摘要
A hydraulic shock-absorber and vibration damper comprising a cylinder (1), a damping piston (2) disposed so as to be axially movable inside the cylinder (1) and dividing off two working chambers (9, 10) filled with a hydraulic damping medium and connected by at least one throttle means (62) , a piston rod (3) connected to the damping piston (2) and guided in sealing-tight manner out of the cylinder (1), and a compensating chamber (11) connected to one (9) of the working chambers (9, 10) for receiving a volume of damping medium displaced by the piston rod (3). A damping valve (26) driven by an electromagnet (24) and acted upon by a closing force is disposed at the transition between the working chamber (9) and the compensating chamber (11). The damping valve (26) is disposed in series with the throttle means (62), so that all the damping medium flowing between the working chamber (9) and the compensating chamber (11) flows through the damping valve (26). The electromagnet (24) is connected to a valve body (30) of the damping valve (26) so that its closing force can be varied directly via the electromagnet (24).
