In a connector provided with a coupling ring for the pipe coupling of a high-pressure cleaning apparatus, the pipe coupling comprising a coupling sleeve with a conical sealing surface, a circular-cylindrical sealing surface adjacent thereto, and an outer thread for the coupling ring of the connector, with a cylindrical nipple carrying a ring seal and sealingly positionable at the circular-cylindrical sealing surface of the coupling sleeve, and a convex sealing shoulder for sealing abutment on the conical sealing surface of the coupling sleeve, the coupling ring being mounted on the connector so as to be freely rotatable and essentially immovable in the axial direction, in order to improve the mechanical protection of the coupling parts against damage, it is proposed that the coupling ring protrude in the axial direction over the free end of the nipple, and that the ratio of the length of the nipple to the outer diameter thereof be between 0.4 and 0.3.

Rotor nozzle for a high-pressure cleaning device

A spray nozzle arrangement is provided for high pressure cleaning apparatus with an outlet nozzle of circular cross-section. A deforming member is arranged downstream of the nozzle and comprises two swing elements having substantially planar faces. The swing elements pivot about a rotary axis perpendicular to the jet. Thus, the two faces can be inclined symmetrically relative to the jet axis so that the region of the faces remote from the outlet nozzle enter the round jet, resulting in a fan-shaped jet.

Spray nozzle arrangements for high pressure cleaning apparatus

A nozzle for spraying a medium under pressure has a selectable form of jet. A knife edge body is rotatably mounted in front of the outlet from the nozzle bore, and has a front knife edge which breaks the jet from the bore into a spray mist when that knife edge is rotated into the jet and a rear knife edge which spreads the jet to a fan-shape when it is rotated into the jet.
