Abstract
A vibration damper, whose cylinder tube is divided into two work chambers by a piston, is attached to a piston rod. A damping valve includes a damping valve body. Embossed areas have been formed into the main body of the damping valve body. The damping valve embossed areas serve as valve support surfaces with fluid passages, which fluid passages are covered by valve disks on the valve support surfaces. The damping valve body is disk-shaped, whereby the damping valve is equipped with at least one restrictor plate, which restrictor plate partially covers the inlet side of the fluid passages for at least one direction of flow, whereby the restrictor plate has recesses for the embossed areas of the damping valve body.
