Patent attributes
The invention relates to a rotor nozzle, in particular for high pressure cleaning devices, having a nozzle housing which has a swirl chamber between an inflow opening for a fluid, in particular water, and a discharge opening, with a rotor inclined with respect to a longitudinal axis during operation being supported at its front end at a bearing, in particular at a cup-shaped bearing, in said swirl chamber and with the rotor being able to be driven to make a rotating movement around the longitudinal axis by fluid flowing into the swirl chamber, wherein an adjustment device is positioned in front of the swirl chamber for the speed regulation of the rotor and forces the inflowing fluid to make a rotary movement around the longitudinal axis for the generation of a rotating fluid field before the transition into the swirl chamber, and wherein the rotating fluid field is disrupted more or less pronouncedly on the transition into the swirl chamber in dependence on the position of the adjustment device.
