Claims

[Scope of utility model registration request]

Fuel can be pumped by reciprocating the plunger 33 within the barrel 31, while an annular valve 35 is fitted on the outside of the plunger 33, and the annular valve 35 and the plunger 33 are connected to an appropriate metering operation member. The annular valve 35 is controlled by an appropriate timer operating member 79 by relatively rotating the annular valve 37 to change the opening/closing timing of the oil hole 40 communicating with the top surface 33a of the plunger 33. This fuel injection device has a fuel injection pump X that can control the fuel injection timing by displacing it in the axial direction by the metering operation member 37. A metering control mechanism (1) having a metering solenoid 21 that is displaced by a signal, and a timer solenoid 22 that is displaced by an electrical signal transmitted to the timer operating member 79 according to the rotational state of the engine. Control mechanism W
A fuel injection device characterized in that the metering control mechanism V can control the amount of fuel to be injected, and the timer control mechanism W can control the injection timing.
