    Abstract: An accumulator for a hydraulic system includes a polymer liner defining a cavity. A metal bellows assembly is housed in the cavity and separates the cavity into a first chamber and a second chamber, with the first and second chambers isolated from one another by the bellows assembly. A composite shell substantially encases the liner. The liner and shell are configured so that the first chamber receives hydraulic fluid from and delivers hydraulic fluid through an opening in the liner and the shell as the bellows assembly expands and compresses due to pressurized gas in the second chamber balancing fluid pressure changes in the first chamber. In one embodiment, the metal bellows assembly includes hydro formed bellows.

    Abstract: An accumulator (ACC) in which a container main body (1) and a closure member (5) are screw-joined together. A reverse-buttress internal thread or an internal thread having an included angle of 90 degrees is used as an internal thread of the screw-joined portion. The reverse-buttress internal thread is formed in such a way that the inclination angle (beta) of a clearance flank of the buttress internal thread is the inclination angle (beta) of a reverse pressure flank (20A) receiving a load, and the inclination angle (theta) of a pressure flank is the inclination angle (theta) of a reverse clearance flank (2B). The internal thread having an included angle of 90 degrees is formed in such a way that inclination angles (alpha), (gamma) of both flanks are equal and the included angle (delta) is about 90 degrees.

    Abstract: An accumulator assembly comprises an accumulator cylinder formed of a cylindrical, gas-impermeable shell and a cylindrical gas-impermeable sleeve disposed within and substantially concentric with the shell. An interstitial space is formed between the sleeve and the shell. A piston slidably is disposed within the sleeve, the piston separating an interior of the sleeve into a first chamber configured to contain a compressed gas, and a second chamber configured to contain a pressurized fluid. A pair of removable axial closures retained to the gas-impermeable sleeve at opposing ends and sealingly engaged with corresponding opposing ends of the gas-impermeable shell is configured to provide maximum resistance to the tensional stress of the sleeve.
