A rotor bearing for bearing a rotor hub on a nacelle housing of a nacelle for a wind turbine has at least one inner ring element and at least one outer ring element, wherein at least one sliding bearing element is arranged between the inner ring element and the outer ring element, which sliding bearing element is fastened to the inner ring element or to the outer ring element. On the sliding bearing element, a sliding surface is formed, which cooperates with a counterface, which is coupled with that ring element, to which the sliding bearing element is not fastened. The counterface is designed to be resilient.

A nacelle for a wind turbine includes: a nacelle housing; a rotor hub; and a rotor bearing for bearing the rotor hub on the nacelle housing, wherein the rotor bearing has at least one inner ring element and at least one outer ring element, wherein at least one oil-lubricated sliding bearing element is formed between the inner ring element and the outer ring element. In the nacelle housing and/or in the rotor hub, a lubricating oil sump is formed in such a manner for receiving a lubricating oil for the sliding bearing element. The lubricating oil sump can be filled with lubricating oil up to a lubricating oil level, wherein at least a section of the rotor bearing is arranged in the lubricating oil sump vertically below the lubricating oil level.

The invention relates to an exhaust-gas-driven turbocharger having a hydrodynamic plain bearing having a rotor and a stator, the rotor being rotatable with respect to the stator, the rotor bearing surface being located opposite a counter-surface of the stator in order to generate hydrodynamic pressure in the region of a converging gap. In such a hydrodynamic plain bearing, the application properties can be improved by the fact that the rotor bearing surface and/or the counter-surface constitutes in a section view, in the context of a section along and through the rotation axis, a continuous bearing contour that is constituted from convex or concave curvatures and/or from at least two contour segments that are embodied as straight lines and/or curvatures. The invention also relates to a hydrodynamic plain bearing or bearing arrangement having such a plain bearing.

The invention provides a high pressure nozzle (1), comprising: .Math.a longitudinal housing (2) having a liquid inlet end (3) and a liquid outlet end (4) opposite to the liquid inlet end and comprising an internal channel (8) running from the liquid inlet end to the liquid outlet end, .Math.a nozzle head support shaft (9), rotatably arranged partially in the internal channel (8) and comprising a liquid channel (22) in fluid communication with the internal channel, and .Math.a rotary nozzle head (10) supported on the nozzle head support shaft and arranged outside the housing, wherein the rotary nozzle head is arranged to rotate about a longitudinal axis of rotation (A) to provide a rotating spraying of liquid jetted from the rotary nozzle head, characterized in that the high pressure nozzle comprises an axial pressure compensator (12) arranged in the internal channel, wherein the axial pressure compensator is arranged to substantially compensate axial pressure force from liquid entering the channel at the liquid inlet end.
