Description

[Technical Field]

[0001] The present disclosure relates to a valve for a cooling system. The cooling system includes a valve for controlling the flow of a medium through pipe parts of a piping system. The medium is distributed to a plurality of consumer devices and / or thermal energy exchangers via the piping system. The cooling system can include a common supply source, and the piping system can be connected to the common supply source. [Background technology]

[0002] Several applications are known in commercial and / or industrial and / or residential buildings that utilize pipe systems that distribute media to various consumer devices scattered throughout the building, the media typically originating from a common source.

[0003] A pipe system can be or include a closed circuit, which includes one or more supply pipes connecting a common supply source with each of the consumer devices, and one or more return pipes connecting each of the consumer devices back to the common supply source.

[0004] The consumer device preferably includes a thermal energy exchanger. The consumer device is ideally a thermal energy exchanger. More specifically, the consumer device may include a heat and cold exchange system. The consumer device may even be a heat and cold exchange system.

[0005] The pipe system may also be or include an open circuit. An open circuit includes one or more supply pipes connecting a common supply source to each of the consumer devices. In contrast to a closed circuit, there is no return pipe connecting all the consumer devices back to the common supply source. The pipe system can still be a combination of closed and open circuits.

[0006] These systems can include valves, such as control valves with adjustable orifice systems, for controlling the flow of medium to each consumer device. The position of the adjustable orifice of the adjustable orifice system determines the amount of medium passing through the consumer device per time unit. In a heat and cold exchange application, this means that the position of the orifice determines the amount of cooling delivered from the thermal energy exchanger to an adjacent structure. The adjacent structures preferably include adjacent rooms of a building. The adjacent spaces are ideally adjacent rooms of a building. The adjacent structures can also include adjacent appliances or their spaces. The adjacent structures can still be adjacent appliances or their spaces.

[0007] The flow rate of a medium through a consumer device depends, among other factors, on an adjustable orifice. The adjustable orifice of a valve, such as an expansion valve, includes a valve seat and a valve element (e.g., a plunger). Known adjustable orifices include ball-type adjustable orifices and the orifice of a globe valve.

[0008] The adjustable orifice of the valve functions to allow flow through the valve when the adjustable orifice is in an open position. The adjustable orifice of the valve functions to prevent flow through the valve when the adjustable orifice is in a closed position. In certain applications, the adjustable orifice is expected to close tightly when the adjustable orifice is in a closed position. In other words, when the adjustable orifice is in a closed position, there will be zero flow through the valve.

[0009] The adjustable orifice of a cooling system valve is a mechanical part and, as such, is subject to mechanical wear. The parts of the adjustable orifice, such as the valve element and valve seat, are expected to remain leak-free after many valve cycles. They are also expected to remain leak-free after several years of operation.

[0010] U.S. Patent No. 6,435,207(B1) issued on August 20, 2022. U.S. Patent No. 6,435,207(B1) deals with a flow adjustment fitting. U.S. Patent No. 6,435,207(B1) claims a priority date of December 21, 1996.

[0011] A control system for a pipe system is known from U.S. Pat. No. 6,435,207 (B1). U.S. Pat. No. 6,435,207 (B1) describes a flow regulation control valve for setting and measuring a volumetric flow in a pipe. The flow regulation control valve includes a shutoff member disposed in a flow chamber for setting a desired flow condition. A sensor is disposed in or adjacent to the flow chamber for sensing a value representative of the flow through the flow chamber.

[0012] The flow regulation control valve further includes an evaluation unit that determines the flow from the signal recorded by the sensor and from characteristic values of the control valve, which are stored in an electronic data store in the sensor and are valve-specific. The flow rate through the section of the pipe system is manually adjusted using a shutoff member of the flow regulation control valve. The flow rate is adjusted until the desired flow is indicated by the evaluation unit.

[0013] Patent application WO98 / 25086A1 was filed on December 4, 1997. The application was published on June 11, 1998. A priority date of December 4, 1996 is claimed. WO98 / 25086A1 discloses a modulated fluid control device for a fluid-based heating and cooling system for a measured environment.

[0014] The control device includes a body, a supply port, a return port, and a valve positioned between the ports. The valve is connected to an actuator. The actuator and valve respond to inputs from the sensor and from the controller. The flow of media through the valve is thereby restricted, the restriction depending on the conditions in the measured environment. The control device is provided with a valve controller and actuator to position the valve, thereby regulating the flow through the valve. A flow sensor is associated with the valve and records the flow of media at a predetermined location in the system. The flow sensor provides a signal indicative of the flow rate to the valve controller. The flow sensor and valve controller maintain the required flow rate through the system as recorded by the sensor. The system thereby promotes desired environmental conditions in the space.

[0015] European Patent Application EP3839308A1 was filed by SIEMENS SCHWEIZ AG on December 20, 2019. The application was published on June 23, 2021. EP3839308A1 addresses an expansion valve. The valve includes an inlet port, an outlet port, and an adjustable orifice located in a fluid path between the inlet and outlet ports. The adjustable orifice system corresponds to a globe valve and includes an adjustable orifice and an armature. An electric current through a solenoid causes movement of the armature and the adjustable orifice. The solenoid is directly immersed in the coolant.

An adapter fitting secures the replaceable cartridge to the body of the valve. The cartridge also provides a diffuser at its outer end. The valve plunger engages the valve element of the replaceable cartridge.

[0019] [Patent Document 1] U.S. Patent No. 6,435,207(B1) [Patent Document 2] International Publication No. 98 / 25086A1 Brochure [Patent Document 3] European Patent Application Publication No. 3839308A1 [Patent Document 4] U.S. Patent No. 5,419,365(A) [Patent Document 5] US Patent No. 11835145 (B2) [Patent Document 6] US Patent Application Publication No. 2020 / 347952(A1) Summary of the Invention [Problem to be solved by the invention]

[0020] The present disclosure deals with a valve for a refrigeration system, which may be, by way of example, an expansion valve in a refrigeration system, having an improved adjustable orifice in the valve. [Means for solving the problem]

[0021] The adjustable orifice of the disclosed valve includes a valve member in the form of a plunger. The adjustable orifice also includes a valve seat assembly having a valve seat in the form of a gasket. The plunger cooperates with the gasket to close and open the valve. More specifically, in the closed position, the plunger abuts the gasket. In the open position, the plunger is removed from the gasket.

[0022] The tip of the plunger has the shape of a receptacle with the head portion facing the gasket. A lip is provided at the end of the head. In the closed position, the lip abuts the gasket, thereby closing the valve. The shape of the plunger allows for well-defined closing and opening characteristics.

[0023] The plunger and gasket can be made from materials that ensure a long life. For example, the plunger can be made from a metal such as (stainless) steel, while the gasket is made from a polymer material. The gasket material is generally more ductile than the material of the (circular edge of) the plunger.

[0024] To arrive at a more universal solution, adapters, such as flow control adapters, are used. The adapters are part of the valve seat assembly, i.e., various adapters can be used on the valve and the valve remains unchanged except for the adapter.

[0025] Although the valve member and / or plunger are moving parts, the gasket is not configured to move during operation of the valve.

[0026] Similar to a gasket, an adapter provides an aperture and / or bore to allow fluid flow between the ports of the valve. The fluid can be a coolant fluid. It can be liquid and / or gaseous. The fluid can also be superheated.

[0027] The adapter provides an inner surface that surrounds the aperture and / or bore of the adapter. In operation, the plunger moves linearly along the inner surface of the adapter, thereby opening and / or restricting fluid flow. More specifically, the outer surface of the plunger moves along the inner surface of the flow control adapter to regulate fluid flow.

[0028] One or more recesses can be located along the inner surface of the flow control adapter. The one or more recesses increase fluid flow when the valve is in the open position, such that fluid flows laterally along the tip of the plunger and into a first end of the one or more recesses.

[0029] The fluid then flows through the one or more recesses toward a second end of the one or more recesses, the second end being different from the first end, the second end facing toward the gasket, while the first end facing toward the linear actuator of the valve.

[0030] As the fluid exits the one or more recesses, it will flow towards the gasket and then towards the second port of the valve.

[0031] The valve can be used in more than one direction. Fluid can flow from the second port of the valve toward the gasket and then toward the flow control adapter. That is, fluid enters one or more recesses at the second end of the one or more recesses. Fluid will flow through the one or more recesses and exit one or more recesses at the first end of the one or more recesses. Finally, fluid will flow toward the linear actuator and toward the first port of the valve.

[0032] Various symmetrical and asymmetrical arrangements of the adapter's recess(es) can be selected to accommodate the valve. Thus, the valve can be adapted according to the nuances of its application in the coolant circuit. As a non-limiting example, the valve can be used as an expansion valve in the coolant circuit.

[0033] Various features will become apparent to those skilled in the art from the following detailed description of the disclosed non-limiting embodiments. The drawings that accompany the detailed description can be briefly described as follows: [Brief explanation of the drawings]

[0034] [Figure 1] FIG. 1 is a schematic diagram of a valve, such as a valve for a cooling circuit. [Figure 2] FIG. 2 depicts details of the valve seat assembly of the valve shown in FIG. 1. [Figure 3] FIG. 1 is a top view of a flow control adapter. [Figure 4] FIG. 10 illustrates a cross section of the same flow control adapter. [Figure 5] 10A and 10B illustrate another cross section of the same flow control adapter. [Figure 6] 4 is a top view of another flow control adapter different from the flow control adapter of FIG. 3. [Figure 7] FIG. 10 is a top view of yet another flow control adapter having unevenly distributed recesses and / or cutouts and / or slots. DETAILED DESCRIPTION OF THE INVENTION

[0035] 1 illustrates various components of a valve 1 of the present disclosure. Valve 1 is advantageously or includes an expansion valve. More advantageously, valve 1 is or includes an electronic expansion valve. Valve 1 can be installed in a refrigeration-steam circuit. Valve 1 according to at least one embodiment is advantageously part of a refrigeration-steam circuit.

[0036] Valve 1 includes a housing 2. Valve housing 2 has sides defining a first port 3 and a second port 4. In one embodiment, first port 3 includes a first conduit. It is also envisioned that second port 4 includes a second conduit. According to one aspect of the present disclosure, first port 3 is an inlet port and second port 4 is an outlet port. According to another aspect of the present disclosure, first port 3 is an outlet port and second port 4 is an inlet port.

[0037] It is envisioned that the valve body is or includes a housing 2. In one embodiment, the housing 2 includes a metallic material such as, for example, steel, particularly austenitic (stainless) steel and / or ferritic steel. In an alternative embodiment, the housing 2 includes aluminum (alloy) or gunmetal or brass. In yet another alternative embodiment, the housing 2 includes a polymeric material. According to one aspect, the housing 2 is manufactured using an additive manufacturing technique such as three-dimensional printing. Manufacturing of the housing 2 can involve selective laser sintering in certain embodiments. It is still envisioned that the housing 2 includes a gray cast material.

[0038] The first port 3 and the second port 4 are in fluid communication with each other to provide for the flow of fluid through the valve 1. In a preferred embodiment, the fluid comprises a refrigerant. The fluid may be, by way of non-limiting example, R32, R134a, R290, R410A, R450A, R452A, R513A, R454C, R1234yf, or R1234ze(E) refrigerant. The fluid at the inlet port is advantageously a liquid and / or gaseous fluid. The fluid at the outlet port is preferably a two-phase fluid.

[0039] A fluid pathway extends between the first port 3 and the second port 4. A plunger 5 is located within the fluid pathway. The plunger 5 is linearly movable. The plunger 5 may also be axially movable. The plunger 5 cooperates with a valve seat assembly 6. The plunger 5 thereby varies and restricts the flow rate of fluid through the valve 1.

[0040] The plunger 5 includes a head portion. The head portion protrudes from the plunger 5. Ideally, the head portion protrudes from the plunger 5 in the direction of the valve seat assembly 6. According to one embodiment, the plunger 5 includes a body portion. The head portion protrudes from the body portion of the plunger 5. Ideally, the head portion protrudes from the body portion of the plunger 5 in the direction of the valve seat assembly 6. The head portion of the plunger 5 and the body portion of the plunger 5 may be integral.

[0041] According to one embodiment, the plunger 5 includes a receptacle portion. A head portion protrudes from the receptacle portion of the plunger 5. Ideally, the head portion protrudes from the receptacle portion of the plunger 5 toward the valve seat assembly 6. The receptacle portion of the plunger 5 and the body portion of the plunger 5 may be integral.

[0042] The plunger 5 includes an end that faces the valve seat assembly 6. The end of the plunger 5 can have the shape of a receptacle and / or an inverted bowl. The end of the plunger 5 can be shaped such that the opening of the receptacle faces the valve seat assembly 6.

[0043] Advantageously, the head portion includes an end facing the valve seat assembly 6. Ideally, the head portion is the end facing the valve seat assembly 6. The end of the plunger 5 and / or the end of the head portion may include a circular edge facing the valve seat assembly 6. The edge may be a sharp edge having an acute angle, i.e., the edge tapers towards the valve seat assembly 6, the taper defining an acute angle. By way of example, the acute angle may be less than 20 degrees, or less than 10 degrees, or even less than 5 degrees.

[0044] The edge at the end of the plunger 5 is preferably a rim or includes a rim. The edge at the end of the plunger 5 follows a closed, continuous line. It is also possible for the edge at the end of the plunger 5 to follow a closed, continuous circle.

[0045] 1 shows the valve seat assembly 6 as part of the second port 4. Those skilled in the art, having reviewed the embodiments disclosed herein, will understand that the first port 3 can also include the valve seat assembly 6. Those skilled in the art will also understand that the assembly 6 can be separate from the first port 3 and can also be separate from the second port 4.

[0046] In the embodiment shown in FIG. 1 , the plunger 5 is linearly movable by linear movement of the armature 7. The axial direction is defined by the linear movement of the plunger 5; that is, the plunger 5 is axially movable by axial movement of the armature 7. The armature 7 may be mechanically connected to the plunger 5 via a stem 8. It is also envisioned that the armature 7 connects directly to the plunger 5. It is still envisioned that the armature 7 and the plunger 5 are one piece.

[0047] According to one embodiment of the present disclosure, the armature 7, the stem 8, and the plunger 5 are integral. That is, the stem 8 and the plunger 5 are both integral parts of the armature 7. Similarly, the armature 7 and the stem 8 are integral with the plunger 5.

[0048] According to another aspect of the present disclosure, the plunger 5 is configured to rotate only to a certain extent relative to the armature 7. The plunger 5 preferably rotates about an axis connecting the armature 7, the plunger 5, and / or the stem 8. In one embodiment, the plunger 5 is allowed to rotate by 0.1 degrees of articulation, or 0.2 degrees of articulation, or even 0.5 degrees of articulation. The limited amount of articulation of the plunger 5 relative to the armature 7 improves alignment of the arrangement.

[0049] At least a portion of the armature 7 may be surrounded by solenoids 9a, 9b. When an electric current is applied, the solenoids 9a, 9b create a magnetic flux that acts on the armature 7, thereby displacing it.

[0050] 1 shows valve 1 with a solenoid actuator. It is envisioned that other actuators, such as hydraulic or pneumatic actuators, may also be used to actuate stem 8 and plunger 5. Valve 1 may also be actuated by a magnetic piston pump. This list of actuators is not exhaustive.

[0051] A tubular portion, such as a can, need not encase the armature 7 and / or stem 8. That is, the armature 7 has an outer surface. In one embodiment, a portion of the outer surface of the armature 7 directly faces the solenoids 9a, 9b. In another embodiment, the outer surface of the armature 7 directly faces the solenoids 9a, 9b. Similarly, the solenoids 9a, 9b have outer surfaces. In one embodiment, a portion of the outer surface of the solenoids 9a, 9b directly faces the armature 7. In another embodiment, the outer surfaces of the solenoids 9a, 9b directly face the armature 7.

[0052] The solenoids 9a, 9b and the armature 7 are located within the same chamber 10 inside the housing 2. The chamber 10 is ideally filled with a liquid and / or gaseous fluid. The liquid and / or gaseous fluid inside the chamber 10 can be, by way of non-limiting example, R32, R134a, R290, R410A, R450A, R452A, R513A, R454C, R1234yf, or R1234ze(E) refrigerants.

[0053] This liquid and / or gaseous fluid is in direct contact with the outer surface of the portion of the armature 7 that is inside the chamber 10. The liquid and / or gaseous fluid is also in direct contact with the solenoids 9a, 9b.

[0054] According to one aspect of the present disclosure, solenoids 9a, 9b include multiple coils. It is envisioned that at least one coil, at least two coils, or at least five coils of solenoids 9a, 9b are directly exposed to the liquid and / or gaseous fluid in chamber 10a. In certain embodiments, all coils of solenoids 9a, 9b are directly exposed to the liquid and / or gaseous fluid. Solenoids 9a, 9b preferably include helical solenoids.

[0055] The resilient member 11 ensures that the valve 1 is a normally closed valve. The resilient member 11 is coupled to the armature 7. In certain embodiments, the resilient member 11 is mechanically connected to the armature 7.

[0056] The resilient member 11 biases the armature 7 and plunger 5 to close the valve 1. To that end, the resilient member 11 biases the armature 7 and plunger 5 toward the seat assembly 6. In a particular embodiment, the resilient member 11 biases the armature 7, stem 8, and plunger 5 to close the valve 1. To that end, the resilient member 11 biases the armature 7, stem 8, and plunger 5 toward the seat assembly 6. The member 11 preferably biases these movable members 7, 8, 5 toward the assembly 6 until the plunger 5 engages a cooperating member of the assembly 6. The plunger 5 is advantageously engaged with a cooperating member of the assembly 6 in the closed position of the valve 1.

[0057] According to one aspect, the resilient member 11 comprises a compression spring. In one embodiment, the resilient member 11 comprises a compression helical spring.

[0058] 1 shows a resilient member 11 in the form of a spring. It is envisioned that other resilient members, such as ferromagnetic members, bias the armature 7 and plunger 5 to close the valve 1. It is envisioned that other resilient members, such as ferromagnetic members, bias the armature 7, stem 8, and plunger 5 to close the valve 1. This list of resilient members is not exhaustive.

[0059] 2, details of the valve seat assembly 6 of the valve 1 are shown. The valve seat assembly 6 includes a gasket 12, such as an annular seal. The gasket 12 can be made from a resilient material, such as a polymeric material and / or a rubber material. The gasket 12 can be made from a polymeric material including, by way of non-limiting example, at least one of the following: - polytetrafluoroethylene, - Polyetheretherketone. The polymeric material including polytetrafluoroethylene may also include graphite particles, such as spherical graphite. The gasket 12 can be made from a polymeric material selected from the following, as other non-limiting examples: - polytetrafluoroethylene, or - Polyetheretherketone. Gasket 12 provides an aperture to allow fluid flow to or from first port 3. Similarly, gasket 12 provides an aperture to allow fluid flow to or from second port 4.

[0060] The apertures and / or orifices in the gasket 12 are such that the plunger 5 cannot move into or out of the apertures and / or orifices in the gasket 12. In other words, the gasket 12 ultimately stops or inhibits the movement of the plunger 5. That is, the inner diameters of the apertures and / or orifices in the gasket 12 are smaller than the outer diameters of the plunger 5. More specifically, the inner diameters of the apertures and / or orifices can be smaller than the outer diameter of the rim of the plunger 5. The inner diameters of the apertures and / or orifices can also be smaller than the outer diameter of the rim of the plunger 5. The inner diameters of the apertures and / or orifices can still be smaller than the outer diameter of the head portion of the plunger 5.

[0061] In one embodiment, the gasket 12 has cylindrical symmetry. It is also envisioned that the second port 4 also has cylindrical symmetry. Ideally, both the gasket 12 and the second port 4 have cylindrical symmetry. The gasket 12 and the second port 4 may even exhibit cylindrical symmetry about the same axis, or about substantially the same axis. This axis is advantageously defined by the linear movement of the plunger 5. This axis may also be defined by the axial movement of the plunger 5.

[0062] In a particular embodiment, both the gasket 12 and the aperture of the gasket 12 have cylindrical symmetry. The gasket 12 and the aperture of the gasket 12 can even exhibit cylindrical symmetry about the same axis, or about substantially the same axis. This axis is advantageously defined by the linear movement of the plunger 5. This axis can also be defined by the axial movement of the plunger 5.

[0063] The gasket 12 can be mechanically attached to the frame 13, which in turn mechanically connects the gasket 12 to the second port 4. It is assumed that the frame 13 and the gasket 12 present parallel surfaces. These parallel surfaces are perpendicular to the direction of flow through the second port 4 and / or to the axis of symmetry of the second port 4. These parallel surfaces are also respectively perpendicular to the axial direction defined by (the movement of) the plunger 5. It is assumed that the parallel surfaces of the gasket 12 abut against the parallel surfaces of the frame 13, i.e., the gasket 12 sits on the frame 13.

[0064] In one embodiment, the frame 13 comprises a metallic material such as steel. The steel material can be selected from, by way of non-limiting example, the following: - austenitic steel, - ferritic steel, - stainless steel. In alternative embodiments, frame 13 comprises aluminum (alloy), gunmetal, or brass. In yet another alternative embodiment, frame 13 comprises a polymer material. According to one aspect, frame 13 is manufactured using additive manufacturing techniques such as three-dimensional printing. Manufacturing of frame 13 may involve selective laser sintering in certain embodiments. It is still envisioned that frame 13 comprises a gray cast material.

[0065] According to one embodiment of the present disclosure, the housing 2 and the frame 13 are made from the same material.

[0066] The valve seat assembly 6 also includes flow control adapters 14a, 14b. The flow control adapters 14a, 14b are positioned such that the gasket 12 is disposed between the flow control adapters 14a, 14b and the valve port 4. In one embodiment, the gasket 12 is disposed between the flow control adapters 14a, 14b and the parallel surfaces of the frame 13.

[0067] The flow control adapters 14a, 14b can be mechanically attached to the frame 13. The frame 13 thus mechanically connects the flow control adapters 14a, 14b to the second port 4. It is assumed that the flow control adapters 14a, 14b and the gasket 12 present parallel surfaces that are perpendicular to the direction of flow through the second port 4 and / or to the axis of symmetry of the second port 4. These parallel surfaces are also perpendicular to the axial direction defined by the movement of the plunger 5. It is assumed that the parallel surfaces of the gasket 12 abut against the parallel surfaces of the flow control adapters 14a, 14b.

[0068] That is, the gasket 12 has a first surface and a second surface, and the second surface is different from the first surface. The second surface and the first surface of the gasket 12 are parallel. The first surface of the gasket 12 and the second surface of the gasket 12 are disposed on opposite sides of the gasket 12. The first surface of the gasket 12 abuts the frame 13. The second surface of the gasket 12 abuts the flow control adapters 14a, 14b. The gasket 12 is advantageously sandwiched between (a part of) the frame 13 and the flow control adapters 14a, 14b. In addition, in the closed position, the second surface of the gasket 12 also abuts the plunger 5 and / or the head portion of the plunger 5.

[0069] In operation, the gasket 12 may cooperate with the plunger 5 to close or open the valve 1. More specifically, the gasket 12 cooperates with a cooperating portion of the plunger 5. The cooperating portion of the plunger 5 may be selected from at least one of the following: - the edge of the plunger 5, - rim of plunger 5, - Head part of plunger 5.

[0070] The gasket 12 can be made from a material that is more ductile than the material of the cooperating portion of the plunger 5. At temperatures below 433 Kelvin, the material of the gasket 12 is more ductile than the material of the cooperating portion. The material of the gasket 12 is also more ductile than the material of the cooperating portion at temperatures above 213 Kelvin. In other words, the gasket 12 can be deformed while the valve 1 is in operation.

[0071] In particular embodiments, the flow control adapters 14a, 14b comprise aluminum (alloy), gunmetal, or brass. In yet another particular embodiment, the flow control adapters 14a, 14b comprise a polymer material. The material of the flow control adapters 14a, 14b can also be selected from the following, by way of non-limiting example: - austenitic steel, - ferritic steel, - stainless steel.

[0072] The flow control adapters 14a, 14b provide apertures and / or orifices to allow fluid flow toward or from the first port 3. Similarly, the flow control adapters 14a, 14b provide apertures and / or orifices to allow fluid flow toward or from the second port 4. The apertures and / or orifices of the adapters 14a, 14b provide linear movement of the plunger 5 into and out of the apertures and / or orifices. The apertures and / or orifices of the adapters 14a, 14b also provide axial movement of the plunger 5 into and out of the apertures and / or orifices. That is, the inner diameter of the apertures and / or orifices of the adapters 14a, 14b is larger than the outer diameter of the plunger 5. More specifically, the inner diameter of the apertures and / or orifices can be larger than the outer diameter of the edge of the plunger 5. The inner diameter of the aperture and / or orifice may also be larger than the outer diameter of the rim of the plunger 5. The inner diameter of the aperture and / or orifice may still be larger than the outer diameter of the head portion of the plunger 5.

[0073] In one embodiment, the plunger 5 is capable of linearly moving in the direction of flow a distance between zero and 10 millimeters. More preferably, the plunger 5 is capable of linearly moving in the direction of flow a distance between zero and 5 millimeters. Even more preferably, the plunger 5 is capable of linearly moving in the direction of flow a distance between zero and 3 millimeters. The small travel distance of the plunger 5 results in a valve 1 that requires modest resources from an actuation perspective.

[0074] In a related embodiment, the plunger 5 is capable of axial movement in the direction of flow a distance between zero and 10 millimeters. More preferably, the plunger 5 is capable of axial movement in the direction of flow a distance between zero and 5 millimeters. Even more preferably, the plunger 5 is capable of axial movement in the direction of flow a distance between zero and 3 millimeters. The small travel distance of the plunger 5 results in a valve 1 that requires modest resources in terms of operation.

[0075] The flow control adapters 14a, 14b form separate parts from the frame 13 and from the gasket 12. The flow control adapters 14a, 14b may even be mechanically separable from the frame 13 and from the gasket 12. Separation is preferably non-destructive. That is, various flow control adapters 14a, 14b may be used with the same frame 13 and the same gasket 12. More specifically, the various flow control adapters 14a, 14b may be attached to and / or fitted to the same frame 13. For example, the various flow control adapters 14a, 14b may be threadedly attached and / or glued and / or shrink-fitted to the frame 13. The various flow control adapters 14a, 14b may be interference-fitted to the frame 13, as another non-limiting example. The various flow control adapters 14a, 14b may be caulked to the frame 13, as yet another non-limiting example. The valve 1 can be more easily constructed when various flow control adapters 14a, 14b can be mounted on the same frame 13. By interchanging the flow control adapters 14a, 14b, a large amount of flow rate through the valve can be achieved.

[0076] In the embodiment shown in FIGS. 1 and 2, the flow control adapters 14a, 14b are diffusers and have rotational symmetry. The flow control adapters 14a, 14b as shown in FIG. 1 include an inner portion having a beveled surface. The surface of the inner portion is preferably both beveled and smooth. It is also envisioned that the cooperating portion of the plunger 5 has rotational symmetry. Ideally, the flow control adapters 14a, 14b and the cooperating portion of the plunger 5 both have rotational symmetry. It is also envisioned that the rim of the cooperating portion of the plunger 5 has rotational symmetry. Ideally, the rim of the flow control adapters 14a, 14b and the cooperating portion of the plunger 5 both have rotational symmetry. It is still envisioned that the edge of the cooperating portion of the plunger 5 has rotational symmetry. Ideally, the edge of the cooperating portion of the flow control adapters 14a, 14b and the cooperating portion of the plunger 5 both have rotational symmetry. In one embodiment, the head portion of plunger 5 has rotational symmetry. Ideally, both flow control adapters 14a, 14b and the head portion of plunger 5 have rotational symmetry.

[0077] The cooperating portions of the flow control adapters 14a, 14b and the plunger 5 may even exhibit rotational symmetry about (substantially) the same axis. The rims of the cooperating portions of the flow control adapters 14a, 14b and the plunger 5 may still exhibit rotational symmetry about (substantially) the same axis. The edges of the cooperating portions of the flow control adapters 14a, 14b and the plunger 5 may still exhibit rotational symmetry about (substantially) the same axis. In one embodiment, the head portions of the flow control adapters 14a, 14b and the plunger 5 exhibit rotational symmetry about (substantially) the same axis.

[0078] Turning now to Figure 3, a configuration is shown in which flow control adapter 14c no longer has perfect cylindrical or rotational symmetry. Flow control adapter 14c as illustrated in Figure 3 is viewed from above, while flow control adapters 14a, 14b illustrated in Figure 2 are viewed from the side. More specifically, Figure 2 provides a cross-sectional view of flow control adapters 14a, 14b.

[0079] Instead of having perfect rotational symmetry, the symmetry of the flow control adapter 14c shown in FIG. 3 is bi-folded about plane 15. That is, the flow control adapter 14c has reflection symmetry about plane 15. In contrast to the flow control adapters 14a, 14b depicted in FIG. 2, the surfaces 16 of the flow control adapter 14c are preferably not angled. Also, the surfaces 16, such as the top surface of the flow control adapter 14c, are preferably not frusto-conical. The top surface of the flow control adapter 14c faces away from the second port 4.

[0080] The two recesses 17a, 17b break the perfect rotational symmetry of the flow control adapter 14c, as shown in Figure 3. In operation, a fluid, such as a coolant, can flow between the plunger 5 and the adapter 14c through the recesses 17a, 17b. Thus, the recesses 17a, 17b allow limited flow between the plunger 5 and the adapter 14c.

[0081] That is, a fluid, such as a coolant, will flow laterally between the plunger 5 and the recesses 17a, 17b. Fluid flow is preferably permitted laterally between the outer cylindrical surface of the plunger 5 and the recesses 17a, 17b. The fluid will then continue to flow toward one of the ports 3, 4 of the valve 1. The flow will vary as the plunger 5 moves linearly between the closed and open positions of the valve 1. The flow will also vary as the plunger 5 moves axially between the closed and open positions of the valve 1. The flow will be zero when the plunger 5 is in the closed position.

[0082] According to one embodiment of the present disclosure, recesses 17a, 17b include cutouts. According to one embodiment of the present disclosure, recesses 17a, 17b are cutouts. Advantageously, both recesses 17a, 17b as shown in FIG. 3 are cutouts.

[0083] According to one embodiment of the present disclosure, the recesses 17a, 17b include slots. According to one embodiment of the present disclosure, the recesses 17a, 17b are slots. Advantageously, both recesses 17a, 17b as shown in FIG. 3 are slots.

[0084] The depressions 17a, 17b exhibit reflection symmetry with respect to the plane 15. In a special embodiment, the depressions 17a, 17b exhibit reflection symmetry with respect to the plane 18. The plane 18 is advantageously perpendicular to the plane 15.

[0085] The flow control adapter 14c provides an aperture and / or orifice to allow fluid flow toward or from the first port 3. Similarly, the flow control adapter 14c provides an aperture and / or orifice to allow fluid flow toward or from the second port 4. The aperture and / or orifice of the flow control adapter 14c provides linear movement of the plunger 5 into and out of the aperture and / or orifice. The aperture and / or orifice of the adapter 14c also provides axial movement of the plunger 5 into and out of the aperture and / or orifice. That is, the inner diameter 19 of the aperture and / or orifice of the adapter 14c is larger than the outer diameter of the plunger 5. More specifically, the inner diameter 19 of the aperture and / or orifice can be larger than the outer diameter of the edge of the plunger 5. It is also possible that the inner diameter 19 of the aperture and / or orifice is larger than the outer diameter of the rim of the plunger 5 .

[0086] The material options for flow control adapter 14c are the same as those for flow control adapters 14a, 14b.

[0087] Due to its beveled or inverted frustoconical surface, the flow control adapters 14a, 14b of FIG. 2 provide greater flow than the adapter 14c of FIG. 3. The flow control adapter 14c no longer has a beveled surface with perfect rotational symmetry. Instead, recesses 17a, 17b and / or cutouts 17a, 17b and / or slots 17 allow flow. However, these recesses 17a, 17b and / or cutouts 17a, 17b and / or slots 17 do not provide flow along the entire periphery of the flow control adapter 14c. As a result, the flow values through the flow control adapter 14c tend to be smaller than the flow values through the flow control adapters 14a, 14b. Comparisons of flow coefficients between these embodiments apply at a constant pressure drop and for a constant inner diameter of the flow control adapter 14c.

[0088] The flow control adapter 14c advantageously forms a separate part from the frame 13 and from the gasket 12. The flow control adapter 14c may even be mechanically separable from both the frame 13 and the gasket 12. Separation is preferably non-destructive. That is, various flow control adapters 14a-14c can be used with the same frame 13 and the same gasket 12. More specifically, the various flow control adapters 14a-14c can be attached and / or fitted to the same frame 13. For example, the various flow control adapters 14a-14c can be threaded and / or glued and / or shrink-fitted to the frame 13. When the various flow control adapters 14a-14c can be attached to the same frame 13, the valve 1 can be more easily constructed. By exchanging the flow control adapter 14c, a greater amount of flow rate through the valve can be achieved.

[0089] 4, there is shown a cross section of the same flow control adapter 14. The cross section of FIG. 4 is taken along plane 15 as shown in FIG.

[0090] Two recesses 17a, 17b and / or cutouts 17a, 17b and / or slots 17a, 17b are located on either side of the flow control adapter 14. In the exemplary embodiment shown in Figure 4, the cross-sections of these recesses 17a, 17b and / or cutouts 17a, 17b and / or slots 17a, 17b have arcuate profiles. These arcs connect surface 16 of the adapter 14c to another parallel surface of the flow control adapter 14c, the other surface being opposite the first surface.

[0091] It is also envisioned that the profiles of these recesses 17a, 17b and / or cutouts 17a, 17b and / or slots 17a, 17b can be triangular. The straight lines of these triangles connect first surface 16 of adapter 14c to a second parallel surface of flow control adapter 14c. The second of these surfaces is disposed opposite first surface 16 and is parallel to the first surface. It is still envisioned that the profiles of recesses 17a, 17b and / or cutouts 17a, 17b and / or slots 17a, 17b include a step.

[0092] 5, another cross section of the same flow control adapter 14c is shown, the cross section of FIG. 5 being a different cross section than the cross section of FIG. 4, and taken along plane 18 as shown in FIG.

[0093] Two polygonal sections 20a, 20b are located on either side of the flow control adapter 14. The polygonal profiled sections 20a, 20b are part of the tubular bulk of the flow control adapter 14c. The sections 20a, 20b are distinct from the recesses 17a, 17b and / or cutouts 17a, 17b and / or slots 17a, 17b of the flow control adapter 14c.

[0094] 5, portions 20a, 20b have rectangular profiles. It is also envisioned that portions 20a, 20b could have square-like profiles.

[0095] According to one aspect of the present disclosure, surface 16 can be structured to modify the mechanical properties of flow control adapter 14c. For example, surface 16 can be structured to address stresses and strains inside flow control adapter 14c. Surface 16 can also be structured to modify the flow characteristics of flow control adapter 14c.

[0096] Each of the flow control adapters 14a-14c may include fewer than two recesses 17a, 17b. More specifically, each of the flow control adapters 14a-14c may include a single recess 17a, 17b. Similarly, each of the flow control adapters 14a-14c may include fewer than two cutouts 17a, 17b. More specifically, each of the flow control adapters 14a-14c may include a single cutout 17a, 17b. Also, each of the flow control adapters 14a-14c may include fewer than two slots 17a, 17b. More specifically, each of the flow control adapters 14a-14c may include a single slot 17a, 17b.

[0097] The flow control adapters 14a-14c may include more than two recesses 17a, 17b. Similarly, the flow control adapters 14a-14c may include more than two cutouts 17a, 17b. The flow control adapters 14a-14c may also include more than two slots 17a, 17b.

[0098] The number of recesses 17a-17d and / or cutouts 17a-17d and / or slots 17a-17d generally corresponds to the flow rate to be achieved.

[0099] FIG. 6 shows a flow control adapter 14d including four recesses 17a-17d and / or four cutouts 17a-17d and / or four slots 17a-17d. The recesses 17a-17d and / or cutouts 17a-17d and / or slots 17a-17d as shown in FIG. 5 are arranged symmetrically. The arrangement as depicted in FIG. 5 has four-fold symmetry. In other words, the flow control adapter 14d of FIG. 5 would have the same appearance after being rotated 90 degrees about an axis. In this case, the axis of symmetry is the intersection of planes 15 and 18.

[0100] Also, flow control adapter 14d of FIG. 6 has reflection symmetry about planes 15 and 18.

[0101] The flow control adapter 14d provides an aperture and / or orifice to allow fluid flow toward or from the first port 3. Similarly, the flow control adapter 14d provides an aperture and / or orifice to allow fluid flow toward or from the second port 4. The aperture and / or orifice of the flow control adapter 14d provides linear movement of the plunger 5 into and out of the aperture and / or orifice. The aperture and / or orifice of the adapter 14d also provides axial movement of the plunger 5 into and out of the aperture and / or orifice. That is, the inner diameter 19 of the aperture and / or orifice of the adapter 14d is larger than the outer diameter of the plunger 5. More specifically, the inner diameter 19 of the aperture and / or orifice can be larger than the outer diameter of the edge of the plunger 5. It is also possible that the inner diameter 19 of the aperture and / or orifice is larger than the outer diameter of the rim of the plunger 5 .

[0102] The material choices for flow control adapter 14d are the same as those for flow control adapters 14a, 14b and for flow control adapter 14c.

[0103] Due to its beveled or inverted frustoconical surface, the flow control adapters 14a, 14b of FIG. 2 provide greater flow than the adapter 14d of FIG. 3. The flow control adapter 14d no longer has a beveled surface with perfect rotational symmetry. Instead, recesses 17a, 17b and / or cutouts 17a, 17b and / or slots 17 allow flow. However, these recesses 17a, 17b and / or cutouts 17a, 17b and / or slots 17 do not provide flow along the entire periphery of the flow control adapter 14d. As a result, the flow values through the flow control adapter 14d tend to be smaller than the flow values through the flow control adapters 14a, 14b. Comparisons of flow coefficients between these embodiments apply at a constant pressure drop and for a constant inner diameter of the flow control adapter 14d.

[0104] The flow control adapter 14d advantageously forms a separate part from the frame 13 and from the gasket 12. The flow control adapter 14d may even be mechanically separable from both the frame 13 and the gasket 12. Separation is preferably non-destructive. That is, various flow control adapters 14a-14d can be used with the same frame 13 and the same gasket 12. More specifically, the various flow control adapters 14a-14d can be attached and / or fitted to the same frame 13. For example, the various flow control adapters 14a-14d can be threaded and / or glued and / or shrink-fitted to the frame 13. When the various flow control adapters 14a-14d can be attached to the same frame 13, the valve 1 can be more easily constructed. By exchanging the flow control adapter 14d, a greater amount of flow rate through the valve can be achieved.

[0105] The recesses 17a-17d shown in Figures 3 and 6 are symmetrically distributed along the tubular portion of each flow control adapter 14c, 14d. Similarly, the cutouts 17a-17d shown in Figures 3 and 6 are symmetrically distributed along the tubular portion of each flow control adapter 14c, 14d. Also, the slots 17a-17d shown in Figures 3 and 6 are symmetrically distributed along the tubular portion of each flow control adapter 14c, 14d.

[0106] A symmetrical arrangement offers advantages in terms of a well-defined flow profile. However, there are practical cases where such a flow profile is undesirable. For example, flow measurements with ultrasonic sensors may require turbulent flow.

[0107] 7 illustrates a flow adapter 14e in which recesses 17a, 17b, and 17e are not symmetrically distributed along the tubular portion of adapter 14e. More specifically, recesses 17a, 17b, and 17e are not symmetrically distributed about the axis defined by the intersection of planes 15 and 18. Flow adapter 14e must be rotated 360 degrees about the axis defined by the intersection of planes 15 and 18 until it appears the same.

[0108] 7 also illustrates a flow adapter 14e in which cutouts 17a, 17b, and 17e are not symmetrically distributed along the tubular portion of adapter 14e. More specifically, cutouts 17a, 17b, and 17e are not symmetrically distributed about the axis defined by the intersection of planes 15 and 18. Flow adapter 14e must be rotated 360 degrees about the axis defined by the intersection of planes 15 and 18 until it appears the same.

[0109] 7 still shows flow adapter 14e in which slots 17a, 17b, and 17e are not symmetrically distributed along the tubular portion of adapter 14e. More specifically, slots 17a, 17b, and 17e are not symmetrically distributed about the axis defined by the intersection of planes 15 and 18. Flow adapter 14e must be rotated 360 degrees about the axis defined by the intersection of planes 15 and 18 until it appears the same.

[0110] The flow control adapter 14e provides an aperture and / or orifice to allow fluid flow toward or from the second port 4. The aperture and / or orifice of the flow control adapter 14e provides linear movement of the plunger 5 into and out of the aperture and / or orifice. The aperture and / or orifice of the adapter 14e also provides axial movement of the plunger 5 into and out of the aperture and / or orifice. That is, the inner diameter 19 of the aperture and / or orifice of the adapter 14e is larger than the outer diameter of the plunger 5. More specifically, the inner diameter 19 of the aperture and / or orifice can be larger than the outer diameter of the rim of the plunger 5. The inner diameter 19 of the aperture and / or orifice can also be larger than the outer diameter of the rim of the plunger 5.

[0111] The material options for flow control adapter 14e are the same as those for flow control adapters 14a-14d.

[0112] Due to its beveled or inverted frustoconical surface, the flow control adapters 14a, 14b of FIG. 2 provide greater flow than the adapter 14e of FIG. 3. The flow control adapter 14e no longer has a beveled surface with perfect rotational symmetry. Instead, recesses 17a, 17b and / or cutouts 17a, 17b and / or slots 17 allow flow. However, these recesses 17a, 17b and / or cutouts 17a, 17b and / or slots 17 do not provide flow along the entire periphery of the flow control adapter 14e. As a result, the flow values through the flow control adapter 14e tend to be smaller than the flow values through the flow control adapters 14a, 14b. Comparisons of flow coefficients between these embodiments apply at a constant pressure drop and for a constant inner diameter of the flow control adapter 14e.

[0113] The flow control adapter 14e advantageously forms a separate part from the frame 13 and from the gasket 12. The flow control adapter 14e may even be mechanically separable from both the frame 13 and the gasket 12. Separation is preferably non-destructive. That is, various flow control adapters 14a-14e can be used with the same frame 13 and the same gasket 12. More specifically, various flow control adapters 14a-14e can be attached and / or fitted to the same frame 13. For example, the various flow control adapters 14a-14e can be threaded and / or glued and / or shrink-fitted to the frame 13. When various flow control adapters 14a-14e can be attached to the same frame 13, the valve 1 can be more easily constructed. By exchanging the flow control adapter 14e, a large amount of flow rate through the valve can be achieved.
