Summary:A pump for a high-pressure cleaning device for delivering cleaning fluid is provided. The pump has at least one pump chamber, into which at least one piston plunges, and which is connected to a suction line via at least one inlet valve and to a pressure line via at least one outlet valve. A bypass line leads from the pressure line to the suction line. An overflow valve is arranged in the bypass line. The valve body of the overflow valve is connected to a control piston which is displaceably held in a control chamber with the interposition of a sealing element and moves the valve body into a closed or an open position as a function of the flow rate of the cleaning fluid in the pressure line. A sliding element is arranged in the control chamber and abuts sealingly on the wall of the control chamber.
