Abstract
A high-pressure cleaning apparatus including a high-pressure pump that includes a suction chamber, at least one pump chamber in which liquid is pressurized, and a pressure chamber arranged downstream of the pump chamber is disclosed. The high-pressure pump includes a return line via which the pressure chamber is in flow communication with the suction chamber, and a valve unit by which a free cross-sectional area of the return line is changeable. The high-pressure cleaning apparatus also includes a drive unit associated with the valve unit, a control unit coupled to the drive unit and a pressure sensor coupled to the control unit for detecting liquid pressure on the pressure side of the pump chamber. Depending on the signal of the pressure sensor, the liquid pressure can be controllable to a predetermined or predeterminable liquid pressure by changing of the free cross-sectional area of the return line.
