Abstract
A shock absorber including an electromagnetically actuatable control piston located in a damper piston within a cylinder. The damping force is determined directly with the triggering of the magnet coil, regardless of the relative speed between the piston and the cylinder. To control the forces, a first single valve is electrically acted upon, and that valve in turn acts upon a second single valve. The apparatus is used for damping relative motions of two masses, in particular with resilient wheel suspension systems in motor vehicles.
