Brake-system damping device

A brake system damping device comprising:

• a first chamber, to which hydraulic pressure is applied;
• a second chamber, in which a compressible medium is situated;
• a first separating element separating the first chamber from the second chamber;
• a third chamber, in which the compressible medium is situated;
• a second separating element separating the second chamber from the third chamber, the second separating element defining at least one passage that connects the second chamber to the third chamber in a medium-conducting manner;
• a closure element that moves together with the first separating element and is configured to close the passage as soon as the hydraulic pressure in the first chamber reaches a predefined pressure value;
• and
• a rib structure having at least one structure rib, which supports the second separating element and extends along an entire axial length of the third chamber, the at least one structure rib circumferentially separating a plurality of subchambers of the third chamber from one another.
