    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: A lightweight, optimally efficient, easily serviced, piston-in-sleeve high pressure accumulator is provided. The accumulator includes one or more cylindrical composite pressure vessel separate end cap manifolds. A piston slidably disposed in a thin impermeable internal sleeve in the accumulator separates two chambers, one adapted for containing a working fluid and the other adapted for containing gas under pressure. Gas is provided in a volume between the impermeable internal sleeve and the composite pressure vessel wall. Additional gas is optionally provided in gas cylinders. Further components are provided for withstanding harmful effects of radial flexing of the composite vessel wall under high pressures, and from stresses present in use in mobile applications such as with a hydraulic power system for a hydraulic hybrid motor vehicle.

    Abstract: PROBLEM TO BE SOLVED: To provide a structure that is simple, and exerts no resistance to fluid flow at movement of a valve body, in a valve used for a reservoir tank of a hydraulic brake system for vehicle.SOLUTION: A reservoir chamber valve 1 of a hydraulic control type includes a closing member 13 that seals a valve seat 26 of a valve element 22, and is subjected to an initial stress via a first compression spring 14; and a tappet 12 that is coupled with a reservoir piston 10 urged by a second compression spring 15, and extrudes the closing member 13 from the valve seat 26, when an inherent power ratio is generated between a spring initial stress and a force acting in hydraulic manner. The first compression spring 14 and the closing member 13 are guided in a filter 24. The valve element 22 including the valve seat 26 and a filter 24 including a guide means are fabricated as an integrated plastic member 20.
