エアバルブ式気化器。An air valve whose opening and closing are controlled by the intake air flow is provided in the intake passage of the secondary side carburetor, an accelerating fuel well is formed on the side of the intake passage of the secondary side carburetor, and the well is connected through a throttle. A pick-up tube for supplying accelerated fuel is connected to the float chamber of the carburetor and extends substantially vertically into the well, and a fuel inlet of the tube is opened into the fuel in the well, and the fuel in the pick-up tube is connected to the float chamber of the carburetor. In an air valve type carburetor having an outlet opening in the intake passage between the air valve and the secondary throttle valve, a switching piston connected to the air valve is inserted into the upper space of the well, and the switching action of the piston is controlled. When the air valve is below a predetermined opening, negative pressure in the intake passage downstream of the air valve is applied onto the fuel liquid level in the well, and when the air valve is above the preset opening, the negative pressure is applied above the fuel liquid level in the well. An air valve type vaporizer that applies atmospheric pressure to the air.
