatable control element 214, followed by a second disc 228, a third disc 230 and a fourth disc 232.

A pair of first stage openings 238 are formed in the first disc 226 and extend completely from the first side 234 to the second side 236. The first stage openings pair 238 are each spaced a first radial distance from the central axis 212 and aligned along a common diameter. Four second stage openings 240 are also formed in the first disc 226 and extend completely from the first side 234 to the second side 236. The second stage openings 240 are each spaced apart from the central axis 212 by a second radial distance which is larger than the first radial distance is.

The recesses do not extend completely from the second side 236 to the first side 234; rather, they end just before the first side 234 to define an interface between the first and second sides 234, 236. In particular, the first disc 226 includes a pair of first stage recesses 244 and four second stage recesses 246. Each first stage recess 244 forms part of a respective first stage passage, while each second stage recess 246 forms part of a respective second stage passage, as will be described in more detail below.

    As noted above, the first, second, third, and fourth disks 226, 228, 230, 232 together define the first stage pass, the second stage pass, and the third step pass. Referring now to FIG. 13, there is shown a cross-sectional perspective view of the fixed control element 214, with certain openings and recesses thereof being shown in dashed lines to illustrate an exemplary passage of the passages of the first stage. As fluid flows through the first stage passage, the fluid flows through the first stage opening 238 in the first disc 226, then through the primary first stage opening 252 in the second disc 228, then through the first stage recess 266 in the third disc 230, then through the secondary opening 254 of the first stage and recess 244 of the first stage in the second and first discs 228, 226, respectively, and then through aligned openings 268, 284 of the first stage in the third and fourth discs 230, 232.

In this regard, the passage of the second stage extends along three different axes and includes seven segments and six turns.
    With reference to FIG. 15, an exemplary passage of the third stage is now shown. As fluid flows through the third stage passage, the fluid flows through the third stage opening 242 in the first disc 226, through the third stage opening 260 in the second disc 228, through the third stage opening 276, and the recess 278 the third stage in the third disc 230, through the recess 288 of the third stage in the fourth disc 232 and through the opening 290 of the third stage in the fourth disc 232. In this regard, the passage of the third stage extends along three different axes and includes five segments and six turns.
    16Ά to 16D, the various positions of the rotatable control element 214 with respect to the fixed control element 216 will be described. Figure 16A shows the rotatable control member 214 in a closed position with respect to the fixed control member 216. In the closed position, the openings 220 of the first stage, openings 222 of the second stage and openings 224 of the third stage are not with the corresponding openings of the passages of the first stage , the passages of the second stage, the passages of the third stage. As such, the flow control assembly 210 effectively forms a cone within the main valve passage 20 by preventing fluid from flowing through one of the first stage passages, second stage passages, and third stage passages.
    In FIG. 16B, the rotatable regulating element 214 was rotated by a first rotation distance d1 with respect to the position shown in FIG. 16A in order to assume a first open position. In the first open position, the openings 220 of the first stage of the rotatable control element 214 are at least partially with
    26/46
    Scanned 09/01 / Z0Z0 corresponding openings of openings 238 of the first stage aligned on the first disc 226, while openings 222 of the second stage and openings 224 of the third stage out of alignment with their corresponding openings 240 of the second stage and openings 240 of the third Stay on the first disc 226. Thus, when the rotatable control member 214 is in the first open position, fluid can flow through the first stage passages while preventing fluid from flowing through the second stage passages and third stage passages.
    In FIG. 16C, the rotatable control element 214 has been rotated by a second rotation distance d2 with respect to the position shown in FIG. 16A in order to assume a second open position. In the second open position, the first stage openings 220 of the rotatable control member 214 are aligned with the first stage openings 238 on the first disc 226 due to the extended arc length of the first stage openings 220. In addition, when the rotatable control member 214 is in the second position, the second stage openings 222 of the rotatable control member 214 are at least partially aligned with the second stage openings 240 of the first disc 226. Third stage openings 224 of rotatable control member 214 remain out of alignment with corresponding third stage openings 242 of first disc 226. Thus, when rotatable control member 214 is in the second open position, fluid can pass through the first stage passages and passages of the second stage while preventing fluid from flowing through the passages of the third stage.
    In FIG. 16D, the rotatable control element 214 was rotated by a third rotation distance d3 with respect to the position shown in FIG. 16A in order to assume a third open position. In the third open position, the first stage openings 220 of the rotatable control member 214 are aligned with the first stage openings 238 on the first disc 226 and the second stage openings 222 of the rotatable control member 214 are with the second stage openings 240 of the first Disk 226 aligned. In addition, third stage openings 224 of rotatable control member 214 are at least partially associated with corresponding third stage openings 242 of the first
    27/46 scanned tjy / 01/2020
    Disk 226 aligned. Thus, when the rotatable control member 214 is in the third open position, fluid can flow through the first stage passages, the second stage passages and the third stage passages.
    In one embodiment, rotatable control member 214 may transition from the closed position to the fully open position (i.e., the third open position) by rotating less than ninety degrees and in some cases rotating less than eighty degrees. Thus, the fluid flow through the flow control assembly 210 can be controlled by relatively small degrees of twist.
    The flow control assembly 210 is specially designed to allow opening of the first stage, second stage and third stage passages in a radially outward direction. In particular, the passages of the first stage open first and have the smallest radial distance from the central axis 212. The passages of the second stage open as the second, followed by the passages of the third stage in a progressively radially outward direction. In contrast, the passageways are closed in a radially inward direction, with the third stage passageways closing first, followed by the second stage passageways and finally the first stage passageways.
    According to one embodiment, the fixed control element 216 and the rotatable control element 214 can be formed from tungsten carbide or other metallic materials known in the art. It is also contemplated that control elements 214, 216 may be formed by a laser sintering process or by using a green state manufacturing process.
