Abstract

In a piston pump (1), in particular for pressure medium delivery in slip-controlled hydraulic brake systems, including a suction valve (82) and a delivery valve (81), external preassembly and possibilities of external testing of the delivery and suction valves (81,82) result from providing the suction valve (82) and the delivery valve (81) within a component (8) which can be handled independently. The component (8) preferably includes a delivery valve (81) provided radially to the center line and a valve seat member (70), with a valve body (95) of the delivery valve (81) being prestressed by a tongue (121) of a clamp (120), placed onto the valve seat member (70), against a valve seat (96) formed within the valve seat member (70).
