Abstract:
A damping valve includes a damping valve body with at least one through-channel, the outlet cross section of which is at least partially covered by at least one valve disk. The at least one valve disk is preloaded by at least two star springs. Each star spring has a support ring and a quantity of radial spring arms. The support rings lie one on top of the other in the installed position. The star springs are layered in opposite orientation such that the spring arms of at least two adjacent star springs face in the same direction with respect to the valve disk, and this star spring package has an anti-rotation element in an assembled position.
