Abstract

In a rotor nozzle for a high-pressure cleaning device comprising a housing, a rotor rotatably mounted therein and set in rotation by a cleaning liquid, and a nozzle arranged downstream of the rotor with its outlet axis including a variable, acute angle with the axis of rotation of the rotor and rotated by the rotor about the axis of rotation thereof so that the jet of cleaning liquid issuing from it flows around the lateral area of a cone, to enable adjustment of the outlet angle of the point jet without having to change any other parameters, it is proposed that adjustable stops be arranged in the housing to limit to a greater or lesser extent the widening of the acute angle between the outlet axis of the nozzle and the axis of rotation of the rotor in accordance with the position of the limiting elements.
