    • 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.

    • The invention relates to a swash drive for a high-pressure cleaning appliance, having a swash body which can be driven in rotation about an axis of rotation, and having a swash plate which is inclined in relation to the axis of rotation and on the face of which there can engage pistons of a piston-pump which are movable back and forth parallel to the axis of rotation, the swash body butting against a supporting plate via a supporting bearing and a swash-plate bearing being disposed between the swash body and the swash plate. In order to develop the swash drive such that it is possible to increase the inclination of the swash plate without any risk of damaging the supporting bearing, it is proposed according to the invention that the supporting bearing be configured as an angular-contact ball bearing, the swash body supporting the bearing balls of the supporting bearing on the outside.

    • A wobble drive in an axial piston machine, particularly the axial piston pump of a high-pressure cleaning device, having a wobble body (1) rotatable around an axis of rotation (D) and a wobble plate (2) driving with its front side at least one piston (10a) positioned parallel to the axis of rotation D, a roller bearing (3) positioned between the wobble body (1) and the wobble plate (2) exhibiting a bearing axis inclined to the axis of rotation (D). In order to insure even at elevated rotary speeds of the wobble body (1) and thus also of the rolling bodies (6) that the rolling bodies (6) are securely held in their races (4,5) in spite of the elevated centrifugal forces acting on them, it is proposed that the wobble plate (2) be provided with a rim (7) overlapping the wobble body (1), with the rolling bodies (6) being positioned between the rim (7) and the wobble body (1).

    • In a high-pressure cleaning apparatus comprising an electric motor, a high-pressure pump driven by the electric motor, and an automatic switching-off means for the electric motor including a switch actuatable by an actuating element moveable in dependence upon the pressure or the flow of the liquid being conveyed by the high-pressure pump, in order to reduce the switching expenditure it is proposed that a switching-off element which is manually actuatable on the high-pressure cleaning apparatus be associated with the same switch so that in one position of the switching-off element, the switch cuts off the power supply to the electric motor independently of the pressure or the flow of the liquid being conveyed, whereas in the other position the switch is actuatable by the actuating element.
