Patent ID: 7118051

Claim:
A rotor nozzle, in particular for high-pressure cleaning devices, with a nozzle housing having an inlet opening at an axially first end and an outlet opening for liquid at a second end, and with a rotor, which is arranged in a turbulence chamber of the nozzle housing and which the rotor is provided at a front end facing the outlet opening with a nozzle supported in a cup bearing and which the rotor has an inflow opening, comprising: a bypass device with which the amount of liquid flowing into the turbulence chamber can be changed, wherein the flowing liquid sets the rotor into rotation; a control surface, which is funnel-like, faces a rear rotor end and is located in the turbulence chamber; and a restoring device, which is active between a front end of the rotor and the rear rotor end and in particular comprises a spring, wherein the control surface and the rear rotor end cooperate during operation, whereby the inclination of the rotor increases against the action of a restoring force of the restoring device as the rotor rotary speed increases, and the restoring device reduces the rotor inclination as the rotor rotary speed decreases.
