Claims

[Claims for Utility Model Registration] Fuel can be pumped by reciprocating a plunger 3 within a barrel 2 attached to the pump body 1, while an annular valve 6 is slidable and rotatable on the outside of the plunger 3. The annular valve 6 and the plunger 2 are rotated relative to each other by an appropriate metering actuator 70, and the plunger 2
By changing the communication timing between the lead 46 formed in the annular valve 6 and the spill hole 45 formed in the annular valve 6, the amount of fuel pumped is controlled, and an appropriate injection timing adjustment actuator 7
1 controls the fuel injection timing by displacing the annular valve 6 in the axial direction of the plunger 2, and further distributes the fuel pressurized by the plunger 3 to a plurality of sources on the engine main body side by an appropriate distribution mechanism W. This distribution type fuel injection pump for an internal combustion engine is configured to sequentially supply fuel to each of the fuel injection valves provided in the pump body 1, and the pump body 1 is configured to be displaced in accordance with an electrical signal transmitted according to the load condition of the engine. The metering device section (1), which has a near solenoid 24 that drives the metering actuator 70, changes according to an electrical signal transmitted in response to fluctuations in the rotational speed of the engine. a timer unit V having a near solenoid 25 for driving the injection timing adjusting actuator 71; A distribution type fuel injection pump for an internal combustion engine, characterized in that: and are directly attached to each other.
