に備えられた負圧通路の途中に、所定の作動負圧
を供給するための負圧供給手段を接続し、その接
続位置に、潤滑油及び冷却水の温度が設定値以上
になつたときに通路を負圧供給側に切り換える切
換弁を設けたことを特徴とする燃料噴射装置。 A negative pressure supply means for supplying a predetermined operating negative pressure is connected in the middle of the negative pressure passage provided in the correction device that reduces the fuel injection amount at low atmospheric pressure, and lubricating oil and cooling are connected to the negative pressure passage. A fuel injection device characterized by being provided with a switching valve that switches a passage to a negative pressure supply side when the temperature of water exceeds a set value.
