Abstract
Damping valve comprising a damping valve body with a through-channel system, which is covered on at least one outlet side by a number of valve disks, where a nonreturn valve disk releases an advance cross section when the damping medium is flowing in one direction and closes off that cross section when the damping medium is flowing in the other flow direction, and where a cover disk with at least one cross section which can be actuated by the nonreturn valve disk limits the lifting movement of the nonreturn valve disk, and where a second cover disk limits the lifting movement of the nonreturn valve disk in the direction opposite that in which the first cover disk works.
