PURPOSE:To disuse the valve mechanism of a rotary engine for simplifying the structure and reducing noises and vibrations by fitting a rotation member provided with a cylinder hole into a casing provided with cylindrical inside to be rotatable and inserting a piston into the cylinder hole to be freely slided. CONSTITUTION:A casing 1 with cylindrical inside 1-1 is provided with a suction port 2 and an exhaust port 3, and equipped with an ignition device 4. A rotation member 5 is contained in the casing 1 to be rotatable and closely fitted to the inner surface of the casing, and a piston 6 is fitted in a cylinder hole 5-1 provided radially in the member 5 to be freely slided. The piston 6 is held in the eccentric rotation part of a crankshaft 8 via an eccentric ring 7, and a gear 10 provided in the eccentric rotation part is engaged with an internal gear 9 of the casing 1. A gear 11 provided in the eccentric rotation part is engaged with an internal gear 12 of the rotation member 5, and thereby, when the crankshaft 8 is rotated thrice, the rotation member 5 is rotated once in the same direction. |
