    摘要： The present invention provides lightweight high-pressure accumulators that avoids diaphragm failure observed in conventional diaphragm accumulators. Lightweight high-pressure composite overwrapped accumulators of the invention are made from a plurality of hollow casings that are mated to form an accumulator housing. The accumulator housing is overwrapped with a composite material to provide additional mechanical strength and structural integrity. More significantly, the accumulators of the invention includes a plurality of annular grooves and a plurality of bulb on the flexible diaphragm such that the plurality of bulbs on the flexible diaphragm are placed in the plurality of annular grooves that are formed between the first and the second hollow casing. In this manner, diaphragm failure is significantly reduced or even completely eliminated during repeated high pressure charge/discharge cycle of the accumulator.

    摘要： Provided is an accumulator that prevents foreign matters from entering a space S between a housing and a gas plug that is fitted to a concave portion of the housing. An accumulator (100) includes: a housing (110) having an injection opening (112b) into which pressure gas is injected; and a gas plug (150) occluding the injection opening (112b), and seals the pressure gas in the housing (110) by the gas plug (150) that is welded to the housing (110) with a welding portion (151) of the gas plug (150) being melted, wherein the housing (110) includes: a concave portion to which the gas plug (150) occluding the injection opening (112b) is fitted, and to which the gas plug (150) is welded with the welding portion (151) being melted on its bottom surface (110a); and an inclined surface (110c) that extends from an edge portion of the concave portion toward an outside of the housing (110) such that a distance from a center of the injection opening (112b) increases, and the gas plug (150) includes a flange (152) which makes contact with the inclined surface (110c) in a state of being fitted and welded to the concave portion.
