められることを特徴とする燃料供給装置。 The slow system and main system are configured to 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, and the fuel passage is shared. In a fuel supply device configured to control the fuel flow rate of both systems by a solenoid valve disposed in the middle thereof, a slow system transient control passage opens downstream of a main jet and bypasses a pilot jet. and a main system transient control passage that bypasses the main jet are switched by a single switching valve, and the fuel flow rate of both passages is controlled by a single transient control solenoid valve. Feeding device.
