Claims

[Scope of utility model registration request]

A fuel jet installed in the fuel passage that communicates from the float or chamber to the venturi section of the intake passage, a suction piston that moves back and forth in a lateral direction with respect to the venturi section depending on the load condition of the internal combustion engine, and the outer periphery of the suction piston. a suction chamber having an inner wall surface on which slides;
an internal combustion engine having a metering needle whose base is attached to the bottom of the suction piston and which controls the jet area of the fuel jet by movement of its free end.
A variable venturi carburetor for use in a variable venturi carburetor, wherein the jet portion of the fuel jet is provided with at least two or more air bleed holes opened at approximately equal intervals on the inner circumference,
The metering needle has its base attached to a metering needle housing provided at the bottom of the suction piston such that the metering needle slides with the side surface of its free end in contact with one side of the inner circumference of the jet section. A variable venturi carburetor characterized by a rotatable mounting.
