Claims

[Scope of Claim for Utility Model Registration] (1) It has an inner vent turret and an outer vent lily in the middle of the intake passage, the main nozzle for injecting the main fuel is opened in the inner vent lily, and one part of the wall of the outer vent lily is opened. A piston valve that is displaced by negative pressure in the intake passage opens a power nozzle that injects power fuel into the outer vent lily, and injects power fuel from the power nozzle to the outer vent lily according to the displacement of the piston valve. In a variable ventilee type carburetor, a slidable metering member for adjusting the amount of power fuel in the nozzle pipe of the power nozzle;
a spring for pressing the metering member toward the piston valve, and a metering throat projecting inwardly formed on the inner wall of the nozzle pipe. (2) The variable ventilee type carburetor according to claim 1, wherein the metering member is a needle having an outer diameter that differs in the longitudinal direction. (3) The variable ventilator according to claim 1, wherein the metering member is a pipe that slides into contact with the metering throat, and the pipe is formed with a fuel passage hole that communicates with the inside and outside. type vaporizer.
