Abstract
A vehicle suspension wherein hydraulic fluid is delivered to or from each spension unit via a pilot-operated shuttle valve. Each shuttle valve is controlled by the pressure within the suspension unit, such that suspension force is maintained during jounce and rebound motions. The various shuttle valves may be located in a common manifold housing to reduce the plumbing complexity. The shuttle valves may be selectively bypassed under special circumstances, e.g., to lower the vehicle, or to facilitate vehicle turning maneuvers.
