Abstract
A piston pump for a high-pressure cleaning device is provided, having a pump housing, which includes a first housing part and a second housing part. The first housing part forms a suction conduit and a pressure conduit, and the second housing part forms a plurality of pump chambers into each of which a reciprocally movable piston dips and which are each in flow connection with the suction conduit by way of an inlet channel and with the pressure conduit by way of an outlet channel. The inlet channel can be closed by an inlet valve and the outlet channel can be closed by an outlet valve. The second housing part includes a valve receptacle, and that the piston pump includes an outlet valve assembly, wherein the outlet valve assembly comprises an outlet part, which is inserted into the valve receptacle and forms all outlet valve seats.
