プ。[Claims for Utility Model Registration] A plunger is disposed in a plunger barrel and performs reciprocating and rotational motion, and a large number of suction grooves are formed at equal angular intervals at the tip of the plunger, and one of the suction groups is The plunger has a distribution port that sequentially matches suction ports formed in the plunger barrel to receive fuel supply, and that communicates with a pump chamber whose volume is changed by reciprocating movement of the plunger and a communicating inner hole. In the distribution type fuel injection pump, the distribution port is sequentially connected to discharge passages formed according to the number of engine cylinders to distribute fuel as the plunger rotates. A distribution type fuel injection pump characterized in that the vertical length is approximately twice the horizontal length, and the suction slit is lengthened accordingly.
