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.

Device for damping courses of motion between two suspension points

A pneumatic suspension intended for motor vehicles that is equipped with an additional volume. An adjusting piston defining the additional volume separates two work chambers from one another, which can be disconnected from one another or made to communicate with one another via a connecting line and a valve assembly in the connecting line. When the work chambers are in communication, the spring rate of the suspension is variable without force.
