Description

background

[0001] A rotary cone valve is a type of directional control valve used in a fluid supply system to control fluid flow and distribution. For example, rotary cone valves can be used to control the flow of coolant through a vehicle cooling system. The rotary cone valve may consist of a valve body, which defines multiple ports, and a valve cone located within the valve body. The valve cone is shaped to direct the flow to predetermined ports for certain rotational orientations of the cone within the valve body and is rotated relative to the valve body to control the flow through the valve.

[0002] For example, US 2019 / 0 162 320 A1 describes a flow control valve comprising a housing forming a number of internal passages and an internal cavity in fluid communication with each of the internal passages, and a flow direction block arranged in the internal cavity, the flow direction block having an outer surface surrounded by an inner surface of the internal cavity. DE 10 2019 133 340 A1 describes a valve used to regulate the flow of a cooling fluid used for temperature control of the engine or other components of a motor vehicle. DE 42 10 312 A1 describes a device for selectively pressurizing one or more molds for plastics processing with a liquid or a pressurized gas. Brief description

[0003] Complex fluid supply systems may require a rotary cone valve capable of controlling fluid flow between three, four, five, or more individual ports on the valve body. Depending on the system requirements, it may be desirable to close different flow paths simultaneously. For example, with a five-port rotary cone valve, it may be desirable to close up to three of the five flow paths for a given rotational orientation of the valve cone relative to the valve body. This requires that a large angular portion of the valve cone has no fluid passage openings. If all valve ports are located at the same height along a vertical dimension of the valve body, the area available for closed ports is limited.In the rotary cone valve disclosed here, the flow paths of the valve cone are split across two heights, thus providing a larger area on the cone without a fluid passage opening that intersects a valve body port. However, a multi-height valve cone can be difficult to manufacture, requiring a complex mold and / or forming process. One solution involves the interface between the valve body and the valve cone having a conical shape, enabling the formation of a valve seal (also known as a valve seat) in a simple two-piece mold. However, the conical shape then complicates the formation of the valve cone in a simple two-piece mold without creating areas of significant wall thickness, a configuration associated with poor dimensional control of the part.To address this problem, the valve cone is formed in sections, allowing core removal (e.g., the removal of material) of the area inside the conical shape defined by the valve cone and outside the passages.

[0004] In some fluid supply systems, such as those with thermal applications, it may be desirable to close two or three of the ports in a given valve cone rotation position. For example, a multi-port rotary cone valve may be used in an electric vehicle cooling system to control the flow of coolant fluid between a radiator, an electric drive motor, a battery, the vehicle electronics, and one or more bypass lines. The rotary cone valve may comprise a valve body having ports at two or more heights along a height dimension of the valve body. The rotary cone valve may further comprise a valve cone assembly located within the valve body and rotatable about the valve body around an axis of rotation parallel to the height direction of the valve body. The valve cone assembly may consist of two interlocking parts (e.g.,The valve cone assembly consists of a first and a second cone section, which work together to control the fluid flow through the valve body. The valve cone assembly can have more than two openings for diverting fluid to the different levels. Adding levels and corresponding cone openings allows for valve configurations corresponding to certain rotational positions of the valve cone relative to the valve body, where fluid passages extend between levels, are restricted to a single level, or where no ports of the valve body are open. This can be compared to some conventional rotary cone valves that only allow one port to be closed at a time. The valve cone assembly provides some passages that have access to ports at multiple levels and others that have access only at one level.The two-part valve cone assembly simplifies the forming of a valve cone that can accommodate the additional port heights. The valve body and cone assembly can be tapered along the axis of rotation to simplify manufacturing and improve sealing.

[0024] With reference to Fig. 1-3 comprises a fluid supply system 1 and a multi-height, multi-port rotary cone valve 18 capable of controlling the fluid flow driven by a pump 8 between three, four, five, or more individual fluid lines 10, 11, 12, 13, 14 in the system 1. The rotary cone valve 18 can, for example, be used to control the distribution and flow of coolant in a cooling system 1 of an electric vehicle. In this example, the rotary cone valve 18 can control the flow of coolant fluid between the rotary cone valve 18 and a radiator 2, which is part of a vehicle passenger compartment heating and cooling system 7, with coolant from the radiator 2 also cooling a battery 3 and a battery management system 4. Furthermore, the rotary cone valve 18 can control the fluid flow to heat exchangers 5, 6, which support the temperature control of other vehicle devices and systems, such as…an electric drive motor, the vehicle electronics and / or electronic control units and / or the oil supply. The rotary cone valve 18 comprises a valve body 20 and a valve cone assembly 50, which is arranged in the valve body 20 and rotates about an axis of rotation 52 with respect to it. Furthermore, the rotary cone valve 18 has a single elastomeric valve seal 110, which provides a fluid-tight seal between the valve body 20 and the valve cone assembly 50. The valve body 20 comprises several valve ports 33, 34, 35, 36, 37, the number of ports being determined by the specific application. At least one valve port 33 is positioned at a different height along a height dimension of the valve body 20 than the other valve ports 34, 35, 36, 37, the height dimension being measured in a direction parallel to the axis of rotation 52.The rotational orientation of the valve cone assembly 50 relative to the valve body 20 is determined by an actuator (not shown). The rotational orientation of the valve cone assembly 50 relative to the valve body 20 determines one or more fluid flow paths through corresponding valve ports 33, 34, 35, 36, 37. The valve cone assembly 50 can be an arrangement of two interlocking parts 60, 80 which together control the fluid flow through the valve body 20. The valve cone assembly 50 has several openings, which are associated with passages 72, 92, 96 and which, depending on the rotational orientation of the valve cone assembly 50 relative to the valve body 20, divert fluid to specific valve ports 33, 34, 35, 36, 37, thereby controlling the distribution of coolant fluid in the cooling system 1. Details of the rotary cone valve 18, including the valve body 20, the valve cone assembly 50 and the seal 110, will now be described.

[0025] With reference to Fig. 4 and Fig. The valve body 20 comprises a body base 26 and a body side wall 21. The body base 26 has a circular profile when viewed in a direction parallel to the axis of rotation 52. The body side wall 21 is connected at one end (referred to here as the "base end") 22 to a circumferential edge of the body base 26, and the body side wall 21 surrounds the body base 26. The body side wall 21 and the body base 26 together form a generally cup-shaped structure that defines a valve body chamber 30 therein. An open end 23 of the body side wall 21 (e.g., the end of the body side wall 21 that is spaced away from the body base 26) has a diameter larger than the diameter of the base end 22, causing the body side wall 21 to open at an obtuse angle θ1 ( Fig. 5) projects towards the body base 26. In the illustrated embodiment, the angle θ1 lies in a range of 95 to 150 degrees, for example 97 degrees.

[0026] In the illustrated embodiment, the valve body 20 comprises five valve ports 33, 34, 35, 36, 37, but is not limited to this number of ports. In particular, the valve body 20 comprises a first valve port 33, a second valve port 34, a third valve port 35, a fourth valve port 36, and a fifth valve port 37. Each of the valve ports 33, 34, 35, 36, 37 projects outward from the body side wall 21 along a radius of the axis of rotation 52 and communicates with the valve body chamber 30. In the illustrated embodiment, the valve ports 33, 34, 35, 36, 37 are cylindrical tubes, and each valve port 33, 34, 35, 36, 37 forms a circular opening at the interface with the body side wall 21.

[0027] In the illustrated embodiment, the valve ports 33, 34, 35, 36, 37 are cylindrical tubes, and each valve port 33, 34, 35, 36, 37 forms a circular opening at the interface with the body side wall 21. Although the valve ports 33, 34, 35, 36, 37 have the same length, cross-sectional shape, and dimensions as shown, they are not limited to this configuration. Furthermore, the valve ports 33, 34, 35, 36, 37 are not limited to the coplanar and radially oriented configuration shown. For example, in other embodiments, certain valve ports 33, 34, 35, 36, 37 may not be coplanar with the other valve ports and / or may project from the base instead of the side wall.The valve ports 33, 34, 35, 36, 37 can project in a direction parallel to the axis of rotation 16, in a direction perpendicular to the axis of rotation 16, or at any angle between perpendicular and parallel to the axis of rotation 16. The valve ports 33, 34, 35, 36, 37 cannot project radially; it is not necessary for an axis of a given valve port to intersect the axis of rotation 16. In many applications, the configuration of the valve ports 33, 34, 35, 36, 37 is determined by packaging requirements.

[0028] The valve ports 33, 34, 35, 36, 37 are provided at spaced-apart locations around the circumference of the body side wall 21. In the illustrated embodiment, the first and fourth valve ports 33, 36 are arranged on opposite sides of the valve body 20, extend parallel to a common diameter of the valve body 20, and are located at different heights along a height dimension of the valve body 20. In particular, the first valve port 33 is closer to the open end 23 of the valve body than the fourth valve port 36 when the valve body 20 is viewed in a direction perpendicular to the axis of rotation 52. The second and fifth valve ports 34, 37 are arranged on opposite sides of the valve body 20, are coaxial with a common diameter of the valve body, and share a height with the fourth valve port 36.The third valve port 35 shares a height with the second, fourth, and fifth valve ports 34, 36, 37 and is located between the second and fourth valve ports 34, 36. Thus, the first valve port 33 lies in a first plane P1, which is perpendicular to the axis of rotation 52, and the second, third, fourth, and fifth valve ports 34, 35, 36, 37 lie in a second plane P2, which is perpendicular to the axis of rotation 52 and spaced apart from the first plane. In the illustrated embodiment, plane P1 lies between plane P2 and the open end 23 of the valve body 20, but is not limited to this configuration.

[0029] The inner surface of the body side wall 21 is provided with grooves 32 extending between the base end 22 and the open end 23. The grooves 32 have the same cross-sectional shape as the ribs of the seal 110 and are dimensioned to receive the ribs of the seal 110 in an interference fit configuration, as discussed in more detail below. The number of grooves 32 provided corresponds to the number of ribs of the seal 110. In the illustrated embodiment, the valve body 20 comprises six grooves 32. At least one groove 32 is arranged between the ports of each adjacent pair of valve ports 33, 34, 35, 36, 37. For example, the first and second ports 33, 34, viewed in a direction parallel to the axis of rotation, form a pair of adjacent valve ports, and a groove 32 is arranged between the first and second ports 33, 34.Similarly, a groove 32 is provided between the second and third valve ports 34, 35, between the third and fourth valve ports 35, 36, between the fourth and fifth valve ports 36, 37, and between the fifth and first valve ports 37, 33. The spacing of the valve body grooves 32 around the inner circumference of the valve body 20 depends on the spacing of the valve body ports 33, 34, 35, 36, 37 and is therefore possibly not uniform.

[0030] The body side wall 21 has a height dimension that corresponds to the distance between the open end 23 of the side wall and the base end 22 of the side wall in a direction parallel to the axis of rotation. In the illustrated embodiment, the height dimension of the valve body is the same as, or slightly less than, the diameter of the base end of the side wall.

[0031] In some embodiments, a cover (not shown) is provided that closes an open end 23 of the valve body 20, whereas in other embodiments the open end 23 of the valve body 20 may be closed by a housing (not shown) of the actuator or another additional structure. A second seal (not shown) may be arranged between the open end 23 of the valve body and the cover or housing.

[0032] With reference to Fig. 6 and Fig. In section 7, the valve cone assembly 50 is arranged in the valve body chamber 30 and is rotatable in the chamber 30 about the axis of rotation 52. The valve cone assembly 50 is an arrangement of a first cone section 60 and a second cone section 80, which are stacked together along the axis of rotation 52. The mating surfaces of the first and second cone sections 60, 80 are interlocking, causing the first and second cone sections 60, 80 to rotate together and interact to control the fluid flow through the valve body 20.

[0033] With reference to Fig. In sections 8-12, the first conical section 60 comprises a first base 66 and a first side wall 61. The first base 66 is parallel to the body base 26 and has a circular profile when viewed in a direction parallel to the axis of rotation 52. The first base 66 has an outer surface 67 facing the body base 26 and an opposite inner surface 68 facing away from the body base 26. The first side wall 61 is connected at one end (here referred to as the "base end") 62 to a circumferential edge of the first base 66. The first side wall 61 surrounds the first base 66 and is centered on the axis of rotation 52. The first side wall 61 and the first base 66 together form a generally cup-shaped structure. An open end 63 of the first side wall 61 (e.g.,the end of the first side wall 61, which is spaced from the first base 66) has a diameter that is larger than the diameter of the base end 62, whereby the first side wall 61 is at an oblique angle θ2 (. Fig. 5) projects to the first base 66. In the illustrated embodiment, the angle θ2 lies in a range of 95 to 150 degrees, for example at 97 degrees.

[0034] The first side wall 61 includes an alpha opening 70 and a beta opening 71, which are spaced apart along a circumference of the first side wall 61. With respect to a reference diameter D1 ( Fig. 12) of the valve cone arrangement 50, the alpha and beta openings 70, 71 are on the same side of the reference diameter D1 when the valve cone arrangement 50 is viewed in a direction parallel to the axis of rotation 52.

[0035] The first conical section 60 includes a projection 73 that extends from the outer surface 67 of the base and intersects the first side wall 61 at a point corresponding to the beta opening 71. The projection 73 is hollow and has the shape of a right quadrilateral prism. The projection 73 extends along a radius of the first base 66 and has a minimum height dimension at a point between a center point of the first base 66 and a circumferential edge of the first base 66. The projection has a maximum height at the first side wall 61. The projection 73, together with the first side wall 61, defines the beta opening 71, the beta opening 71 having a height dimension h1 that is greater than a height dimension h2 of the first side wall 61.

[0036] The first cone section 60 comprises a first fluid passage 72, which extends along and projects from the inner surface 68 of the base. The first fluid passage 72 extends between the alpha opening 70 and the beta opening 71. The first fluid passage 72 comprises a first linear section 74, which extends along a radius of the first base 66 between the alpha opening 70 and the center of the first base 66, and a second linear section 75, which extends along a radius of the first base 66 between the beta opening 71 and the center of the first base 66. An interior angle θ3 ( Fig. 9) The angle between the first linear section 74 and the second linear section 75 is less than 180 degrees. In the illustrated embodiment, the internal angle θ3 is approximately 135 degrees.

[0037] The first conical section 60 comprises a hollow cylindrical stub 76 projecting from an outer surface of the first fluid passage 72. The stub 76 is coaxial with the longitudinal axis and has surface features, such as flats, axial splines, or gear teeth, that allow engagement with an output shaft of the actuator, whereby the first conical section 60 can be driven by the actuator to rotate about the axis of rotation 52. In the illustrated embodiment, the surface features are external. In other embodiments, the surface features may be internal. In the illustrated embodiment, the stub 76 has a low profile in that the sum of the height dimensions of the stub 76 and the first fluid passage 72 is less than or equal to the height dimension of the first side wall 61.In further embodiments, the stump 76 can have a high profile and protrude from the first conical section 60, as required by the specific application.

[0038] With reference to Fig. In figures 13-17, the second conical section 80 comprises a second base 86 and a second side wall 81. The second base 86 has a circular profile when viewed in a direction parallel to the axis of rotation 52. The second base 86 has an outer surface 87 facing the body base 26 and an opposite inner surface 88 facing away from the body base 26 and towards the first base 66. The second side wall 81 is connected at one end (referred to here as the "base end") 82 to a circumferential edge of the second base 86. The second side wall 81 surrounds the second base 86 and is centered on the axis of rotation 52. The second side wall 81 and the second base 86 together form a generally cup-shaped structure. An open end 83 of the second side wall 81 (e.g.,the end of the second side wall 81, which is spaced from the second base 86) has a diameter that is larger than the diameter of the base end 62, whereby the second side wall 81 is at an oblique angle θ4 (. Fig. 5) projects to the second base 86. In the illustrated embodiment, the angle θ4 lies in a range of 95 to 150 degrees, for example at 97 degrees.

[0039] The second side wall 81 comprises a delta opening 90, a gamma opening 91, and a zeta opening 95, which are spaced apart from each other along a circumference of the second side wall 81. With respect to the reference diameter D1 ( Fig. 13) In the valve cone arrangement 50, the delta and gamma openings 90, 91 are located on the same side of the reference diameter D1 when the valve cone arrangement 50 is viewed in a direction parallel to the axis of rotation 52. Furthermore, the delta and gamma openings 90, 91 are located on the opposite side of the reference diameter D1 with respect to the zeta, alpha and beta openings 95, 70, 71.

[0040] The second cone section 80 comprises a second fluid passage 92, which extends along and projects from the inner surface 88 of the base. The second fluid passage 92 extends between the delta opening 90 and the gamma opening 91. The second fluid passage 92 comprises a first linear section 93, which extends along a radius of the second base 86 between the delta opening 90 and a midpoint of the second base 86, and a second linear section 94, which extends along a radius of the second base 86 between the gamma opening 91 and the midpoint of the second base 86. An interior angle θ5 ( Fig. 15) The angle between the first linear section 93 and the second linear section 94 is less than or equal to 180 degrees. In the illustrated embodiment, the internal angle θ5 of the second fluid passage 92 is less than the internal angle θ3 of the first fluid passage 72. For example, the internal angle θ5 is approximately 112 degrees.

[0041] The Zeta orifice 95 is a blind orifice configured to connect adjacent valve ports in certain rotational orientations of the valve cone assembly 50 with respect to the valve body 20. For this purpose, the Zeta orifice 95 has a dimension along a circumference of the second side wall 81 that is at least twice the dimension along a circumference of the second side wall 81 of the Delta and Gamma orifices 90, 91, whereby the Zeta orifice 95 generally has a sector shape when considering the cross-section of the second cone section 80. Fig. 13). The zeta opening 95 serves as a third fluid passage 96, which extends along the inner surface 88 of the base and projects from it.

[0042] The second cone section 80 includes a recess 98 formed in the open end 83 of the second side wall. The recess 98 is located between the zeta opening 95 and the delta opening 90. The opening of the recess 98 faces away from the second base 86 and is shaped and dimensioned to receive the projection 73 with a play fit. The interaction between the projection 73 and the recess 98 ensures that the first and second cone sections 60, 80 rotate in unison about the axis of rotation 52.

[0043] With renewed reference to Fig. In the valve cone assembly 50, the first cone section 60 is axially aligned with the second cone section 80 such that the outer surface 67 of the base of the first cone section 60 rests against the open end 83 of the second side wall, and the projection 73 is located in and engages with the recess 98. In this configuration, the projection 73 acts as a wedge that engages with the recess 98 in such a way that the first cone section 60 and the second cone section 80 are fixed to one another and can be rotated together as a single unit about the axis of rotation 52. Furthermore, the beta opening 71 is partially accommodated in the recess 98, allowing the first fluid passage 72 to provide a flow connection between the heights of the valve body 20 in certain rotational orientations of the valve cone assembly 50 relative to the valve body 20.In the valve cone arrangement 50, the second cone section 80 is arranged between the first cone section 60 and the body base 26. The second base 86 is spaced from the first base 66 in a direction parallel to the axis of rotation 52, with the second side wall 82 and the second and third fluid passages 92, 96 arranged between the first base 66 and the second base 86. Furthermore, the first and second side walls 61, 81 are aligned.

[0044] With reference to Fig. Figures 18-19 show that the seal 110 is a cage-like structure comprising a first ring 111, a second ring 112 parallel to and spaced apart from the first ring 111, and linear ribs 113 extending between the first ring 111 and the second ring 112. The first ring 111 has a first diameter d1 corresponding to the inner diameter of the valve body 20 at the open end 23 of the side wall. The second ring 112 has a second diameter d2 corresponding to the inner diameter of the valve body 20 at the base end 22 of the side wall. Since the valve body has a conical profile with a larger diameter at the open end 23 of the side wall than at the base end 22 of the side wall, the second diameter d2 is smaller than the first diameter d1. The seal 110 comprises an inner surface 114 which points to the axis of rotation 52 and the valve cone arrangement 50.The first and second cone sections 60, 80 of the valve cone arrangement 50 are in contact with the inner surface 114 of the seal 110.

[0045] The ribs 113 are spaced apart around the circumference of the first and second rings 111, 112. At least one rib 113 is arranged between each valve port. In the illustrated embodiment, where the valve body 20 comprises five valve ports 33, 34, 35, 36, 37, the seal comprises six ribs 113. In other embodiments, however, providing two ribs 113 between a pair of adjacent ports can provide a blocked area or a sealed port. The specific spacing of the ribs 113 along a circumference of the first and second rings 111, 112 depends on the spacing of the grooves 32 of the valve body, which in turn depends on the spacing of the valve body ports 33, 34, 35, 36, 37 along a circumference of the body side wall 21 of the valve body.Furthermore, the relationship of the ribs 113 and the grooves 32 of the valve body to the valve ports 33, 34, 35, 36, 37 defines the time of opening of the valve ports 33, 34, 35, 36, 37.

[0046] Both the first and second rings 111, 112 and the ribs 113 have a rectangular cross-sectional shape. Furthermore, the inner surface 114 of each rib 113 includes a channel 115 extending between the first ring 111 and the second ring 112. The channel 115 can be shaped and dimensioned to prevent the inclusion of impurities or foreign bodies carried in the fluid. The channel 115 can also reduce the contact area between each rib 113 and the valve cone assembly 50. In the illustrated embodiment, the channel 115 can have a V-shaped profile. In this case, the inner surface 114 of each rib 113 includes a pair of parallel webs 116, with one web 116 arranged on each side of the channel 115. The webs 116 each provide a linear narrow sealing contact surface between the seal 110 and an outer surface of the valve cone assembly 50.In some embodiments, the webs 116, which delimit the channel 115, can serve to prevent the inclusion of contaminants and / or other foreign bodies in the seal / cone interface, thereby reducing abrasive wear.

[0047] The outer surface (e.g., the surface facing the valve body) 118 of each rib 113 is received in a corresponding axially extending groove 32 of the valve body 20. The shape or cross-sectional profile of the outer surface 118 corresponds to the shape of the groove 32. In the illustrated embodiment, the outer surface 118 has a rectangular shape, so that it corresponds to the rectangular shape of the groove 32.

[0048] The seal 110 is made of an elastic material that is compatible with the fluid flowing through the rotary cone valve 18 and meets the requirements regarding operating temperature and resistance. For example, for a fluid valve used to control fluid in a vehicle coolant system, the seal 110 is made of an elastomer compatible with the automotive coolant. In some embodiments, the seal 110 is formed as a single unit in a molding process. By forming the seal 110 as a single unit, the seal 110 is produced without seams (e.g., lines along which two pieces of the seal material are joined) or other joints, thereby improving the reliability and resistance of the seal 110 compared to some other manufacturing processes.

[0049] In some embodiments, the surfaces 114 of the seal 110 facing the valve cone assembly can include a friction-reducing coating, allowing these surfaces to have a lower coefficient of friction than the rest of the seal 110. In some embodiments, the entire seal 110 is coated with a friction-reducing coating compared to the elastomer used to form the seal 110. In a non-limiting example, the seal 110 is formed from an elastomer, and the coating is formed from polytetrafluoroethylene (PTFE). By providing the seal 110 with a friction-reducing coating, the torque required to actuate the rotary cone valve 18 is reduced. In still other embodiments, the entire seal 110 is formed from a friction-reducing elastomer.

[0050] In use, the seal 110 is arranged in the valve body 20, with the first ring 111 adjacent to the open end 23 of the body side wall, the second ring 112 adjacent to the base end 22 of the body side wall, and the ribs 113 arranged in the grooves 32. The grooves 32 hold the seal 110 in a fixed configuration with respect to the valve body 20 when the valve cone assembly 50 rotates about the axis of rotation 52. The valve cone assembly 50 is arranged in the valve body chamber 30, with the seal 110 positioned between the valve cone assembly 50 and the body side wall 21. In this configuration, the first ring 111 of the seal surrounds the open end 63 of the first cone section and provides a fluid-tight annular seal between the first cone section 60 and the valve body 20.Furthermore, the second ring 112 of the seal surrounds the second conical section 80 of the second base 86 and provides a fluid-tight annular seal between the second conical section and the valve body 20. Each valve port 33, 34, 35, 36, 37 is also surrounded by a section of the seal 110 that includes an adjacent pair of ribs 113, and sections of the first and second rings 111, 112 that extend between the adjacent pair of ribs 113, thus creating a fluid-tight seal that separates each valve port from the other valve ports.

[0051] The rotary cone valve 18 comprises the valve body 20, which has five valve ports 33, 34, 35, 36, 37. The first valve port 33 is arranged at a first height L1 (e.g., at a first axial position), and the remaining valve ports 34, 35, 36, 37 are arranged at a second height L2 (e.g., at a second axial position). Furthermore, the valve cone assembly 50 is arranged in the valve body 20 such that it is sealed with respect to the valve body 20 by the seal 110. The valve cone assembly 50, which comprises the first and second cone sections 60, 80, which interlock, is rotatable about the axis of rotation 52 to control the fluid flow through the valve body 20. For example, in a rotational position of the valve cone assembly 50 with respect to the valve body 20 ( Fig. 20A, Fig. 20B) the first fluid passage 72 between the first and second heights L1, L2, thereby allowing fluid flow between the first valve port 33 and the fifth valve port 37. In this position, the second fluid passage 92 allows fluid flow between the third and fourth valve ports 35, 36, while the third fluid passage 96 is not used because it is not aligned with the multiple valve ports. In a further rotational position of the valve cone assembly 50 with respect to the valve body 20 ( Fig. 21A, Fig. 21B) the third fluid passage 96 is aligned with both the third and fourth valve ports 35, 36 and allows fluid flow between them. In this position, the first fluid passage 72 and the second fluid passage 92 are not used, as they do not extend between valve ports. In a further rotational position of the valve cone assembly 50 with respect to the valve body 20 ( Fig. 22A, Fig. 22B) the second fluid passage 92 allows fluid flow between the second and third valve ports 34, 35, while the third fluid passage 96 allows fluid flow between the fourth and fifth valve ports 36, 37. In this position, the first fluid passage 72 is not used, as it does not extend between valve ports. In yet another rotational position of the valve cone assembly 50 with respect to the valve body 20 ( Fig. 23A, Fig. 23B) The third fluid passage 96 allows fluid flow between the second and third valve ports 34, 35. In this position, the first fluid passage 72 and the second fluid passage 92 are not used, as they do not extend between valve ports.

[0052] With reference to Fig. 24 and Fig. 25 comprises a rotary cone valve 218 (not according to the invention), a valve body 220, and a valve cone assembly 250, which is arranged in the valve body 220 and rotates about an axis of rotation 52 therein. Furthermore, the rotary cone valve 218 comprises the valve seal 110, which is arranged in the valve body 220. As in the previous embodiment, the seal 110 provides a fluid-tight seal between the valve body 220 and the valve cone assembly 250.

[0053] The valve body 220 is similar to the valve body 20 described above in that it comprises several valve ports 33, 34, 35, 36, 37, the number of ports being determined by the specific application. However, in the rotary cone valve 218, the valve ports 33, 34, 35, 36, 37 are arranged at a single level (e.g., the valve ports 33, 34, 35, 36, 37 lie in a single plane that is transverse to the axis of rotation 52). The valve body 220 is similar to the valve body 20 described above in that it comprises a base 226 and a side wall 221. The base 226 has a circular profile when viewed in a direction parallel to the axis of rotation 52. The side wall 221 is connected to a circumferential edge of the base 226 at the base end 222 of the side wall, and the side wall 221 surrounds the base 226.The side wall 221 and the base 226 together form a generally cup-shaped structure that defines a valve body chamber 230 within it. The open end 223 of the side wall 221 has a diameter larger than the diameter of the base end 222, with the side wall 221 projecting at an oblique angle θ1 to the base 226. In the illustrated embodiment, the angle θ1 is in a range of 95 to 150 degrees, for example, 97 degrees.

[0054] In the valve body 220, the inner surface of the body side wall 221 is provided with grooves 232 extending between the base end 222 and the open end 223. The grooves 232 have the same cross-sectional shape as the ribs of the seal 110 and are dimensioned to accommodate the ribs of the seal 110 in an interference fit. The number of grooves 232 provided corresponds to the number of ribs of the seal 110. In the illustrated embodiment, the valve body 220 comprises six grooves 232. At least one groove 232 is arranged between the ports of each adjacent pair of valve ports 33, 34, 35, 36, 37.

[0055] The rotary cone valve 218 from Fig. 24 and Fig. The embodiment 25 differs from the previous embodiment in that it includes a cover 240 that closes the open end of the valve body 220. An inner surface 241 of the cover 240 may include an annular groove 242 extending along a periphery of the inner surface 241. The groove 242 is shaped and dimensioned to receive the open end 223 of the body side wall 221, for example, in an interference fit. The inner surface 241 of the cover may also include an annular projection 243 that engages with the first ring 111 of the seal, thereby fluid-tightly connecting the cover 240 to the valve body 220. The annular projection 243 is located between the groove 242 and a center point of the cover 240 at a location adjacent to the groove 242.

[0056] The rotary cone valve 218 from Fig. 24 and Fig. The embodiment 25 differs from the previous embodiment in that it includes a spring 246 which is arranged in the valve body chamber 30 between the cover 240 and the valve cone assembly 250. In the illustrated embodiment, a first end 248 of the spring 246 is received in a centrally positioned blind hole 244 provided on the inner surface 241 of the cover. Furthermore, a second end 249 of the spring 246 surrounds the stem 276. The spring 246 can be a coil spring that is compressed, whereby the spring 246 exerts a force on the valve cone assembly 250, thus ensuring a good seal between the valve cone assembly 250 and the seal 110 and between the seal 110 and the valve body 220.

[0057] The rotary cone valve 218 from Fig. 24 and Fig. The embodiment 25 differs from the previous embodiment in that the valve cone assembly 250 is a one-piece structure defining two fluid passages 272, 292, which allow fluid supply at a single height. The valve cone assembly 250 is similar to the valve cone assembly 50 described above in that it comprises a first base 266 and a first side wall 261. The first base 266 is parallel to the body base 226 and has a circular profile when viewed in a direction parallel to the axis of rotation 52. The first base 266 has an outer surface 267 facing the body base 226 and an opposing inner surface 268 facing away from the body base 226. The first side wall 261 is connected to a circumferential edge of the first base 266 at the base end 262. The first side wall 261 surrounds the first base 266 and is centered on the axis of rotation 52.The first side wall 261 and the first base 266 together form a generally cup-shaped structure. An open end 263 of the first side wall 261 (e.g., the end of the first side wall 261 spaced from the first base 266) has a diameter larger than the diameter of the base end 262, causing the first side wall 261 to project at an oblique angle θ2 to the first base 266. In the example shown, the angle θ2 is in a range of 95 to 150 degrees, for example, 97 degrees.

[0058] The rotary cone valve 218 from Fig. 24 and Fig.25 differs from the previous embodiment in that the base 226 of the valve body 220 comprises a central opening 229, and the valve cone assembly 250 comprises an input shaft 297 that projects outward from the outer surface 267 of the base and extends through the central opening 229 of the base. An annular seal 299 is arranged between the input shaft 297 and the body base 26. The input shaft 297 can be connected to the actuator via a splined connection or other known connection structures, thereby enabling the actuator to drive the valve cone assembly 250 to rotate about the axis of rotation 52.
