Abstract
A piston pump, which is provided as a return feed pump for a slip-regulated motor vehicle brake system. In order to simplify the manufacture, a sleeve in the form of a tubular piece is clamped between a fastening element which is inserted into the cylinder bore using a self-clinching technique, and the cylinder bore, and is thus sealed and fixed in place. In addition to the simple manufacture of the sleeve out of reasonably priced tubular material, the piston pump has the advantage of a sealing of the sleeve in the cylinder bore without a separate sealing element such as a sealing ring.
