ROTARY MACHINE Russian patent published in 1998 - IPC

FIELD: compressors, pumps or internal combustion engines. SUBSTANCE: rotary machine includes hollow cylindrical housing with end covers. Inside cylinder blades are located with are provided with rollers. Blades divide cavity into four closed volumes. Synchronization mechanism made in form of shaft with monolithic cross-member is also located in cylinder Shafts with rollers fitted with eccentrics are inserted in blades via through holes. Cylindrical surfaces are profiled symmetrically in end covers in diametrically opposite directions at radius shifted vertically from center of rotation of blades in coordinate grid by magnitude of plus/minus eccentricity and radius shifted horizontally and symmetrically relative to center of rotation. EFFECT: enhanced reliability. 3 dwg
