ROTARY ENGINE WITH INERTIA FORCES COMPENSATING SYSTEM (VERSIONS) Russian patent published in 1999 - IPC

FIELD: mechanical engineering; pumps, compressors and internal combustion engines. SUBSTANCE: engine has carrier with output shaft, ring-shaped working chamber and two pairs of blade pistons rigidly secured on two concentrically mounted shafts provided with levers transmitting rotation to eccentric shafts through connecting rods. Eccentric shafts are provided with planetary gear wheels which are in meshing with central fixed gear wheel. Each lever is installed relative to pistons with angle of displacement from 0 to 90 degrees, one in clockwise direction, the other, in counter-clockwise direction. Engine can be furnished with inertia forces compensating system consisting of weights able to displace radially. These weights are connected to levers by means of additional connecting rods. Levers are installed for rocking relative to each other. EFFECT: improved weight and size characteristics, reduced fuel consumption and toxicity of exhaust gases, increased service life. 3 cl, 6 dwg
