Abstract
A shock absorber in which a damping force is to be adjusted separately for the tension and the compression directions in which the shock absorber is equipped with separate throttle valves, one for basic damping and one for supplementary damping. In the device, the adjustable parts of the two throttle valves are embodied in the form of magnetically controllable coaxial sheaths. This results in an especially space-saving design, the sheaths and magnetic coils which can be integrated directly into a piston (5) of the shock absorber. The device is used for damping relative motions of two masses, in particular in resilient wheel suspension systems in vehicles.
