Abstract
A method for varying the damping force of a hydraulic damper in a vehicular suspension system includes rotatably fixing a reciprocable piston slidably mounted in a fluid-filled cylinder to the vehicular body and rotatably fixing the cylinder to a steerable wheel assembly. A variable flow fluid bypass is provided between upper and lower chambers of the cylinder. As the wheel assembly is steered, the bypass is opened and closed to vary fluid flow between the chambers and thus vary the damping force of the damper.
