ABSTRACT:
An accumulator device comprising a pressure vessel having a replaceable bladder assembly adapted to be inserted into position within the vessel through a bore defining the gas charging port. The device is characterized by the provision of a bladder assembly having a stem molded thereto and adapted to project through the bore at the gas charging end of the vessel. A locking ring having larger diameter than the bore is rendered insertible endwise into the interior of the vessel as a result of the provision of reduced side portions. A retainer plate is provided which is insertible over the stem from the exterior of the vessel, the retaining plate including aligned portions projecting downwardly into the bore and filling the space between the reduced side or clearance portions of the ring and the bore to prevent extrusion of the bladder through the bore.
