燃料供給装置。[Scope of Claim for Utility Model Registration] A pressure accumulator that maintains the pressure of starting fuel is connected to the discharge port side of the suction type primer pump that communicates with the metering chamber of the diaphragm carburetor, and the pressure accumulator is connected to the intake negative pressure port of the intake passage. The actuator is connected to a fuel nozzle disposed on the inlet side of the carburetor through a fuel release valve that communicates with and opens, and is connected to an actuator connected to a control member that opens and shuts off the jetting direction of the fuel nozzle. It communicates with the negative pressure port and also communicates with the atmosphere port via a heat-sensitive on-off valve, where the thermal ferrite, which recovers its magnetism below a predetermined temperature of the engine, resists the force of the spring and becomes a permanent magnet. A starting fuel supply device for a portable working machine engine, characterized in that the air is sucked in and closes the air port.
