Abstract
A compressor valve assembly is presented. The compressor valve assembly includes a seat and a guard attached to each other. The seat includes an inlet hole. The guard includes a spring. The guard includes a guide pin attached to the bottom of the guard and extends out the spring internally. The guard includes a seal element attached to the guide pin. The seal element includes a socket to receive the guide pin and a spring landing area residing on top of the spring. The guide pin internally guides a movement of the seal element to move toward the inlet hole when the spring extends and to move away from the inlet hole when the spring is compressed.
Claims19
A compressor valve assembly comprising:
- a seat comprising an inlet hole;
- and
- a guard attached to the seat,
- wherein the guard comprises:
- a spring;
- a guide pin attached to the bottom of the guard and extending out the spring internally;
- and
- a seal element attached to the guide pin,
- wherein the seal element comprises a socket defining an opening to receive the guide pin,
- wherein the seal element comprises a seal head disposed on one end of the socket,
- wherein the seal element comprises a spring landing area residing on top of the spring, and
- wherein the guide pin is configured to guide a movement of the seal element along the guide pin such that the seal head of the seal element moves toward the inlet hole when the spring extends and moves away from the inlet hole when the spring is compressed during an operation of the compressor valve assembly.
A guard for a compressor valve assembly comprising:
- a spring;
- a guide pin attached to the bottom of the guard and extending out the spring internally;
- a seal element attached to the guide pin,
- wherein the seal element comprises a socket defining an opening to receive the guide pin,
- wherein the seal element comprises a seal head disposed on one end of the socket,
- wherein the seal element comprises a spring landing area residing on top of the spring, and
- wherein the guide pin is configured to guide a movement of the seal element along the guide pin such that the seal head of the seal element moves toward the inlet hole when the spring extends and moves away from the inlet hole when the spring is compressed during an operation of the compressor valve assembly.
A method for operating a compressor valve assembly, wherein the compressor valve assembly comprises a seat and a guard attached to each other, wherein the seat comprises an inlet hole, the method comprising:
- disposing a spring in the guard;
- attaching a guide pin to the bottom of the guard and extending out the spring internally;
- and
- attaching a seal element to the guide pin,
- wherein the seal element comprises a socket defining an opening to receive the guide pin,
- wherein the seal element comprises a seal head disposed on one end of the socket,
- wherein the seal element comprises a spring landing area residing on top of the spring, and
- wherein the guide pin is configured to guide a movement of the seal element along the guide pin such that the seal head of the seal element moves toward the inlet hole when the spring extends and moves away from the inlet hole when the spring is compressed during an operation of the compressor valve assembly.
