DAMPING VALVE ARRANGEMENT HAVING A MULTI-STEP DAMPING FORCE CHARACTERISTIC

摘要

The present invention comprises a main valve body (2) and a first additional valve body (3) having two or more flow-through channels (5a, 5b, 6a, 6b, 6c) connected hydraulically in parallel for the direction of flow of the damping medium; and a damping valve arrangement (1) for a vibration damper comprising a second additional valve body (4), wherein the discharge cross-sections (7a) of two or more flow-through channels (5a, 5b, 6a, 6b, 6c) , 7b, 8a, 8b are respectively influenced by one or more valve discs 9 , 10 , 11 , the valve bodies 2 , 3 , 4 being axially fixed on a common carrier 12 , wherein the carrier 12 extends through the valve bodies 2 , 3 , 4 and at least one of the flow-through channels 6a , 6b , 6c is implemented on the carrier 12 , the first additional valve A first additional valve 13 comprising a body 3 and at least one first valve disc 10 , and a second comprising a second additional valve body 4 and at least one other separate valve disc 11 . The additional valve 14 is connected to each other via common flow-through channels 6a, 6b, 6c and connected in hydraulic series, such that the flow-through amount of the damping medium flowing through the second additional valve 14 is reduced by the first additional valve. (13) is limited by
