。Fuel can be pumped by reciprocating the plunger 3 within the plunger insertion hole 28 of the barrel 2 housed in the pump body 1, while an annular valve 4 is relatively rotated and moved outside the plunger 3. The annular valve 4 is mounted so as to be slidable relative to the plunger 3 and rotated relative to the plunger 3 by an appropriate metering operation member 5, thereby forming a passageway extending over the top surface 3a, side surface 3b, and circumferential surface 3b of the plunger 3. Oil hole 1
3 and the oil escape hole 20 formed in the annular valve 4 is changed to control the fuel injection amount.
A timer pin 7 having an eccentric head 7b attached through a timer pin attachment hole 23 formed through a side wall 22 of the pump body 1 is appropriately adjusted by a timer adjustment rod 6 that moves forward and backward in the axial direction according to the rotational state of the engine. A fuel injection pump for an internal combustion engine, in which the timing of fuel injection can be adjusted by rotating the timer pin 7 to appropriately displace the annular valve 4 in the axial direction of the plunger. The internal combustion engine is characterized in that the rod 6 and the timer pin 7 are interconnected by an appropriate engagement device 32 having an annular projection 31 and a spherical projection receiving portion 34 for engaging the spherical projection 31. Engine fuel injection pump.
