Claims

[Scope of Claim for Utility Model Registration] 1. A detection port whose positional relationship with respect to the throttle valve in the intake passage is reversed when the throttle valve opens beyond a predetermined opening degree, and a main air jet that introduces air into the emulsion pipe provided in the main passage. , a main air jet on-off valve that opens and closes this main air jet, a control valve device that is installed upstream of the emulsion pipe and controls the fuel flow cross-sectional area of the main passage, and a control valve that responds to the air pressure guided through the detection port. A carburetor comprising an actuator device that controls the operation of a main air jet on-off valve and a control valve device by interlocking a diaphragm. 2. Utility model registration claim 1, characterized in that the control valve device is an auxiliary jet opening/closing valve that opens and closes an auxiliary fuel jet provided in parallel with the main fuel jet (7). Vaporizer described in section. 3. The carburetor according to claim 1, wherein the control valve device is a tapered needle valve that controls the flow cross-sectional area of the fuel main jet.
