Claims
- 1. A rotary nozzle for a high-pressure cleaning apparatus, comprising:
- a housing into which a feed line for a cleaning fluid issues;
- an outlet provided in said housing for expelling the cleaning fluid;
- a nozzle body through which the cleaning fluid flows; and
- a bearing that surrounds the outlet; wherein:
- said nozzle body is disposed in the housing and has a convex end;
- said nozzle body is supported at its convex end in the bearing;
- said nozzle body is set by the flow of cleaning fluid through the housing in a revolving movement in which a longitudinal axis of the nozzle body revolves on a generated cone; and
- the bearing is formed by a conically-shaped depression which is provided in an inner wall of the housing and is disposed concentrically relatively to the outlet.
- 2. The rotary nozzle of claim 1, wherein:
- an aperture angle of the depression lies between approximately 110.degree. and approximately 150.degree..
- 3. The rotary nozzle of claim 1, wherein:
- the convex end is spherical shaped.
- 4. The rotary nozzle of claim 3, wherein;
- a radius of the convex end lies between approximately 3 mm and approximately 7 mm.
- 5. The rotary nozzle of claim 1, wherein:
- the housing comprises plastics material.
- 6. The rotary nozzle of claim 5, wherein:
- the housing comprises polyamide.
- 7. The rotary nozzle according to claim 6, wherein:
- the polyamide contains a proportion of glass fibre.
- 8. The rotary nozzle of claim 1, wherein:
- the housing comprises a housing base into which the feed line issues, and a housing hood connectable to the housing base; and
- the outlet and the depression are provided in the housing hood.
- 9. The rotary nozzle of claim 8, wherein:
- the housing base and housing hood are connectable to one another by screwing.
- 10. The rotary nozzle of claim 1, wherein:
- the nozzle body comprises a tubular body, and a nozzle introduced into the tubular body; and
- said nozzle forms the convex end of the nozzle body.
- 11. The rotary nozzle of claim 1, wherein:
- the nozzle body comprises a tubular body; and
- one end of the tubular body forms the convex end of the nozzle body.
- 12. The rotary nozzle of claim 1, wherein:
- the nozzle body comprises plastics material, at least in an area of the convex end.
- 13. The rotary nozzle of claim 12, wherein:
- the nozzle body comprises polyether ether ketone, at least in an area of the convex end.
- 14. The rotary nozzle of claim 1, wherein:
- an aperture angle of the depression lies between approximately 120.degree. and approximately 140.degree..
