PURPOSE:To prevent abnormal vibration at the time of high-speed rotation by using a rotary valve having a rotary shaft equipped in parallel with the crank shaft. CONSTITUTION:An intake 4 and an exhaust 6 groove are provided in a rotary body 1 having a rotary shaft installed in parallel with the crank shaft. The combustion chamber 8 at the cylinder head is provided with an intake 5 and an exhaust 7 hole to perform intake and exhaust of gas mixture. When the rotary body 1 rotates counterclockwise, the intake groove 4 passing the intake port 5 will permit the gas mixture A to flow into the combustion chamber 8 from the intake port 5 through intake groove 4. After explosion by the compression, the exhaust gas B is discharged from exhaust port 7 through exhaust groove 6. Thus abnormal vibration at the time of high-speed rotation is prevented. |
