Patent ID: 7635095

Claim:
A rotary nozzle having a nozzle housing ( 11 ) which has a swirl chamber ( 17 ) between a rear inflow opening ( 13 ) for a fluid and a front outlet opening ( 15 ), with a front end of a rotor ( 21 ), which is inclined during operation toward a longitudinal axis ( 14 ), being supported at a bearing ( 23 ) in said swirl chamber and being able to be driven by fluid flowing into the swirl chamber ( 17 ) to make a rotary movement wound the longitudinal axis ( 19 ) such that the fluid exits the nozzle housing ( 11 ) via the outlet opening ( 15 ) in the form of a conical jet; and having a gravity circuit ( 27 ) which includes at least one movable switching element ( 25 , 26 ) and which switches between at least two different operating modes by movement of the rotor nozzle in the space, characterized in that the gravity circuit ( 27 ) is arranged in the front region of the rotor nozzle downstream of the swirl chamber ( 17 ), with the switching element ( 25 , 26 ) releasing the outlet opening ( 15 ) and closing a functional opening ( 29 , 30 ) of the nozzle housing ( 11 ) provided in addition to the outlet opening ( 15 ), in one operating mode, and with the additional functional opening ( 29 , 30 ) being released in at least one further operating mode in which the outlet opening ( 15 ) is sealingly closed by the switching element ( 25 ).
