Abstract

A pressure variation damper for a slip-regulated, hydraulic vehicle brake system includes a damper housing and a tubular damper element. The damper element is disposed in the damper housing and configured for elastic deformation. The damper element is subjected on an inside and/or on an outside to a fluid. Possible pressure variations of the fluid are to be damped. The damper element comprises a corrugation on the outside and a corrugation on the inside configured to reduce a change in a wall thickness of the damper element owing to the corrugation on the outside.
