Abstract:
A damping valve arrangement for a vibration damper includes a damping valve body, which has at least one through-flow opening for the damping medium, and at least one valve disk which at least partly covers the through-flow openings under the influence of a closing force. The damping valve arrangement includes at least one spring element which has at least one supporting portion axially supported at another structural component part of the damping valve arrangement, and at least one spring portion disposed at a distance from the supporting portion and which introduces a spring force into the valve disk at least indirectly, wherein the spring force of the spring element is directed counter to the closing force acting on the valve disk, and wherein the spring force of the spring element is less than the closing force of the valve disk.
