Damping valve device for a shock absorber of a motor vehicle

Abstract

A vibration damper of a motor vehicle comprises an outer tube and an inner tube which is arranged so as to be coaxial with the latter, and a working piston which is arranged so as to be axially movable within the inner tube and divides the interior of the inner tube into a first, piston rod-proximal working chamber and a second, piston rod-distal working chamber, a damping valve device which is arranged, for example, in the working piston, wherein the damping valve device has: a coil, an axially movable armature which is at least partially arranged within the coil, a main valve having a main piston which separates a compression main control chamber and a rebound main control chamber from one another, wherein a preload element is provided which lies against the main piston in such a way that it applies a force to the main piston in the opening direction of the main valve.
