INTERNAL COMBUSTION ENGINE Russian patent published in 1997 - IPC

FIELD: engine engineering. SUBSTANCE: cylinder provided with vanes secured to its inner side is rigidly connected with a gear with inner teeth. Gears-eccentrics that engage the fixed gear coaxial to the cylinder and cover which is mounted on the slots of the output shaft. Inside the cylinder is a hollow shaft mounted coaxially to the cylinder and output shaft provided with vanes and gear which coupled with the gear with the inner teeth of the gear the axles of which is coupled with the eccentric portions of the gear- eccentrics through ties. The gear-eccentrics roll over the fixed gear which move the gears on axles when the cylinder is set in rotation with the ties. The axles roll over the gear with inner teeth and periodically rotate the gear of the hollow shaft with vanes with respect to the cylinder at a given sites of the cylinder. During the combustion stroke the torque is transmitted from the cylinder vanes immediately to the output shaft. EFFECT: enhanced efficiency. 2 cl, 5 dwg
