| 摘要 |
The invention relates to a rotor nozzle, in particular for high pressure devices, having a nozzle housing which has a swirl chamber between a rear inflow opening for a fluid, in particular water, and a front outlet opening, with a front end of a rotor, which is inclined during operation toward a longitudinal axis, being supported at a bearing, in particular a cup-shaped bearing, in said swirl chamber and being able to be driven by fluid flowing into the swirl chamber to make a rotary movement around the longitudinal axis such that the fluid exits the nozzle housing via the outlet opening in the form of a conical jet, and having a gravity circuit which includes at least one movable switching element and which switches between at least two different operating modes by movement of the rotor nozzle in the space, wherein the gravity circuit is arranged in the front region of the rotor nozzle downstream of the swirl chamber, wherein the switching element releases the outlet opening and closes a functional opening of the nozzle housing provided in addition to the outlet opening, in one operating mode, and wherein the additional functional opening is released in at least one further operating mode in which the outlet opening is sealingly closed by the switching element.
