Shock absorber for motor vehicles, on which there is a damping element, which exhibits a working cylinder to hold a working medium, divided by a piston into two working chambers, whereby an electromagnetically-activated and axially-movable valve body of the valve pressurizes a flow passage, at least partly to control the damping force. The object of the invention is to make possible a variable damping adjustment, whereby by means of a variably-controllable damping valve, an adjustable damping of the decompression and compression stages can be achieved. In addition, by variation of the effective hydraulically-influenced functional surfaces of the valve body, the switching, frequency, closing and opening action of the valve body, designed as the armature of an electromagnet, can be influenced. The object is achieved by the formation of a valve seat by a seat surface oriented at approximately right angles to the valve body, together with the end surface of the valve body and of the valve seat are at a distance from one another. As a result of this configuration, a partial pressure reduction can be achieved in the vicinity of the valve seat, which influences the valve body.
