Abstract
A vibration damper for vehicles is described, the damper curve of which is required to be arbitrarily variable, to enable the damping to be adapted optimally to driving conditions. For this purpose, the invention has a vibration damper in which a regulating member actuable by an actuating device can be pressed with variable force against at least one spring washer of a valve closure element of a damping valve arranged in the damper piston. The contact pressure of the regulating member is arbitrarily variable and the regulating member can be pressed progressively against the spring washer of the valve closure element upon an increase of force in the radial direction.
