Patent ID: 7921872

Claim:
A regulator device configured to reduce the gas pressure of a source of pressurized breathable gas in a self contained underwater breathing apparatus, comprising: a regulator housing; a gas inlet opening located within a bore in the regulator housing; a gas valve, comprising: a housing possessing an inlet opening and an exit opening; a passageway extending downstream of the inlet opening; a filter located within the passageway and proximate the exit opening and distal the inlet opening so that fluid must pass through the filter to pass through the exit opening; and a retainer device for removably securing the filter within the exit opening of the passageway; and a moveable cover member adapted to cover the inlet opening of the gas valve, the moveable cover member having a range of motion between a first position wherein the moveable cover member covers the inlet opening and a second position outside of the passageway wherein the moveable cover member is displaced from the inlet opening, the moveable cover member being biased towards the first position; wherein the housing of the gas valve includes a portion threaded into the bore of the regulator housing; wherein the exit opening of the gas valve is in fluid communication with the gas inlet opening of the regulator housing; wherein the moveable cover member is adapted to move from the first position to the second position when the valve is attached to a source of compressed gas; and wherein the moveable cover member is adapted to automatically move from the second position to the first position when the valve is disconnected from a source of compressed gas.
