Abstract
A piston pump for a slip-controlled motor vehicle brake system, with a piston which, by means of a piston restoring spring, is pressed with an end face that constitutes a strike face against a circumference of a cam. The cam is driven to rotate, wherein the cam is used to drive the piston in a reciprocating stroke motion. In order to be able to inexpensively manufacture the piston as an injection molded part made of plastic, the piston is provided with a cam strike piece made of wear resistant material on the strike face which is in contact with the cam.
