Claims

[Scope of utility model registration request]

The metering chamber facing the diaphragm and the external passage on the fuel tank side are connected by an inlet side passage, the metering chamber and the main jet are connected by an outlet side passage, and the overflow passage closed by an overflow valve is connected to the metering chamber. The overflow valve is connected to the overflow valve, a mechanism for opening the valve is provided, a starting pump is provided in the inlet side passage, a passage opening/closing part that is linked to the operating part of the starting pump is provided in the outlet side passage, and the above operation is performed. The passage opening/closing part is configured to close the outlet side passage when the part moves in the fuel pumping direction, and a return mechanism is provided to return the passage opening/closing part to a position where the outlet side passage is opened when the part is not operated. Membrane valve type vaporizer.
