Abstract
A high pressure nozzle, including a longitudinal housing, with an internal channel therein, a nozzle head support shaft, which is rotatably arranged partially in 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. The axial bearing surface and the support shaft end surface, during use, cooperate to form an axial bearing for the nozzle head support shaft and the axial bearing seat includes an axial bore in the axial bearing surface that is aligned concentrically with an axis of rotation of the nozzle.
Claims13
A 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 end surface is located in the housing and is located opposite to an end of the rotary nozzle head support shaft at which the nozzle head is attached,
- wherein the rotary nozzle head and the nozzle head support shaft are configured to rotate with respect to the housing about a longitudinal axis of rotation to provide a rotating spray of liquid jetted from the rotary nozzle head, and
- wherein the axial bearing surface and the end surface of the nozzle head support shaft, during use, cooperate to form an axial bearing for the nozzle head support shaft to prevent the nozzle head support shaft from being displaced along the longitudinal axis of rotation by reactional forces that occur as a result of the liquid that is jetted from the rotary nozzle head, and
- wherein the axial bearing seat comprises an axial bore in the axial bearing surface that is aligned concentrically with the axis of rotation.
