Abstract: A fill valve (200) adapted for use with a pressurized fluid container includes a fill port (112) configured to be in fluidic communication with the pressurized fluid container and a fill valve member (201) configured for selectively blocking the fill port (112) and configured to be non-openable after the fill valve member (201) has been moved to a blocking position that substantially closes the fill port (112). The fill valve member (201) includes a valve member body (210) and a break-away head (220) joined to the valve member body (210) by a breakable neck (228). The breakable neck (228) is configured to break when the fill valve member (201) is moved to a substantially fully closed position in the fill port (112).

Abstract: An outlet valve (700) adapted for use with a pressurized fluid container includes an outlet valve chamber (701) including an upper groove (722) and a lower groove (725), an outlet valve member (760) configured to move between substantially open and substantially closed positions in the outlet valve chamber (701), and a non-return member (780) configured to be retained in one of the upper groove (722) or the lower groove (725) in a snap-fit arrangement. When the non-return member (780) is retained in the upper groove (722) the non-return member (780) does not contact the outlet valve member (760). When the non-return member (780) is retained in the lower groove (725) the non-return member (780) blocks the outlet valve member (760) in the substantially open position.

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).

When the non-return member (780) is retained in the upper groove (722) the non-return member (780) does not contact the outlet valve member (760). When the non-return member (780) is retained in the lower groove (725) the non-return member (780) blocks the outlet valve member (760) in the substantially open position.

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).
