The invention relates to a self-regulating shock absorber, especially for motor vehicles, consisting of a cylinder which is closed on both walls and is filled with a damping medium, and having a piston rod which is inserted into the cylinder in a sealed manner and divides said cylinder into two chamber halves. In its upper part, the piston rod has radial perforations which can be closed by an electrically controlled control slide, which can be moved by means of a coil which is arranged on the piston rod, the control slide being a sleeve-shaped rotary slide which coaxially surrounds the piston rod in the region of the perforations and has radial openings in its wall corresponding to the number of perforations, which openings to a greater or lesser extent open the perforations on rotation of the rotary slide relative to the piston rod, and the rotary slide being constructed as the rotor of a stepping motor, according to Patent Application P 3312899.5. The radial perforations within the piston rod are holes which are arranged one above the other or side-by-side, the number of which corresponds to the number or a multiple of the steps of the rotary slide, the rotary slide having holes in its jacket wall which are allocated in lines or rows, and the number of lines or rows corresponding to the number or a multiple of the steps of the rotary slide. The clear area of the hole or of the holes at each line or row thus rises by the single, or the multiple of the number of steps, of the ... Original abstract incomplete. <IMAGE>
