ABSTRACT:
A suspension system effects attitude control of a vehicle by supplying and discharging a pressure fluid to and from a suspension unit disposed between the body of the vehicle and a wheel. The suspension system employs a variable displacement pump to constitute a pressure source for supplying a pressure fluid to the suspension unit and controls the pump by a control mechanism such that the discharge of the pump is maintained at a substantially constant level, thereby enabling the load applied to the engine of the vehicle to be maintained at a substantially constant level, and thus achievinhg an increase in output of the engine.
