PURPOSE:To simultaneously attain excess fuel operation in accordance with a supercharge and fuel reducing operation in the highland with a single device, by interposing a diaphragm to neighbor a supercharge pressure chamber and an atmospheric pressure chamber and providing a bellows connected to the diaphragm through a spring in the atmospheric pressure chamber. CONSTITUTION:If supercharge pressure applied to a supercharge pressure chamber 5 is increased, a diaphragm 6 is pressed downward against a spring 9 to move a push rod 11 downward and increase an injection amount. While if the atmospheric pressure decreases on the highland, a bellows 12 is expanded to compress the spring 9, and the rod 11 is moved upward to a position, in which a load of the spring 9 and pressure applied to the diaphragm 6 are balanced, to decrease the injection amount. |
