ROTARY MACHINE Russian patent published in 1997 - IPC

FIELD: mechanical engineering; pumps and engines. SUBSTANCE: rotor and stator ring in proposed rotary machine have common rotary supports. For this purpose cylindrical paths are made at both ends of stator ring in inner space and on outer side of rotor. At least three pairs of rollers are installed in side covers of housing in special holders. Roller are installed for mechanical closure with running paths of stator ring and rotor. Axes of rollers lie on line intersecting stator ring and rotor center line on section connecting the centers. Active rollers which are in contact with paths of stator ring are shaped to two diameters. Roller engages with path of stator ring over its larger diameter and with idler through its smaller diameter. Ratio of active roller diameters is equal to ratio of diameters of paths of stator ring and rotor. EFFECT: enlarged operating capabilities. 6 cl, 4 dwg
