Abstract:
1. A vehicle suspension system comprising: a housing defining an interior chamber containing an incompressible fluid and a hollow rod supporting a piston with the rod and the piston extending into the interior chamber, the housing being movable relative to the hollow rod such that fluid volume in the interior chamber varies; a multi-chambered manifold operatively connected to the hollow rod and having a first gas chamber and a second gas chamber; a first plunger, a second plunger, and a third plunger supported by the manifold; wherein the first plunger extends into the first gas chamber and is in fluid communication with the interior chamber via the hollow rod so that the first plunger moves relative to the first gas chamber in response to movement of the housing relative to the hollow rod; wherein the second plunger extends into the second gas chamber and is in fluid communication with the interior chamber via the hollow rod; wherein the third plunger extends into the first gas chamber; a first actuator operable to move the third plunger to vary a volume of the first gas chamber between the first and third plungers; and a second actuator operable to move the second plunger to vary a volume of the second gas chamber in fluid communication with the first gas chamber and simultaneously vary fluid volume in the interior chamber to thereby move the housing relative to the hollow rod.
