摘要： Vibration damper with amplitude-selective damping force that includes a piston rod, which is guided with freedom of axial movement in a damping medium-filled cylinder. The piston rod carries a piston arrangement, which divides the cylinder into a working space on the side of the piston with the piston rod and a working space on the side of the piston opposite the piston rod, where a flow connection, which, as a function of the movement of the piston rod, determines a damping force by means of a switching ring, which moves axially between two stop surfaces, in conjunction with at least one axially movable valve ring in a switching ring groove. The switching ring cooperates with one stop surface to form the boundaries of an annular space adjacent to the working space on the piston rod side and with another stop surface to form the boundary of an annular space adjacent to the working space on the side of the piston opposite the piston rod. The axial extension of the switching ring groove for the axially movable valve ring is large enough to guarantee that the damping medium can flow around the valve ring over a relevant stroke range of the piston rod.
