Damping Valve Arrangement With A Multistage Damping Force Characteristic

摘要

A damping valve arrangement for a vibration damper has a main valve body, a first auxiliary valve body and a second auxiliary valve body with at least two through-flow channels connected hydraulically in parallel for a flow direction of a damping medium. Outlet cross sections of the at least two through-flow channels are influenced by at least one valve disk. The valve bodies are axially fastened to a shared support that extends through the valve bodies and at least one through-flow channel is formed at the support. A first auxiliary valve including the first auxiliary valve body and at least a first valve disk and a second auxiliary valve including the second auxiliary valve body and a, separate valve disk connected through a shared through-flow channel and are hydraulically connected in series such that the amount of damping medium flowing through the second auxiliary valve is limited by the first auxiliary valve.

1. A damping valve arrangement (1) for a vibration damper, comprising:
a main valve body (2); a first auxiliary valve body (3); a second auxiliary valve body (4); at least two through-flow channels (5a, 5b, 6a, 6b, 6c) arranged in the a second auxiliary valve body that are connected hydraulically in parallel for a flow direction of a damping medium; outlet cross sections (7a, 7b, 8a, 8b) of the at least two through-flow channels (5a, 5b, 6a, 6b, 6c) are influenced by at least one valve disk (9, 10, 11); and a shared support to which the main valve body, the first auxiliary valve body, and the second auxiliary valve body (2, 3, 4) are axially fastened, wherein the shared support (12) extends through the main valve body, the first auxiliary valve body, and the second auxiliary valve body, wherein at least one of the through-flow channels (6a, 6b, 6c) is formed at the shared support (12), wherein a first auxiliary valve (13) comprising the first auxiliary valve body (3) and at least a first valve disk (10) and a second auxiliary valve (14) comprising the second auxiliary valve body (4) and at least a further valve disk (11) are connected to one another through a shared through-flow channel (6a, 6b, 6c) and are hydraulically connected in series such that an amount of damping medium flowing through the second auxiliary valve (14) is limited by the first auxiliary valve (13).
