る可変ベンチユリ気化器。 In a variable bench lily carburetor, in which the effective area of the vent lily changes depending on the intake air amount and the vent lily negative pressure is kept almost constant, there is a bleed air passage opened in the fuel passage on the downstream side of the main nozzle, and a A variable air bleed is provided with a measuring part provided in the middle, and the measuring part consists of a vertical tapered part that gradually becomes smaller in diameter toward the bottom and a floating body inserted into this tapered part, so that the negative pressure of the bench lily is high. The variable bench lily vaporizer is characterized in that the floating body rises to increase the amount of bleed air.
