    摘要: A variable damping characteristics shock absorber includes a piezoelectric unit which serves as a sensor for detecting piston stroke and an actuator for adjusting stiffness of a flow restriction valve and thus for adjusting the damping characteristics of the shock absorber. The shock absorber includes a pair of flow restriction valves, in which one of valve is active in response to a piston bounding stroke for generating damping force by restricting the fluid flow and the other is active in response to a piston rebounding stroke for generating a damping force by restricting fluid flow. The piezoelectric unit is disposed between two valves in such a manner that it may monitor piston strokes both in the bounding and rebounding stroke directions and adjust stiffness of both of the flow restriction valves.

    摘要: A variable damping force shock absorber has a two separate bounding and rebounding fluid flow path, which the bounding fluid path is active for permitting fluid flow in a piston bounding stroke and the rebounding fluid path is active for permitting fluid flow in a piston rebounding stroke. A first flow restriction device is associated with the bounding fluid path for adjusting fluid flow path area of the bounding fluid path, which first flow restriction device is variable of magnitude of fluid flow restriction for adjusting damping characteristics for piston bounding stroke. A second flow restriction device is associated with the rebounding fluid flow path, which second flow restriction device is variable of flow restriction magnitude for adjusting damping characteristics for piston rebounding stroke. The first and second flow restriction devices are operable independently of each other.
