ンチユリ気化器。 The intake piston 4 projects into the intake passage 2 to form a bench lily part 5, and the main nozzle 15 and low-speed ports 18, 19 open to the intake passage 2 at the side of the bench lily part 5 and the throttle valve 20. In the variable bench lily carburetor, an atmospheric air introduction passage 21 is connected to a suction chamber 11 into which the negative pressure of the bench lily portion 5 is introduced to operate the intake piston 4 in the direction of increasing the cross-sectional area of the bench lily. An on-off valve 22 that opens and closes 21
The on-off valve 22 is configured to open when the negative pressure at a location downstream of the throttle valve 20 in the intake passage 2 and close to the throttle valve 20 is high, and to close when the negative pressure is low. A variable bench lily vaporizer characterized by:
