Abstract

A hydraulic accumulator comprising a bladder to be filled with gas mounted in a pressure vessel, has a pair of concentric cylinders arranged at the bottom of the vessel coaxial with the bladder, said cylinders being connected to a liquid inlet port and a liquid outlet port respectively. Pressure liquid supplied to the inlet port is delivered to the center of the bottom of the bladder and then around the whole area of the bladder thus avoiding asymmetric distortion of the bladder by pressure pulses. <IMAGE>
