プ。 It has a feed pump that feeds fuel from the fuel tank into the pump, and a hydraulic timer that controls fuel injection timing, and the suction side pressure of the feed pump is applied to one side of the timer piston of the timer, and the pump internal pressure is applied to the timer piston. In a distribution type fuel injection pump that is led to the other side, the fuel passage that communicates with the pump and can regulate the internal pressure of the pump by releasing the fuel inside the pump is caused by the inertia force acting on itself or the vehicle's own weight. 1. A fuel injection pump characterized in that a pressure regulating valve having a valve body movable in a direction is arranged such that a direction in which the valve body moves toward the rear of a vehicle is a direction that closes the fuel passage.
