PURPOSE:To reduce the size and weight of the device and increase the speed thereof by a method wherein a crank mechanism is not employed in the power converting device applied to an internal-combustion engine or the like and a rotor, provided with a plurality of cylinders and a wavy guide groove, is connected to the power converting device to permit the mutual conversion of reciprocating motion and rotary motion. CONSTITUTION:A roller 7, guided by the guide groove 3 by the rotation of a rotor 1, is lowered along the wavy configuration under being controlled in the peripheral movement thereof by the recessed groove 11 of a pushing member 9. A piston 5 is lowered through a connecting rod 6 in accordance with the lowering of the roller 7 and air is induced into a cylinder 4 through a suction valve. Subsequently, the piston 5 is elevated along the guide groove 3, ignition and explosion are caused at the upper dead point and the piston 5 is 3 pushed down. The push-down force is delivered to the wavy guide groove from the roller 7 and the rotary shaft 2 rotates through the rotor 1. Such motions are effected with time lags and the rotor 1 is rotated smoothly. |
