Abstract

See full text

An accumulator piston, in particular a piston for a pressure medium accumulator of a hydraulic unit of an electronically slip-controllable vehicle brake system, includes a cylindrical piston shaft, and a piston head covering the piston shaft. The piston head includes a circumferentially closed blind-hole-shaped recess having an opening. A cross section of the recess in a region of the opening has at least one smaller dimension than a cross section in a region of a base of the recess opposite the opening. The recess forms a mechanism configured to separate particles out from the pressure medium.
