FIELD: mechanical engineering. SUBSTANCE: opposite cylinders 2 are provided with movable bushings 3 interconnected, e.g. through rod 23 and provided with heads 4 and bottoms 5 coupled with the cylinders. Pistons 6 are received in bushings 3 between heads 4 and bottoms 5 to define under-piston chamber 8 and working chamber 9 of alternative volume and interconnected through rod 7. Pistons 6 and bushings 3 are mounted for permitting movement in opposite directions and coupled with levers 10 and 14 respectively. The levers convert reciprocation of the working members into rotation of crank shaft 18. EFFECT: enhanced reliability. cl, dwg
