High-pressure rotor nozzle

A high-pressure rotor nozzle, comprising:

• a main body having a channel configured to supply a liquid under high pressure, and
• a nozzle holder rotatably drivable by a hydraulically generated torque and having at least one nozzle which is in connection in a liquid-open manner with the channel and causes an axial recoil in operation,
• wherein a leakage chamber forming a hydraulic axial bearing in operation is provided between the main body and the nozzle holder that can be axially adjusted in relation to the same in a recoil-dependent manner, with said leakage chamber being connected to a first gap seal, guiding a leakage fluid between the main body and the nozzle holder,
• wherein the leakage chamber changes into at least one throttle gap circumferentially surrounding the nozzle holder in an axial sub-region and varying in an axial extension thereof according to a movement path of the nozzle holder,
• wherein the throttle gap remains a same height over an axial length thereof;
• wherein the nozzle holder includes a support sleeve and an outer sleeve encompassing and connected to the support sleeve, the support sleeve having an inner surface and an outer surface, and
• wherein a concentric annular gap is delimited by the outer surface of the support sleeve and the inner surface of the outer sleeve.
