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. The fuel flow rate of both systems is controlled by a solenoid valve disposed in the middle of the air valve, and the operation of an air valve that can block the intake passage in the slow region is controlled based on the negative pressure on the downstream side. In the fuel supply device, a plurality of negative pressure intake ports to the negative pressure chamber of the negative pressure actuator for the air valve are provided on the upstream and downstream sides of the air valve, so that the operating negative pressure on the downstream side of the air valve can be controlled. A fuel supply device characterized by:
