Abstract

A brake system damping device includes a first chamber on which hydraulic pressure is to be applied, a second chamber with a compressible medium located therein, and a first separating element configured to separate the first and second chambers. The damping device further includes a third chamber with a compressible medium located therein and a second separating element configured to separate the second and third chambers. The second and third chambers are connected in a medium-conducting manner via a passage in the second separating element. The first separating element is configured to move a closure element to close the passage when the hydraulic pressure in the first chamber has reached a predefined pressure value. The third chamber is formed by the second separating element and a cover. The second separating element is retained on the cover by an interference fit in a fluid-impervious manner.
