PRESSURE ASSISTED ELECTROMAGNETIC FLOW CONTROL VALVE FOR LIQUID AND GAS APPLICATIONSCross-Reference to Related Application:

[0001] The present application claims the benefit of the filing date of Indian Provisional Application No. 202441045692 filed on June 13, 2024, which is incorporated herein by reference.TECHINICAL FIELD

[0002] The present application relates generally to an electromagnetic flow control valve having a pressure assisted seal.BACKGROUND

[0003] An electromagnetic actuator operates an electromagnetic flow control valve by converting electrical energy into magnetic force. The electromagnetic actuator includes a solenoid such as a coil winding that creates an electromagnetic field wherein current flows through it. Typically, a frame or shell surrounds the solenoid coil and concentrates the magnetic field. A guide tube is assembled within the solenoid and frame such that the guide tube forms a guide for a plunger and receives the plunger therein. When an electrical current is applied to the coil winding, it generates a magnetic field. The magnetic force attracts or repels a movable component within the flow control valve. This movement controls the direction of flow by opening or closing the passageway for fluid.

[0004] Electromagnetic flow control valves used in liquid and / or gas applications often need to operate at higher working pressures such as around 20 bar or higher. These types of electromagnetic flow control valves are expected to meet stringent sealing requirements in a closed condition. In a closed condition, to seal and operate against high pressure, in some embodiments a larger sized solenoid for the electromagnetic actuator is used. A larger sealing area can meet flow rate requirements and that larger sealing area has a corresponding larger current for operation. Heat can be generated due to the higher current and higher resistance so heat management is a consideration. In other embodiments, a very strong spring can be used to maintain the electromagnetic flow control valve in a closed position.SUMMARY

[0005] A flow control valve for assembly with an actuator. The flow control valve includes a valve body having one or more inlets to receive pressure and a passageway having a length that spans between a first opening and a second opening. A sealing member is assembled with the passageway and the sealing member includes an outlet to receive pressure there through. The sealing member includes a plunger opening for a plunger that assembles with a movable component of the actuator such that the plunger is movable between an open position and a closed position. A biasing member is assembled with the sealing member and the movable component of the actuator. In a closed position of the flow control valve such that no pressure exits the outlet, the biasing member biases the plunger against the sealing member and pressure through the one or more inlets pushes against the movable component to further move the plunger against the sealing member to seal the plunger opening in the sealing member.

[0006] The one or more inlets apply pressure against the plunger and the passageway of the valve body which results in a first fluid force applied to the movable component and a second fluid force applied to the plunger. As such, the first fluid force operates to push the movable component away from the sealing member. The second fluid force operates to push the plunger away from the sealing member and towards the outlet. The first fluid force is greater than the second fluid force since a cross-sectional area of the passageway is larger than a cross-sectional area of the plunger opening to thereby form a net fluid force that acts against movable component. As such, the net fluid force pushes against the movable component to further move the plunger against the sealing member to seal the plunger opening and the outlet which results in a closed condition of the flow control valve.

[0007] As a result of the net fluid force pushing against the movable component to further move the plunger against the sealing member to seal the plunger opening and the outlet, a smaller biasing force for the biasing member is required to maintain the plunger in the closed position. A smaller biasing member requires a smaller magnetic portion for the electromagnetic actuator to overcome the bias force of the biasing member to thereby move the movable component and the plunger away from the sealing member to unseal the plunger opening and allow pressure to escape through the outlet. Additionally the valve body can be smaller and / or compact in size. A smaller valve body results in a smaller plunger which reduces the overall size of the flow control valve.

[0008] As the pressure increases from the one or more inlets then the sealing of the plunger opening improves or increases as the net force applied to the movable component increases thereby causing the plunger to move against the sealing member and the plunger opening. In hydrogen and natural gas applications or other applications that require higher pressures it is very undesirable for any unintended gas to go downstream or leak.

[0009] The flow control valve disclosed herein reduces parasitic losses (current drawn from control unit) and reduces heat generation. The flow control valve is easily packaged since the flow control valve has an overall compact size which also reduces the overall cost. A smaller solenoid or magnetic portion is required to move the movable component.

[0013] FIG. 2 illustrates a partial cross-sectional view of the flow control valve of FIG. 1.DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

[0014] For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended, any alterations and further modifications in the illustrated embodiments, and any further applications of the principles of the invention as illustrated therein as would normally occur to one skilled in the art to which the invention relates are contemplated herein.

[0015] FIG. 1 illustrates one embodiment of a flow control valve 20 assembled with an electromagnetic actuator 22. FIG. 2 illustrates a partial view of the flow control valve 20 from FIG. 1 that includes a valve body 30, a sealing member 32, a plunger 34, and a biasing member 36. Each of these components of the flow control valve 20 are described below.

[0016] The flow control valve 20 is assembled with the electromagnetic actuator 22. The electromagnetic actuator 22 includes a magnetic portion 24 with a frame 26 that surrounds the magnetic portion 24 and concentrates the magnetic field. The electromagnetic actuator 22 includes a movable component 80 that is assembled within the magnetic portion 24 and frame 26. The movable component 80 receives the plunger 34 from the flow control valve 20 therein. The magnetic portion 24 includes one or more of a wound coil, a bobbin, an armature, a pole piece, a pole piece washer, a case or a flux piece.

[0017] The valve body 30 has an annular wall 40 that defines a first inlet 42 and a second inlet 44 that are each configured to receive pressure there through. In other embodiments, the annular wall 40 may include only one of the first or second inlets 42 and / or 44. In yet other embodiments, the annular wall 40 can include additional inlets. The annular wall 40 is further configured to define a passageway 46 that includes a length that spans between a first opening 50 and a second opening 52. The passageway 46 includes an inner diameter that can vary along the length between the first and second openings 50 and 52. In the illustrated embodiment, the passageway 46 includes a first diameter DI that corresponds to the first opening 50 wherein the passageway 46 having the first diameter DI spans along a partial length LI of the passageway 46 to a ledge 54 sized to receive a plunger guide 56. The passageway 46 includes a second diameter D2 that is smaller or less than the first diameter DI . The passageway 46 having the second diameter D2 extends along a partial length L2 of the passageway 46 to athird diameter D3 that is larger than the second diameter D2. The passageway 46 having the third diameter D3 extends along a partial length L3 of the passageway 46 to the second opening 52. In other embodiments, the passageway 46 is configured differently. The second opening 52 is sized to receive the sealing member 32 therein. The annular wall 40 includes an exterior surface 60 that includes one or more grooves 62a-62c sized to receive a sealing ring 64 therein. In other example embodiments, the exterior surface 60 may not include the one or more grooves 62a-62c.

[0018] The sealing member 32 is assembled with the passageway 46 such that the sealing member 32 is positioned in the second opening 52. In one embodiment, the sealing member 32 is assembled within the passageway 46 to form a press-fit joint. In other embodiments, the sealing member 32 may be assembled in the passageway 46 to form another type of joint such as a snap-fit joint. Yet, in other embodiments, the sealing member 32 and the passageway 46 are configured to threadingly engage with each other.

[0019] In FIG. 2, the sealing member 32 includes a sealing member body 70 having a sealing wall 72 that extends to a sealing ceiling 76. The sealing wall 72 defines an outlet 74 configured to receive pressure there through to exit the flow control valve 20. The sealing ceiling 76 includes a plunger opening 78 sized to receive the plunger 34 and pressure there through when the plunger 34 is in the open condition or position. As such, pressure is received through the plunger opening 78 when the plunger 34 is in the open position. In other embodiments, the sealing member 32 is not present and instead the passageway 46 of the valve body 30 is configured to receive the plunger 34 and form an outlet similar to outlet 74.

[0020] The plunger 34 is assembled in the plunger opening 78 of the sealing member 32 and the passageway 46 of the valve body 30. The plunger 34 is further configured to assemble with a movable component 80 of the actuator 22 such that the plunger 34 and the movable component 80 are movable between an open position and a closed position. The plunger 34 includes a shaft portion 90 that extends to a head portion 92 wherein the head portion 92 has a larger diameter than the shaft portion 90. In the illustrated embodiment, the movable component 80 includes a shaft portion 82 that extends to a head portion 84. The head portion 84 includes an opening 86 sized and configured to receive the shaft portion 90 of the plunger 34 therein. In one embodiment, the plunger 34 may be assembled with the movable component 80 to form a press- fit joint. In other embodiments, the plunger 34 is assembled with the movable component 80 toform another type of joint such as a snap-fit joint. In other embodiments, the plunger 34 and the movable component 80 may be configured to threadingly engage with each other. The head portion 92 has a width that is large enough to engage the sealing ceiling 76 of the sealing member 32 and cover the plunger opening 78 to thereby seal the plunger opening 78 when the plunger 34 is in the closed position.

[0021] The biasing member 36 is assembled with the sealing member 32. The biasing member 36 is further configured to assemble with the movable component 80 of the actuator 22. The biasing member 36 in the illustrated embodiment is a compression spring and is coaxial to the shaft portion 90 and head portion 84. The biasing member 36 provides a bias force that will seat the plunger 34 on the sealing ceiling 76 to cover the plunger opening 78 and block the flow between the first and second inlets 42 and 44 and the outlet 74. In some embodiments, a seal 100 is positioned between the head portion 92 of the plunger 34 and the sealing ceiling 76 of the sealing member 32. The biasing member 36 can be small to seat the plunger 34 on the sealing ceiling 76 to cover the plunger opening 78.

[0022] In the closed position for the flow control valve 20, the biasing member 36 is configured to bias the plunger 34 against the sealing ceiling 76 of the sealing member 32. The biasing member 36 provides force or load to seal the plunger 34 against the sealing member 32 or valve seat. The plunger 34 is assembled with the movable component 80 such that the biasing member 36 applies the force to the movable component 80 to pull the plunger 34 against the sealing ceiling 76 of the sealing member 32 to seal the plunger opening 78 and thereby also seal the outlet 74. The one or more inlets 42 and / or 44 apply pressure against the shaft portion 90 of the plunger 34 and the passageway 46 of the valve body 30 which results in a first fluid force applied to the movable component 80 and a second fluid force applied to the head portion 92 of the plunger 34. As such, the first fluid force operates to push the movable component 80 away from the sealing member 32. The second fluid force operates to push the head portion 92 and the plunger 34 away from the sealing member 32 and towards the outlet 74. The first fluid force is greater than the second fluid force since a cross-sectional area of the passageway 46 is larger than a cross-sectional area of the plunger opening 78 to thereby form a net fluid force that acts against movable component 80. As such, the net fluid force pushes against the movable component 80 to further move the plunger 34 against the sealing ceiling 76 to seal the plungeropening 78 and the outlet 74 which results in a closed condition wherein the head portion 92 of the plunger 34 is sealed against the plunger opening 78 and the sealing ceiling 76.

[0023] As a result of the net fluid force pushing against the movable component 80 to further move the plunger 34 against the sealing ceiling 76 to seal the plunger opening 78 and the outlet 74, a smaller biasing force for the biasing member 36 is required to maintain the plunger 34 in the closed position. A smaller biasing member 36 requires a smaller magnetic portion 24 for the electromagnetic actuator 22 to overcome the bias force of the biasing member 36 to thereby move the movable component 80 and the plunger 34 away from the sealing ceiling 76 to unseal the plunger opening 78 and allow pressure to escape through the outlet 74. Additionally the annular wall 40 can be smaller and / or compact in size. A smaller annular wall 40 for the valve body 30 results in a smaller plunger 34 which reduces the overall size of the flow control valve 20.

[0024] The flow control valve 20 can be used for air and other gas applications as well. In one embodiment, the flow control valve 20 is used in a hydrogen fuel cell application. Moreover, as the pressure increases from the one or more inlets 42 and / or 44 the sealing of the plunger opening 78 improves or increases as the net force applied to the movable component 80 increases thereby causing the plunger 34 to move against the sealing ceiling 76 and the plunger opening 78. In hydrogen and natural gas applications or other applications that require higher pressures it is very undesirable for any unintended gas to go downstream or leak.

[0025] The flow control valve 20 disclosed herein reduces parasitic losses (current drawn from control unit) and reduces heat generation. The flow control valve 20 is easily packaged since the flow control valve 20 has an overall compact size which also reduces the overall cost. A smaller solenoid or magnetic portion 24 is required to move the movable component. The smaller solenoid or magnetic portion 24 can be used to seal and operate against high pressure which is beneficial to reduce heat generation.
