ABSTRACT:
A rotary motor which is propelled by a jet of high-pressure fluid comprising an annular rotor having a diameter much greater than its thickness and its width and a roughened annular surface, a housing having a smooth annular surface apposed to the roughened annular surface of the rotor, bearing means comprising apposed annular races separated by rolling means and united in freely rotating, inseparable relation one to the other and to the rolling means. The races have an inside diameter at least equal to the inside diameter of the annular rotor and one race is affixed to the housing and the other race is affixed to the rotor. A plurality of jet orifices for directing a jet of high-pressure fluid into the space between the apposed surfaces of the rotor and the housing are oriented so that at least a portion of the jet impinges on the roughened surface of the rotor at an acute angle. The apposed surfaces can be planar annuli or cylindrical annuli.
