ンチュリ型気化器。Located in the middle of the intake passage, upstream of the throttle valve,
A venturi fixing part having an open nozzle part for introducing fuel from a float chamber, and a suction piston slidably housed in a suction cylinder opposite to this fixing part are provided, and the fixing part and the suction piston are connected to each other. A variable venturi portion is formed between the small diameter portion and the bottom surface, the suction piston is provided with a jet needle passing through the nozzle portion, and a negative chamber and an atmospheric chamber are defined between the suction piston and the negative pressure. Venturi negative pressure is introduced into the chamber through a spring that biases the suction piston toward the venturi fixed part and a suction hole formed in the suction piston so as to open facing the variable venturi part, thereby increasing the intake flow rate. Alternatively, in a carburetor in which the suction piston retracts against the spring to enlarge the variable venturi portion as the venturi negative pressure increases, the sliding portion of the suction piston in sliding contact with the suction cylinder is on the atmospheric chamber side. 1. A variable venturi type carburetor, characterized in that the flange is formed by folding back and the flange overlaps a sliding surface of a small diameter portion of a piston.
