ABSTRACT:
The present invention is directed to a pressure accumulator of the type which includes a rigid container or casing having substantially axially aligned ports in the ends thereof, and having a deformable open mouth bladder therein dividing the casing into a liquid chamber and a gas chamber in communication respectively with said ports, the port in communication with the gas chamber having a rigid fitting associated therewith, with a gas charging passageway extending therethrough and leading into the gas chamber, deformable closure member being associated with said fitting, automatically to seal the end of the passageway leading into the gas chamber upon discharge of gas from said gas chamber, to preclude extrusion of said bladder into said end of the passageway in said rigid fitting with consequent failure of the accumulator.
