Abstract:
Apparatus for ejecting liquid comprising a plurality of rotor nozzles combined into a unit, each rotor nozzle including a nozzle housing defining a rotor space and having an inlet opening at one axial end of the rotor space and an outlet opening at another axial end of the rotor space through which liquid can flow, a cup bearing at an end of the rotor space proximate the outlet opening, a rotor arranged in the rotor space, the rotor being movable relative to a longitudinal axis of the rotor space and including a nozzle region at an end of the rotor facing the outlet opening, the nozzle region being supported by the cup bearing, a passage in the rotor terminating at an end of the rotor and in flow communication with the outlet opening in the housing, the rotor being inclined relative to the longitudinal axis of the rotor space and supported by an inner wall of the rotor space, and at least one common supply space for flowing the liquid to the plurality of rotor nozzles, the supply space communicating with the rotor spaces of the rotor nozzles so that, during operation, liquid flowing from the supply space into the rotor spaces swirls within the rotor spaces, thereby causing the rotors to be rotationally driven in the rotor spaces.
