る燃料噴射ポンプ。 a plunger that rotates and reciprocates in synchronization with the rotation of the engine; a pressurizing chamber that sucks fuel in a low pressure chamber by moving the plunger in one direction and pressurizes the intake fuel by moving the plunger in the other direction; In the fuel injection pump, the fuel injection pump includes a first electromagnetic valve that is operated during the movement of the plunger in the other direction to selectively discharge fuel in the pressurizing chamber to the low pressure chamber and control fuel injection. A second oil passage that communicates the pressurizing chamber and the low pressure chamber, an orifice that is provided in the second oil passage and limits the area of the passage, and an orifice that opens during the fuel pressurization stroke to communicate with the second oil passage. A fuel injection pump characterized by comprising a second solenoid valve for relief that opens a passage.
