ABSTRACT:
This invention relates to a pressure vessel for gas and oil under pressure comprising a container of rigid material having a cylindrical body portion defining a mouth at one end and closed at its other end, said closed end having an axial port. An annular supporting member of resilient sheet metal has a cylindrical upper portion of diameter just slightly less than that of the mouth portion of the container so that it may readily fit therein. An annular lower portion depends from said upper portion and the rim of a bladder is bonded to said lower portion, with a portion of the bladder material on the outer surface of said annular lower portion abutting and being compressed against the inner wall surface of the container to define an oil seal. A cylindrical closure plug or cover having an annular groove in the side wall thereof is positioned in the cylindrical upper portion of said supporting member with the inner periphery of the side wall of the plug abutting against and compressing the portion of the bladder material on the inner surface of the annular lower portion of the supporting member to define a gas seal.
