めた可変ベンチユリ型気化器。 A variable vent lily type carburetor that is equipped with a negative pressure chamber and an atmospheric pressure chamber separated by a suction piston, and in which the suction piston changes the intake passage area based on the pressure difference between the negative pressure chamber and the atmospheric pressure chamber. When the lift amount of the suction piston is smaller than a predetermined lift amount, the suction piston is closed by the outer peripheral surface of the suction piston, and when the suction piston lift amount is larger than the predetermined lift amount, the suction piston is closed by the intake passage. A variable bench lily type carburetor having an open negative pressure port formed on an inner wall surface of an intake passage in sliding contact with an outer circumferential surface of a suction piston, and communicating the negative pressure port with the negative pressure chamber.
