Abstract
A pressure regulator includes a regulator body, and a piston slidably disposed in the regulator body, wherein an end of the piston extends axially beyond an end of the regulator body and is exposed to an external pressure. A method of regulating pressure includes providing a pressure regulator having a piston slidably disposed in a regulator body, wherein an end of the piston extends beyond an end of the regulator body and is exposed to an external pressure, applying external pressure on the end of the piston, and outputting a regulated working fluid pressure from the pressure regulator.
