Abstract

A hydraulic accumulator includes a housing with a pair of ends, a piston slidably disposed in the interior of the housing, and a biasing member that urges the piston towards one end of the housing. The accumulator further includes a fluid flow control device in communication with a fluid chamber defined by a face of the piston and the interior surface of the housing. The desired amount of fluid entering and exiting the fluid chamber is controlled by the fluid flow control device according to the desired pressure within the fluid chamber as determined by a pressure sensor which is also in communication with the fluid chamber.
