    Abstract: A bladder (10) for an accumulator (20) has a hollow shell (21) formed of an elastic material layer (11), a gas-barrier layer (12) laminated thereon, and a central portion (11A). An elastic fitting portion is formed at an inner surface of a radially outward peripheral edge portion (11B) of the elastic material layer to be pressed radially outwardly towards the shell when the fitting portion (11A) is attached to the shell by an attaching element (22). The thickness of the bladder varies between the central and peripheral edge portions by being thinner proximate the central portion and thicker at a curved inversion portion (11C) between the intermediate portion and the outer peripheral edge portion to reduce rigidity at the intermediate portion and preventing lumping in the curved inversion portion.

    Abstract: The invention relates to a hydropneumatic accumulator in which a bladder or membrane supported within a vessel establishes a chamber for confining a compressible fluid within the vessel and also provides means for supporting a valve plate opposite inlet and outlet ports arranged so that as the valve plate position responds to pressure changes normal flow between the ports may be maintained and extruding of the bladder or diaphragm into the outlet port prevented.

    Abstract: A mushroom-shaped shield body, that is, a shield body having a configuration consisting of a back surface tapered section having its diameter successively increased towards the inside of an accumulator and a stem portion, is disposed coaxially at the inside end portion of a liquid feed/discharge port of the accumulator, and an inner surface tapered section is formed along the circumference of the liquid feed/discharge port opposed to the back surface tapered section of the shield body to form an annular liquid flow path between said back surface tapered section and said inner surface tapered section so that the direction of the liquid flow passing through this annular flow path may be directed along the inner wall surface of the vessel of the accumulator, whereby a diaphragm disposed within the accumulator can be deformed so as to conform to the inner wall surface of the vessel and thus the volume efficiency of the accumulator can be enhanced.

    Abstract: An inexpensive pressure vessel which can be disposed of rather than being repaired once it fails, which includes a cylindrical housing having two chambers separated by a resilient bladder. One chamber is for housing a gas while the second is for housing a fluid such as hydraulic oil. The cylindrical housing contains a port at one end and is open at the opposite end. The end cap which contains a through port and a gas valve is insertable into the open end of the cylindrical housing and is welded thereto. This weld joint in conjunction with a seal formed by attaching the resilient bladder to the end cap, will positively seal the pressure vessel. The unique seal between the end cap, bladder and housing is such that it will not be thermally damaged by the welding process which seals the end cap to the cylindrical housing.
