A damping valve (1) for a vibration damper, comprising a damping valve body (7) with separate passage channels (9, 11) for different flow directions, wherein outlet openings (17) of at least two passage channels (9a, 9b) are connected to each other via a trench (35) and at least one valve disc (21) which covers the trench and rests on a valve seat surface (37) first of all lifts off at a defined point and subsequently, starting from there, lifts off the rest of the circumference. The passage channels run parallel to a centre axis of the damping valve body, and a web (39) forming the valve seat surface separates the group of passage channels (9) for one flow direction from the group of passage channels (11) for the other flow direction, wherein the distances (A1, A2, A3) of the valve seat surface from the centre axis differ in design in the region of at least two outlet openings of at least one group of passage channels. |
