Rotor nozzle for a high-pressure cleaning apparatus

A rotor nozzle for a high-pressure cleaning apparatus with a housing having at least one inlet opening tangentially and an outlet which is arranged on an end wall of the housing and on which is arranged a bearing with a pan-shaped, centrally broken recess, and with a nozzle body which is arranged in the housing, has a through channel, and is supported with a spherical end in the pan-shaped recess, the longitudinal axis of which nozzle body is tilted toward the longitudinal axis of the housing and which nozzle body is brought into a revolving movement by the liquid flowing through the housing, in which revolving movement the longitudinal axis of the nozzle body revolves on a conical shell and the nozzle body is supported with a contact surface on its circumference on a support surface, wherein several flow resistance elements are arranged downstream of the support surface on the wall of the housing in the circumferential direction at a distance to one another, which flow resistance elements respectively have one baffle surface protruding into the housing for impinging liquid, wherein a guiding surface is arranged directly upstream of each baffle surface with respect to the flow direction of the liquid, which guiding surface is continuously adjoined by the baffle surface, wherein the guiding surface is aligned obliquely to a radial plane with respect to the longitudinal axis of the housing.
