Claims
- 1. A high pressure cleaning device comprising:
- a piston pump having pistons drivable by a motor via a wobble plate;
- said wobble plate being mounted to a plastic coupling element via a form locking connection, said coupling element being attached to a motor shaft of said motor for non-rotatably connecting the wobble plate to the motor shaft; and
- a tension rod held in the motor shaft for tensioning an end face of said coupling element to an end face of the motor shaft to form a friction contact;
- wherein the coupling element comprises a sleeve pushed onto a circular cross section of the motor shaft having a smaller external diameter than a region of the motor shaft adjoining the sleeve, said sleeve bearing at its free end an annular collar projecting in a step-like manner and extending around said region of the motor shaft in a circumferential direction.
- 2. A high pressure cleaning device as defined in claim 1, wherein the tension rod also tensions the wobble plate against the coupling element in the direction of a longitudinal axis of the motor shaft.
- 3. A high pressure cleaning device as defined in claim 1, wherein the tension rod comprises a tightening screw screwed into the end face of said motor shaft.
- 4. A high pressure cleaning device as defined in claim 2, wherein the tension rod comprises a tightening screw screwed into the end face of said motor shaft.
- 5. A high pressure cleaning device as defined claim 1, wherein the coupling element has two lateral flattened areas located opposite one another abutting on the longitudinal edges of a central elongated hole in the wobble plate.
- 6. A high pressure cleaning device as defined claim 2, wherein the coupling element has two lateral flattened areas located opposite one another abutting on the longitudinal edges of a central elongated hole in the wobble plate.
- 7. A high pressure cleaning device as defined claim 3, wherein the coupling element has two lateral flattened areas located opposite one another abutting on the longitudinal edges of a central elongated hole in the wobble plate.
- 8. A high pressure cleaning device as defined in claim 5, wherein the flattened areas end in a step, and the wobble plate abuts on said step due to the tension rod.
- 9. A high pressure cleaning device as defined in claim 6, wherein the flattened areas end in a step, and the wobble plate abuts on said step due to the tension rod.
- 10. A high pressure cleaning device as defined in claim 7, wherein the flattened areas end in a step, and the wobble plate abuts on said step due to the tension rod.
