Abstract
An active suspension system is provided with a pressure accumulator connected to a drain line connecting a drain port of a pressure control valve which controls pressure in the working chamber of an active cylinder. The pressure accumulator serves to absorb high pressure surge. A surge pressure absorbing unit is provided for feeding back the surge pressure generated in the drain line to the pressure accumulator via a supply line so that the surge pressure can be successfully absorbed by the pressure accumulator.
