Abstract
The invention relates to a damping valve for a vibration damper, comprising a damping valve body having at least one through channel, the outlet opening of which is covered by at least one valve disk, wherein the valve disk is prestressed in the closing direction by at least one elastomer element which is supported on a support disk, wherein the elastomer element has a nodal web, from which extend at least two spring webs in an oblique manner.
