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. |
