Claims (3)

1. CLAIMS 1. A pressure vessel comprising a container of rigid material having two ports, one of said ports being axially aligned with said container and defining a liquid port, a deformable bladder secured in said container and separating said two ports from each other to define two variable volume fluid receiving chambers, one of said chambers being in communication with said liquid port,; said bladder extending axially i said container and being closed at one end, means to charg said bladder with gas under pressure through the other of said ports, the portion of the container adjacent the periphery of the liquid port defining a valve seat, a valve member molded in th closed end of said bladder and axially aligned therewith adapted to move against said valve seat to close said liquid port, said valve member comprising a disc having an abutment surface adapted to engage said valve seat and having a reduced diameter portion extending axially outward therefrom defining a laterall extending annular flange of greater diameter than the abutment surface of said disc, said reduced diameter portion having a side wall to which the bladder material is bonded, said flange being interposed between the interior of said bladde and the bonded junction of th bladder material to said side wall.
2. The combination set forth in Claim 1 in which the periphery of said flange is rounded. \
3. The combination set forth in Claim 1 iri which a layer of bladder material extends over the surface of said disc arid around the periphery and undersurface of said flange and said bladder material is bonded to the' surface of said disc and to the periphery and undersurface of said flange. \ \ 42477/2 42477/2 7. Th® combination set forth in Claim 6 in which a groove is provided in said abutment surface extending inwardly from the Outer periphery thereof. 8. The combination set forth in Claim 6 i which a layer of bladder material extends over the surface of said disc and around the periphery and undersurface of said flange and said bladder material is bonded to the surface of said disc and to the periphery and undersurface of said flange.
