    Abstract: A pressure regulator (500) is provided. The pressure regulator (500) comprises a housing (503), a fluid inlet (508) to receive a pressurized fluid at an inlet pressure, and a fluid outlet (510) to output the pressurized fluid at a regulated pressure. The pressure regulator (500) further includes a regulating piston (504) movable within the housing (503) to provide fluid communication between the fluid inlet (508) and the fluid outlet (510). The regulating piston (504) includes a first end (505) comprising a first cross-sectional width (D,) in fluid communication with the fluid inlet (508) and a second end (509) comprising a second cross-sectional width (D2) in fluid communication with the fluid outlet (510). The first and second cross-sectional widths (D15 D2) are sized such that the regulated pressure at the fluid outlet (510) is correlated to the inlet pressure at the fluid inlet (508).

    Abstract: A relief valve (100) is provided, including a floating piston (120) configured to move reciprocally in a piston chamber (103) in response to fluid pressure, a circumferential seal (124) located on the floating piston (120), a biasing device (130) configured to keep the floating piston (120) within a piston float movement range, wherein the fluid is held when the floating piston (120) is within the piston float movement range and the fluid is exhausted when the floating piston (120) exceeds the piston float movement range, and one or more relief grooves (107) formed in a sidewall (106) of the piston chamber (103). The one or more relief grooves (107) are configured to conduct fluid around the floating piston (120) and the circumferential seal (124) when the floating piston (120) is compressed to a predetermined relief location in the piston chamber (103).
