Abstract

In a piston pump, in particular, for the pressure fluid conveyance in hydraulic, slip-controlled brake systems, comprising at least one piston, a suction valve and a pressure valve, it will be possible for the suction and pressure valves to be externally checked in that the suction valve and the pressure valve are formed on a structural unit adapted to be separately handled. Preferably, the structural unit comprises a sleeve-type section in which the piston is guided.
