ULTRA LIGHTWEIGHT AND COMPACT ACCUMULATOR

摘要

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.
