Claims

[Scope of Claim for Utility Model Registration] A mixture suction hole 4 and an air supply hole 5 are provided in the crank chamber 2, and the air supply hole is connected to the intake port 3 of the combustion chamber 1 via an air supply pipe 6, so that the operation of the piston 7 In a four-stroke model engine that is equipped with a valve body 8 that opens and closes the suction hole and the air supply hole according to the requirements, and that pumps the air-fuel mixture into the combustion chamber 1 by the pumping action of the piston, a control valve is installed in the middle of the air supply pipe 6. A mixture intake amount control device for a four-stroke model engine, characterized in that a throttle valve 9 is provided in the carburetor 10 or in the vicinity of the carburetor 10, and the throttle valve 11 is opened and closed at the same time. Claim 1 describes the utility model registration in which the air supply pipe 6 and the carburetor 10 are arranged side by side, and the control valve 9 and the throttle valve 11 are provided on the same rotating shaft 12 so that they can be opened and closed at the same time. Air-fuel mixture intake amount control device for a 4-stroke model engine.
