FOUR-STROKE ROTARY-VANE TANGENTIAL ENGINE Russian patent published in 2003 - IPC

FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: according to invention, torque caused by combustion of fuel in rotor unit is transmitted by vanes of two rotors by means of two shafts, one nested in the other, to rotation integrator, summed up through bevel gears installed on shafts and coupled with planet pinions and is transmitted to power takeoff shaft in turn by gear wheels of ratchet mechanisms installed on said shafts. Simultaneously reactive torque from planet pinion axle arranged radially in flywheel rotating coaxially with rotors is transmitted to integrator. Order of operation of ratchet mechanisms is defined by centrifugal buffers and limiters installed on setting flanges secured on end faces of flywheel with possibility of angular displacement at adjustment and acting by control disks with stops on head of ratchet pawls. Invention makes it possible to get high efficiency at relatively small dimensions with large safety margin of rotation integrator owing to the fact that it is brought out of one of rotors to provide reliability and long service life. Engine can be made both for low and high compression ratios. EFFECT: simplified design of engine. 4 cl, 10 dwg
