  • Patent number: 11098781
    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.

  • Patent number: 10253839
    Abstract: Damping valve having a damping valve body with at least one passage channel between two cover sides. An outlet opening of the passage channel leads into a cover-side annular channel which is limited by an outer annular valve support surface and by an inner annular valve support surface, the at least one annular valve support surface for at least one valve disk has a substantially constant width along the circumference, and the annular channel has a varying width along the circumference, and at least one valve support surface has a varying radius of curvature along the circumference.
