ROTARY MACHINE Russian patent published in 2006 - IPC F01C1/63 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to displacement rotary machines and it can be used in compressors, pumps and internal combustion engines. Proposed rotary machine has two housings with end face partition, two end face covers and two end face hollow cylindrical covers, each provided with first covers. It has also side disks, output shaft, motion transforming mechanism with elliptical gears, turnable blades, intermediate shafts, cylindrical gears and second covers. Pair of hollow shafts with solid side disks is installed in each housing on bearings to which blades in diametrically symmetrical direction are rigidly connected and fixed by second covers, and two pairs of elliptical gears. Each pair is rigidly installed on ends of hollow shafts with disks from both sides of end face covers and it gets into meshing with other pair of elliptical gears rigidly installed on intermediate shafts in diametrically symmetrical directions on bearings between end face and hollow end face cylindrical covers. Cylindrical gear in meshing with similar pair of gears rigidly secured on ends of output shaft installed on bearings is rigidly secured on each intermediate shaft. Output shaft passes through hollow shafts with disks, end face partition end face and end face hollow cylindrical covers and is fixed by first covers.

EFFECT: elimination of inertia unbalancing at rotation of coaxial turnable blades.
