御装置。 A feed pump that pumps fuel into a pump chamber; a plunger that is slidably disposed in a cylinder bore forming a variable pressure chamber and discharges fuel supplied from the pump chamber into the variable pressure chamber to a fuel injection nozzle; and a fuel attached to the plunger. A centrifugal force governor is connected to an injection control spill ring via a swingable control lever to move the spill ring, and a centrifugal governor is connected to a rotary drive shaft to transmit the rotation to a plunger and is locked to a roller-shaped cam follower. A cam plate that reciprocates the plunger in its axial direction by a predetermined cam lift, a timer piston that is connected to the roller and is displaced according to the pressure in the pump chamber to change the fixed position of the roller, and engine load and engine rotation speed. It has a load sensing timer that automatically controls the fuel injection timing by releasing the fuel pressure in the pump chamber according to In a fuel injection pump that discharges indoor fuel from a fuel injection nozzle, the load sensing timer is connected to the tip of a control lever, and includes a movable member that reciprocates in one direction according to the movement of the control lever, and a reciprocating motion of the movable member. a fixed member that guides the movement of the feed pump; a communication passage formed within the fixed member and connected to the suction side of the feed pump; 1. An injection control device for a fuel injection pump, comprising an opening that selectively communicates with a pump chamber depending on its relative position with respect to the pump chamber.
