Title: SWITCHABLE NOZZLE ARRANGEMENT
Abstract:
A switchable nozzle arrangement (10) is provided, comprising a fluid inlet device (14) and a fluid outlet device (16), which can be rotated with respect to one another around an axis of rotation (18). The fluid outlet device (16) comprises a rotary nozzle (50) and at least one additional nozzle (52, 54). Depending on the rotary position, either the rotary nozzle (50) or one of the additional nozzles (52, 54) is connected to an inlet channel (22) of the fluid inlet device (14). The rotary nozzle (50) comprises a housing (56) in which a rotor is arranged, which, via a spherical end (84) in a recess (80) on the end face and via a contact surface (98) on the circumference thereof, is supported on a support surface (100) of the housing (56). Pressurised fluid can flow into the housing via tangential inlets (62) and leave via an outlet (66), wherein the fluid moves the rotor in a circumferential movement around the longitudinal axis (76) of the housing. The at least one additional nozzle (52, 54) comprises a nozzle line (106, 110) having a nozzle body (108, 112). In order that the switchable nozzle arrangement (10) has a high cleaning performance and a high mechanical resilience, it is proposed that the rotary nozzle (50) is designed as a separate unit.
