Abstract
A pressure regulator is provided. In one embodiment, the pressure regulator includes a housing having a supply port for receiving a pressurized medium within the housing and an outlet port for outputting the pressurized medium to a downstream device. The housing of this embodiment also includes a vent port for venting the pressurized medium from the housing. The pressure regulator of this embodiment further includes two pistons disposed within the housing, wherein one piston controls flow of the pressurized medium through the supply port, and the other piston controls flow of the pressurized medium through the vent port, based on the level of pressure within the housing. Other embodiments of pressure regulator devices and systems are also provided.
Claims13
A pressure regulator comprising:
- a housing comprising:
- a supply port that facilitates receipt of a pressurized medium within the housing;
- an outlet port that facilitates outputting the pressurized medium to a downstream device;
- and
- a vent port that facilitates venting the pressurized medium from the housing;
- a first piston disposed within the housing;
- a supply shear seal ring disposed within a recess of the first piston, wherein the first piston and the supply shear seal ring are configured to selectively control flow of the pressurized medium through the supply port based on a pressure within the housing;
- a second piston disposed within the housing, wherein a portion of the first or second piston is disposed within an opening of the other;
- and
- a vent shear seal ring disposed within a recess of the second piston, wherein the second piston and the vent shear seal ring are configured to selectively control flow of the pressurized medium through the vent port based on the pressure within the housing.
