Abstract

Cryogenic solenoid valves are disclosed. A solenoid valve assembly includes a valve body that includes a valve seat. The solenoid valve assembly includes a cartridge mounted to the valve body, a plunger slidably received by the cartridge, and a seat disc holder slidably received by the cartridge. The solenoid valve assembly includes a retainer attached to the seat disc holder such that the retainer and the seat disc holder form a plunger head receiving cavity that houses a head of the plunger. The solenoid valve assembly includes a seat disc attached to the seat disc holder. The solenoid valve assembly includes an electromagnetic coil energizable to cause the solenoid valve assembly to move from a closed configuration in which the seat disc sealingly engages the valve seat and an open configuration in which the seat disc is disengaged from the valve seat.

First claim

What is claimed is:

1. A solenoid valve assembly, comprising:
a valve body comprising a valve seat and defining an inlet and an outlet in fluid communication with one another;
a cartridge mounted to the valve body;
a plunger slidably received by and configured to abut the cartridge;
a seat disc holder slidably received by the cartridge;
a retainer attached to the seat disc holder such that the retainer and the seat disc holder form a plunger head receiving cavity that houses a head of the plunger;
a seat disc attached to the seat disc holder; and
an electromagnetic coil energizable to cause the solenoid valve assembly to move from a closed configuration in which the seat disc sealingly engages the valve seat and prevents fluid flow from the inlet to the outlet to an open configuration in which the seat disc is disengaged from the valve seat and enables fluid flow from the inlet to the outlet.

2. The solenoid valve assembly of claim 1 , wherein the electromagnetic coil is energizable to cause the solenoid valve assembly to move from the closed configuration to a first intermediate configuration, from the first intermediate configuration to a second intermediate configuration, and from the second intermediate configuration to the open configuration.

3. The solenoid valve assembly of claim 2 , wherein the plunger is in:
a first plunger position when the solenoid valve assembly is in the closed configuration;
a second plunger position different from the first plunger position when the solenoid valve assembly is in the first intermediate configuration; and
a third plunger position different from the first and second plunger positions when the solenoid valve assembly is in the second intermediate configuration and when the solenoid valve assembly is in the open configuration.

4. The solenoid valve assembly of claim 2 , wherein the seat disc holder is in:
a first seat disc holder position when the solenoid valve assembly is in the closed configuration and when the solenoid valve assembly is in the first intermediate configuration;
a second seat disc holder position different from the first seat disc holder position when the solenoid valve assembly is in the second intermediate configuration; and
a third seat disc holder position different from the second seat disc holder position when the solenoid valve assembly is in the open configuration.

5. The solenoid valve assembly of claim 2 , wherein the retainer is in:
a first retainer position when the solenoid valve assembly is in the closed configuration and when the solenoid valve assembly is in the first intermediate configuration;
a second retainer position different from the first retainer position when the solenoid valve assembly is in the second intermediate configuration; and
a third retainer position different from the second retainer position when the solenoid valve assembly is in the open configuration.

6. The solenoid valve assembly of claim 2 , wherein the seat disc is in:
a first seat disc position when the solenoid valve assembly is in the closed configuration and when the solenoid valve assembly is in the first intermediate configuration;
a second seat disc position different from the first seat disc position when the solenoid valve assembly is in the second intermediate configuration; and
a third seat disc position different from the second seat disc position when the solenoid valve assembly is in the open configuration.

7. The solenoid valve assembly of claim 2 , wherein the seat disc sealingly engages the valve seat when the solenoid valve assembly is in the closed configuration and when the solenoid valve assembly is in the first intermediate configuration.

8. The solenoid valve assembly of claim 1 , further comprising a biasing member that biases the solenoid valve assembly to the closed configuration, wherein the biasing member extends between the cartridge and the plunger.

9. A solenoid valve assembly, comprising:
a valve body comprising a valve seat and defining a flow passage;
a cartridge mounted to and extending from the valve body, wherein the cartridge defines a cartridge cavity;
a plunger slidably received by and configured to abut the cartridge, wherein the plunger comprises a plunger stem and plunger head, and wherein the plunger head is slidably received in the cartridge cavity;
a seat disc holder slidably received by the cartridge, wherein the seat disc holder includes a plunger-contact surface and a seat-disc-engaging surface;
a retainer fixedly attached to the seat disc holder to form a plunger-head cavity in which the plunger head is enclosed, wherein the retainer defines a bore through which the plunger stem slidably extends, wherein the plunger head is configured to engage the plunger-contact surface of the seat disc holder in a closed configuration of the solenoid valve assembly;
a seat disc attached to the seat disc holder along the seat-disc-engaging surface;
a spring extending between the cartridge and the plunger, wherein the spring is configured to push the seat disc, via the seat disc holder, toward the valve seat to bias the solenoid valve assembly toward the closed configuration at which the seat disc sealingly engages the valve seat to prevent fluid to flow through the flow passage; and
an electromagnetic coil configured to draw the plunger toward an open configuration of the solenoid valve assembly when energized, wherein, in the open configuration, the seat disc is pulled away from the valve seat, via the seat disc holder, to enable the fluid to flow through the flow passage.

10. The solenoid valve assembly of claim 9 , wherein the electromagnetic coil is configured to transition the solenoid valve assembly from the closed configuration to a first intermediate configuration by drawing the plunger to disengage from the plunger-contact surface of the seat disc holder and engage the retainer.

11. The solenoid valve assembly of claim 10 , wherein, as the solenoid valve assembly is to transition from the closed configuration to the first intermediate configuration, the plunger is configured to slide relative to the cartridge, the seat disc holder, the retainer, and the seat disc.

12. The solenoid valve assembly of claim 10 , wherein the electromagnetic coil is configured to transition the solenoid valve assembly from the first intermediate configuration to a second intermediate configuration by further drawing the plunger to cause the plunger head to pull the retainer, the seat disc holder, and the seat disc and, in turn, cause the seat disc to disengage from the valve seat to permit the fluid to begin to flow through the flow passage.

13. The solenoid valve assembly of claim 12 , wherein, as the solenoid valve assembly is to transition from the first intermediate configuration to the second intermediate configuration, the plunger, the retainer, the seat disc holder, and the seat disc are configured to slide relative to the cartridge.

14. The solenoid valve assembly of claim 12 , wherein the fluid flowing through the flow passage is configured to cause the solenoid valve assembly to transition from the second intermediate configuration to the open configuration by causing the seat disc to slide further away from the valve seat.

15. The solenoid valve assembly of claim 14 , wherein, as the solenoid valve assembly is to transition from the second intermediate configuration to the open configuration, the seat disc holder, the retainer, and the seat disc are configured to slide relative to the cartridge and the plunger.

16. A solenoid valve assembly, comprising:
a valve body comprising a v
