Abstract
A damping valve for a vibration damper includes a damping valve body with at least one through-channel, the outlet side of which is at least partially covered by at least one valve disk. The at least one valve disk lifts from a valve seat surface when there is an incident flow via the through-channel, and a supporting disk, as stop, limits the lift movement. An elastomer intermediate layer is arranged between the supporting disk and the valve disk. The elastomer intermediate layer is formed by an elastomer ring which has at least one raised deformation area in direction of the valve disk and/or supporting disk.
