PD-T/3 ROTARY ENGINE Russian patent published in 2001 - IPC

FIELD: mechanical engineering; internal combustion engines with correction of displacer in working space. SUBSTANCE: proposed rotary engine has housing with side covers, working chamber located in housing, three-surfaced displacer, drive mechanism with eccentric corrector and shaft, valveless gas-exchange system, internal and external gears. Displacer is suspended from eccentric corrector through rotary supports, is rigidly connected with crossmember and output shaft and is arranged in elliptic working chamber. Rotary supports engage with elliptic surfaces of working chambers. Eccentric corrector is suspended from crankshaft through rotary support with possibility of opposite-direction rotation with gear ratio of 1:1. Displacer rotates relative to crankshaft at gear ratio of 1:3. EFFECT: increased service line, reduced manufacturing cost and fuel consumption, provision of compactness. 3 cl, 6 dwg
