<p>This invention relates to the art of pressure vessels, more particularly of the type having a rigid container with a deformable bladder therein dividing the container into two variable volume chambers, each adapted to receive fluid under pressure. A port is in communication with one of said chambers and a valve member mounted axially on the bladder and molded integrally therewith is associated with said port to close the latter. The valve member is molded into the bladder in such manner that the force exerted by the compressed gas in the bladder will exert a minimum of shearing stress against the molded junction of the valve member to the associated end of the bladder to prevent shearing. In addition, the valve member has a portion extending axially behond the molded junction thereby eliminating impact against such molded junction when the valve member seats to close the port.</p> |
