Abstract
A fluid-powered rotary motor, and method of operating the same. Pressured fluid is introduced to the annular clearance between a rotor and a second member, and reaches an outlet by travelling circumferentially within that clearance. The direction of motion of the fluid on entering the clearance is substantially tangential relative to the rotor, so as to avoid any substantial jet impingement of the fluid upon the rotor, and so that the rotor is driven substantially wholly by the hydrodynamic viscous drag action of the fluid upon it. Methods of profiling the rotor surface are disclosed which enhance the surface area over which the viscous drag action can be effected.
