とを特徴とする燃料供給装置。 It has a slow system and a main system that can maintain an appropriate air-fuel ratio by controlling the fuel flow rate to maintain a constant liquid level in the negative pressure passage that communicates with the fuel passage leading to the fuel chamber. In a fuel supply device configured to supply fuel in a common fuel passage to a bench lily via an emulsion tube, the negative pressure passage and the emulsion tube are respectively communicated with an air vent via an air jet, and the An atmosphere release passage is provided to the air vent, and a passage leading from the air horn side end of the air vent to the canister side is branched, and a ball vent valve disposed at the end of the air vent connects the canister to the air vent. A fuel supply device characterized in that the negative pressure passage and the air jet of the emulsion tube and the atmosphere opening passage are cut off from the air horn side when the engine is stopped.
