Abstract:
A damping valve arrangement of a vibration damper for a motor vehicle includes a damping valve body having a longitudinal axis A and a throughflow passage is covered by at least one valve disk, a spring arrangement has at least a first substantially disk-shaped spring element; and a force transmission disk arranged between the valve disk and the first spring element so as to be axially displaceable coaxial to the damping valve body. The force transmission disk has a first surface facing the first spring element and comprising a first contact ring with a first diameter, which first contact ring is axially elevated above the first surface, and a second surface opposite the first surface, which second surface faces the valve disk and comprises a second contact ring with a second diameter, which second contact ring is axially elevated above the second surface.
