リ型気化器。[Claims for Utility Model Registration] A positioner that detects the position of a sliding valve, and an electric fuel that controls the flow rate of fuel to be supplied to a fuel passage in accordance with the measured air flow rate based on the detection signal from the positioner. Disposed between the flow rate control means and a negative pressure passage whose one end is connected to the fuel passage downstream of the electric fuel flow rate control means and whose other end opens to a bench lily portion whose cross-sectional area is changed by the slide valve. and an electric fuel flow rate sensor that controls the fuel flow rate in the fuel passage so that the pressure difference between the fuel pressure downstream of the electric fuel flow control means and the vent lily portion is constant based on the output signal of the level sensor. A variable bench lily type carburetor with control means.

Claims

[Scope of utility model registration request]

a positioner that detects the position of the slide valve; a solenoid valve that controls the flow rate of fuel to be supplied to the fuel passage according to the measured air flow rate based on the detection signal from the positioner; and one end downstream of the solenoid valve. A level sensor is installed in the middle of a negative pressure passage that is connected to the fuel passage and whose other end opens to the bench lily whose cross-sectional area is changed by the sliding valve, and the solenoid valve is controlled by the output signal of this level sensor. A variable vent lily type carburetor comprising a solenoid valve that controls the fuel flow rate in the fuel passage so that the pressure difference between the downstream fuel pressure and the vent lily portion is constant.
