Claims

[Scope of utility model registration request]

a plunger that is slidably attached to the plunger flock in the axial direction to form one node; a sleeve that can be fitted onto the plunger to cover the lead of the plunger; The plunger is provided with a plunger drive mechanism that can be firmly moved in the axial direction, and the plunger has a communication hole that communicates the lead with a compression chamber at the end of the plunger, and a communication hole that is exposed from the sleeve near the end of compression of the plunger. The plunger is provided with a spill boat and a communication path that communicates the spill boat with the communication hole portion, and has an annular i-bay portion in the peripheral portion of the plunger including the spill port in order to improve the cut-off of the injection at the end of compression of the plunger. A fuel injection pump characterized by the following:
