型燃料噴射ポンプ。 It has a rotor housing, and a rotor that is rotated in the housing in synchronization with the rotation of the engine and has a plunger built therein that performs suction and discharge operations in accordance with the rotation of the rotor. When the fuel inlet hole and the intake port provided on the rotor communicate with each other, the metered fuel is sucked in. Distribution ports provided on the rotor are provided radially on the rotor housing to distribute the fuel to each cylinder of the engine. The distribution fuel injection pump is configured to forcefully deliver the fuel from the discharge passage to the fuel injection nozzle of the cylinder concerned when communicating with one of a plurality of fuel discharge passages leading to the injection nozzles, the rotor A distribution type fuel injection pump characterized in that a pressure equalization port is provided for communicating a plurality of passages outside the discharge stroke of each fuel discharge passage.
