Abstract

In a piston pump, in particular for pressure medium delivery in slip-controlled hydraulic brake systems, including a suction valve and a delivery valve, external preassembly and possibilities of external testing of the delivery and suction valves result from providing the suction valve and the delivery valve within a component which can be handled independently. The component preferably includes a delivery valve provided radially to the center line and a valve seat member, with a valve body of the delivery valve being prestressed by a tongue of a clamp, placed onto the valve seat member, against a valve seat formed within the valve seat member.
