Apparatus for the ejection of liquid
First Claim
1. 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.

Abstract
The invention relates to an apparatus for the ejection of liquid comprising a plurality of rotor nozzles which are combined into a unit. Each rotor nozzle has a rotor space formed in a nozzle housing and an inlet opening in the region of its one axial end and an outlet opening for the liquid at the other end, as well as a rotationally driven rotor arranged inclined in the rotor space relative to its longitudinal axis and supported at the inner wall of the rotor space. The rotor has a nozzle region supported in a cup bearing at its end pointing towards the outlet opening and an inflow opening at the opposite end.

30. Apparatus for ejecting a liquid comprising a housing forming first and second rotor spaces, each rotor space including a liquid inlet at one end of each rotor space, an outlet at another end of each rotor space and an inner wall between the ends so that the liquid can flow into and out of each rotor space, a cup bearing in each rotor space located proximate the outlet thereof, and an elongated rotor in each rotor space, an end of the rotor being loosely supported by the cup bearing and the inner wall of each rotor space being sized so that the inner wall maintains the rotor, when supported by the cup bearing, in an angularly inclined position relative to a longitudinal axis of the rotor space, each rotor further having an internal passage for flowing the liquid from each rotor space along the passage through the outlet opening to an exterior of the housing while the inner wall of each rotor space limits the angular inclination of the rotor and permits the rotor to rotate along a substantially conical path having an apex proximate the outlet opening, and at least one common supply space communicating with each rotor space so that liquid flowing from the at least one supply space into each rotor space causes liquid in each rotor space to swirl to thereby rotate each rotor along a substantially conical path.
