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.

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 hydroformed bellows.

Abstract: A reduced weight and repairable piston accumulator. The accumulator includes a load bearing metallic cylinder with removable end caps secured thereto with slip flanges for allowing repairability and for achieving the required cycle life. The cylinder serves as the surface on which the piston slides and is designed such that it sustains the axial stress induced by pressurization of the accumulator. A composite over wrapping is designed such that it sustains the stress in the hoop (radial) direction. A stress transitioning bushing can be provided for transitioning hoop stresses between the overwrap and the slip flange. When combined with the cylinder, the fibers of the composite wrap will not be placed in shear and thus will not fatigue in the same manner as some prior art designs.

Abstract: Apparatus for attaching internal parts to the interior of a pressure vessel having an inner lining of uncured rubber includes a rigid fastener, preferably an internally threaded nut, rigidly secured over an opening through the wall of the vessel and the rubber lining. A rigid bolt is threaded through the nut from the inside of the vessel so that a lateral shoulder on the bolt is tightened against the rubber lining. A layer of uncured rubber is mounted over the shoulder, and the layer is cured when the inner lining is being cured to embed the shoulder in the rubber and seal the bolt against leakage. Internal parts are attached to the portion of the bolt inside the vessel, and the structural load applied to the bolt by the internal parts is transmitted to the wall of the vessel through the rigid bolt and nut.

Abstract: An annular tube (or other shape) of elastomeric cellular material comprising elastomeric closed cells having gas infused therein is supported by structures protruding from the bottom surface of a suction stabilizer's head and/or by structures within the interior volume of the annular body of the suction stabilizer, preferably with spacing between the outer diameter of the annular tube of the cellular material and the inner walls of the suction stabilizer body. The gas-infused closed cell material may thus be employed in new suction stabilizer or pulsation dampener or to retrofit existing suction stabilizers or pulsation dampeners designed for a gas-filled bladder.
