Abstract
A pressure regulator has a main body, a piston, an elastic element and an adjusting element. The main body has an inlet and an outlet. The piston is mounted movably between the inlet and the outlet. The elastic element is mounted in the main body to prepossess that the piston to move toward the outlet of the main body. The adjusting element is mounted adjustably in the main body and selectively abuts against the piston to selectively close a flow path from the inlet to the outlet. Adjusting the position of the adjusting element results influences the compressed length of the elastic element. Therefore, the preset outlet pressure is fine-tuned.
Claims20
A pressure regulator comprising:
- a main body adapted for being mounted on a high pressure source without intermediary and having
- an inlet;
- an outlet;
- a high pressure chamber defined between the inlet and the outlet and communicating with the inlet;
- and
- a regulated chamber defined between the inlet and the outlet and communicating with the outlet and the high pressure chamber;
- a piston mounted moveably in the high pressure chamber and the regulated chamber and having
- a first end toward the inlet of the main body;
- a second end toward the outlet of the main body;
- a sealing segment attached to the first end of the piston;
- an elastic element mounted in the regulated chamber of the main body to prepossess the piston to move toward the outlet of the main body;
- and
- an adjusting element mounted adjustably in and selectively held in the high pressure chamber of the main body, and having a central opening formed axially through the adjusting element and communicating with the inlet to selectively allow a flow path from the inlet passing through the central opening of the adjusting element and the sealing segment to the outlet, wherein the adjusting element selectively abutting abuts against the sealing segment and the central opening of the adjusting element is selectively blocked by the sealing segment to selectively close the flow path from the inlet to the outlet of the main body.
A high pressure source assembly comprising:
- a high pressure source;
- and
- a pressure regulator connecting to the high pressure source and having a main body mounted on the high pressure source without intermediary and having
- an inlet connecting to the high pressure source;
- an outlet;
- a high pressure chamber defined between the inlet and the outlet and communicating with the inlet;
- and
- a regulated chamber defined between the inlet and the outlet and communicating with the outlet and the high pressure chamber;
- a piston mounted moveably in the high pressure chamber and the regulated chamber and having
- a first end toward the inlet of the main body;
- a second end toward the outlet of the main body;
- a sealing segment attached to the first end of the piston;
- an elastic element mounted in the regulated chamber of the main body to prepossess the piston to move toward the outlet of the main body;
- and
- an adjusting element mounted adjustably in and selectively held in the high pressure chamber of the main body, and having a central opening formed axially through the adjusting element and communicating with the inlet to selectively allow a flow path from the inlet passing through the central opening of the adjusting element and the sealing segment to the outlet, wherein the adjusting element selectively abuts against the sealing segment and the central opening of the adjusting element is selectively blocked by the sealing segment to selectively close a flow path from the inlet to the outlet of the main body.
