  • Working fluid circuit for active suspension system with surge suppression during fail-safe mode operation
    Patent number: 5156645
    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.
