ABSTRACT:
A fuel injection pump for an internal combustion engine wherein a plunger is mounted in a barrel for sliding axial movement and rotation about its own axis, and the barrel is formed therein with a suction port and an outlet port. A metering groove is formed in the plunger and maintained in communication with a top of the plunger through a bore formed in the plunger, so that a desired amount of metered fuel can be delivered to the engine according to the load applied to the engine by varying the area and the time at which the metering groove is brought into communication with the outlet port, thereby varying the amount of fuel outflow. A pulsation control chamber of a greater sectional area is formed in the fuel passageway between a discharge valve of the pump and a fuel valve so as to intensify and prolong the duration of throbs of a pulsating current of fuel moved through the pulsation control chamber as it is delivered by pumping.
