High pressure nozzle

High pressure nozzle, comprising:

• a longitudinal housing, comprising a liquid inlet end and a liquid outlet end opposite to the liquid inlet end and comprising an internal channel running from the liquid inlet end to the liquid outlet end,
• a nozzle head support shaft, which is rotatably arranged partially in the housing and in part of the internal channel and which comprises a liquid channel in fluid communication with the internal channel,
• a rotary nozzle head, which is attached to the nozzle head support shaft and arranged outside the housing, and
• an axial bearing seat which is located within the housing and which comprises an axial bearing surface that faces an end surface of the nozzle head support shaft,
• wherein the rotary nozzle head and the nozzle head support shaft are configured to rotate with respect to the longitudinal housing about a longitudinal axis of rotation to provide a rotating spraying of liquid jetted from the rotary nozzle head, and wherein the axial bearing surface and the support shaft end surface, during use, cooperate, e.g. contact each other, to form an axial bearing for the nozzle head support shaft, and
• wherein the axial bearing seat comprises an axial bore in the axial bearing surface that is aligned concentrically with the axis of rotation.
