噴射ポンプ。A double plunger type fuel injection pump comprising a first plunger that sets the amount of fuel to be injected and performs injection, and a second plunger that is fitted onto the first plunger and adjusts the injection start timing. A lubricating oil supply groove is formed on the inner circumferential surface of the plunger barrel that accommodates each of the second plungers at an appropriate location below the fuel ash draining groove provided on the inner circumferential surface, and one end of the lubricating oil supply groove is formed in the wall at an appropriate location below the fuel ash draining groove provided on the inner circumferential surface. The second plunger is aligned with the lubricating oil supply groove at a predetermined lift position, forming a passage that opens into the oil supply groove, the other end opens at an appropriate location on the outer circumferential surface, and is connected to the lubricating oil supply system. 1. A dual plunger type fuel injection pump, characterized in that at least one through hole is bored in the first plunger, and a lubricating oil groove is formed on the outer circumferential surface of the first plunger to align with the through hole of the second plunger.
