燃料噴射装置の加速チヤンバー。[Claim for Utility Model Registration] A negative pressure diaphragm to which negative pressure is applied according to the air flow rate, and a volume of a downstream chamber is increased or decreased in conjunction with the negative pressure diaphragm to control the amount of fuel discharged from the downstream chamber. In a pressure-balanced fuel injection device having slow system and main system fuel metering means each having a fuel diaphragm, a fuel storage chamber communicating with the downstream chambers of each of the slow system and main system fuel metering means is connected to the diaphragm. A fuel characterized by comprising an acceleration chamber partitioned by an acceleration chamber that displaces the diaphragm in conjunction with an increase or decrease in the opening degree of the throttle valve to decrease or increase the volume of the storage chamber. Acceleration chamber of the injector.
