Claims10
An accumulator of a hydraulic active suspension system, comprising:
- a first liquid-filled volume in fluid communication with a compression volume or an extension volume of a hydraulic actuator of the active suspension system;
- a flow path through which liquid may be exchanged between the first liquid-filled volume and the compression volume or the extension volume of the hydraulic actuator;
- a first gas-filled chamber;
- a moveable barrier separating the first liquid-filled volume from the first gas-filled chamber;
- a second gas-filled chamber;
- and
- a first gas flow path that connects the first gas-filled chamber to the second gas-filled chamber.
