DRUM-TYPE ENGINE WITH SLEEVE GAS DISTRIBUTION AND CONTROLLED PHASES Russian patent published in 1994 - IPC

FIELD: engine engineering. SUBSTANCE: engine has fixed case 1, cylinders 2 which are set on the case parallel to crankshaft 3, movable sleeves 5 which moves within cylinders 2 over a part of screw line, driving mechanism with rocking washer 9, and mechanism for driving the sleeves. The last consists of pinion 16 provided on shaft 3 which engages with one of pinion 17 of intermediate shaft 18 whose second pinion 19 engages with first toothing 23 of double-toothing gear wheel 24 mounted coaxially to crankshaft 3 within the case of the engine. The second (conical) toothing 25 of double-toothing wheel 24 engages with all conical wheels 26 secured to cranks 14 of the drive of sleeves 5 which are kinematically connected to movable sleeves 5 and mounted within the case of the engine. Intermediate rollers 18 are movably mounted on carrier 20 which are coaxial to crankshaft 3 set in rotation about the axis of the shaft by a unit made of worm wheel 21 secured to the carrier and worm 22 secured to the case.
