Patent ID: 8075002

Claim:
A suspension system for a vehicle, said suspension system comprising: a hydraulic system including: a plurality of hydraulic actuators; a plurality of control valves associated with said hydraulic actuators; a hydraulic pump; a hydraulic accumulator; a reservoir; and a compressible hydraulic fluid in hydraulic communication with said plurality of hydraulic actuators, said plurality of control valves, said hydraulic pump, and said reservoir; and a controller adapted to process data received from one or more switches or sensors and provide control signals to said control valves according to an algorithm embodied in said controller; wherein said hydraulic actuators, said hydraulic pump, and said hydraulic accumulator operate at static hydraulic pressures of at least about 5750 psi; wherein said reservoir operates at a pressure lower than the operating pressure of said hydraulic actuators, said hydraulic pump, and said hydraulic accumulator; wherein said hydraulic actuators are selectively charged with hydraulic fluid drawn from said reservoir; and wherein said actuators selectively discharge said hydraulic fluid to said reservoir.
