Abstract:
A rotor nozzle, in particular for high-pressure cleaners, comprising a housing (1) having an inner space (2) which is terminated on the inflow side by an input stopper (3) and has a pan bearing (4) for a nozzle (6) held in a rotor body (5) on the outflow side, characterizedin that the rotor body (5) is supported in the inner space (2) of the housing with a clearance adopted between a tip (7) of the nozzle (6) and the pan bearing (4) in the idle state such that a defined stroke movement of the rotor body (5) takes place in the direction of the pan bearing (4) in the start-up phase; in that the rotor body (5) is conical in shape at its end opposite the nozzle (6) and this conical surface (8) of the rotor body (5) forms a running surface; and in that the conical surface (8) of the rotor body (5) cooperates in operation with an axial thrust surface and braking surface (9) on the housing side which is fixedly arranged with respect to the housing at least in the axial direction and which exerts both an axial thrust function and a braking function for the rotor body (5) such that the rotor body (5), which adopts an increasingly inclined position in the start-up phase, undergoes an axial thrust by the axial thrust surface and braking surface (9) and thereby carries out the stroke movement in the direction of the pan bearing (4); that, after the carrying out of the stroke movement, a bracing of the rotor body (5) between the axial thrust surface and braking surface (9) and the pan bearing (4) occurs due to the increasing axial thrust, which prevents disturbing vibrations of the rotor body; and simultaneously a braking power is achieved for the rotor body (5) due to the cooperation between the conical surface (8) of the rotor body (5) and the axial thrust surface and braking surface (9) of the housing (1) by which the speed of the rotor body (5) is limited to a maximum value.
