装置。 A control rack 1 for controlling the injection amount is connected to a piston rod 3 of a power cylinder 2, and a spool valve 5 controls the supply of pressure oil discharged from a pump 10 to the power cylinder 2.
In this fuel injection device, the return spring 4 is provided in the reduction chamber 2b of the power cylinder, and the return spring 4 is provided in the reduction chamber 2b of the power cylinder, and the return spring 4 is moved by the centrifugal force of the spring 8 and the flyweight 7, whose installation load is set by the control lever 12. This oil pressure is transferred to the spool valve 5.
A fuel injection device for a diesel engine, characterized in that feedback pressure is applied to the lower end of the engine.
