Claims

[Scope of utility model registration request]

A plunger block, a Y plunger that is slidably attached to the plunger block in the axial direction and has a lead curved in the circumferential direction, and a discharge that can be fitted onto the plunger and aligned with the lead of the plunger. a sleeve having a hole formed therein; and a sleeve moving mechanism that is provided with a sleeve having a hole therein and a plunger drive mechanism capable of driving the plunger i in the axial direction, and that moves the sleeve in the axial direction in order to adjust the fuel injection timing; The guide groove of the sleeve is provided with a guide groove formed on the outer periphery of the sleeve and a knob that fits into the guide groove. A fuel injection pump, characterized in that the is formed in a direction intersecting the axial direction.
