<p>A VARIABLE-THROTTLE VALVE The valve is mounted within the piston of a hydraulic shock-absorber for a vehicle suspension system. An axial rod attached to the piston is surrounded by a passageway and fitted with a moving element consisting of an elastically deformable washer which moves between two end positions defined by stops. In one end position, the cross-sectional area permits free flow of the operating fluid between the wall of the passageway and the washer. In the other end position, the passageway is throttled and the flow is limited in respect of a fluid pressure below a predetermined threshold value. In the throttling position the washer is capable of undergoing elastic deformation in respect of a fluid pressure above the threshold value in order to increase the flow crosssection.</p> |
