Abstract

The invention provides a rotor nozzle, comprising a casing and a rotor body arranged therein. The rotor body has a flow-through channel and a spherical bearing part in a step bearing surrounding an exit opening of the casing. An end part closes the casing and has several selectively closable passages arranged therein which open from an inlet side into the interior of the casing or into flow channels in the casing leading to additional outlets. The end part widens in steps from the interior to the inlet side, and is inserted into a stepped receiving opening. A seal is provided between the end part and the inner wall of the receiving opening. An outlet for a passage of the end part is arranged in the area of at least one step and a flow channel begins in the casing in the area of this step.
