Abstract:
1. A rotor nozzle, in particular for high-pressure cleaning devices, having a nozzle housing which has an inlet opening for liquid at its axially one end and an outlet opening for liquid at the other end as well as having a rotor which is arranged in a swirl chamber of the nozzle housing, which has a front end facing the outlet opening and supported at a bearing, which can be at least partly flowed through by the liquid, which can be set into rotation around a longitudinal axis by liquid flowing into the swirl chamber and which is inclined toward the longitudinal axis at least in the rotating state; wherein the rotor has an inlet region for the liquid via which the liquid can move out of the swirl chamber into the rotor to allow a rotor flow of the liquid from the inlet region up to the front end of the rotor and out of the outlet opening; wherein the rotor nozzle is capable of a switchover procedure between a stationary state in which the rotor is held tight between the bearing and an abutment and a rotational state in which the rotor is out of engagement with the abutment; wherein the switchover procedure is triggerable by the rotor flow building up on the start-up of the rotor nozzle and/or by pressure relationships and/or flow relationships being adopted at and/or in the rotor; and wherein the rotor has at least one elastically deformable device whose deformation is accompanied by a length change of the rotor.
