ABSTRACT:
A rotatable bearing assembly comprises a relatively fixed part and a rotatable part having a bore in which the first part extends and about the axis of which the parts are rotatable, the fixed part comprises two bodies, which are relatively axially movable and each providing one of a pair of opposed radially extending bearing surfaces co-operating with corresponding radially extending bearing surfaces on the second part, each part has a passage for fluid therethrough which passages are in communication and the bodies of the first part are relatively axially biassed in a direction to reduce the gap between the opposed bearing surfaces by the pressure of fluid in the passages. The bearing assembly is particularly designed for use in a jet or spray producing apparatus, the first part being connected to a supply of fluid under pressure and the second part to an arm carrying a nozzle, the axis of the nozzle being inclined to the plane of rotation of the arm so that fluid rising therefrom will exert a force on the arm tending to rotate it. Such an apparatus may include a speed governer whereby the inclination of the nozzle is automatically adjusted in dependence on the angular speed of the arms to maintain the angular speed constant.
