ABSTRACT:
In a pump having a piston, supported displaceably in a pump cylinder, for aspirating a pressure fluid via a feed line and for expelling this pressure fluid into a line, particularly a brake line, the pump cylinder is intended to rest with a stop ring on a shoulder of the housing. This housing shoulder is adjoined by an annular chamber having a filter, which toward the housing forms an annular gap into which the feed line for pressure fluid discharges. The pump cylinder stop ring is intended to include a radius of curvature and to rest on the housing shoulder, also having a radius of curvature in the region of a bearing face.
