Date Oct. 24, 1985.A shock-absorber is designed to be used in particular with a motor cycle or a motor car. The shock-absorber is so arranged as to permit the variation of the shock-absorbing capacity or the resistance of the shock-absorber by use of control impulses from an external computerized unit. The shock-absorber is of the kind which comprises cylinder operating with a fluid or with fluid gas. Inside the cylinder is a fixed piston which is provided with at least one passageway. In this passageway fluid is able to flow from one side of the piston to its other side, and vice versa. The piston has built into it a member capable of being controlled by the control unit and so arranged as to vary depending on the control impulses received from the control unit and so arranged as to vary depending on the control impulses received from the control unit the cross-sectional area of the passageway, causing a variation in the shock-absorbing capacity.
