PURPOSE:To permit high-speed operation and reduce noise by allowing the gears having air vents to be revolved between a cylinder and a cylinder head and constituting rotary-type intake and exhaust valves. CONSTITUTION:Gears 3 having an air vent are installed between a cylinder and a cylinder head through each rolling body 1 and meshed with each other. Said gear 3 are revolved in synchronization with the revolution of an engine by allowing one gear to be driven by the other gear 2 driven by a crankshaft. An intake valve and an exhaust valve are constituted so that the intake port and the exhaust port are opened and closed trough the air hole of the gear 3. Therefore, the valve can be constituted in rotary type, and high-speed operation is permitted, and the generation of noise can be reduced. |
