Abstract

A high pressure accumulator for supplying working fluid of a hydraulic control system includes a cylinder, walls disposed on ends of the cylinder, a piston movable within the cylinder defining a space for the working fluid on one side of the piston and a space for gas forming a gas spring on the other side of the piston, a support tube disposed at one of the walls in the gas space, a spring disposed on the support tube, and a stop disposed on the spring for limiting movement of the piston upon the occurrence of a gas loss in the gas space.
