プ。[Claims for Utility Model Registration] A timer piston that is arranged to be movable in the axial direction and controls the fuel injection timing in relation to the axial position; Fuel for a diesel engine, comprising a low pressure chamber to which fuel pressure on the suction side is transmitted, and a high pressure chamber provided on the other side of the timer piston and to which fuel pressure on the discharge side of a feed pump is transmitted via a high pressure side passage. In the injection pump, a first throttle provided in the high-pressure side passage, an opening/closing member that opens the high-pressure side passage when the fuel pressure on the discharge side of the feed pump increases, and an opening/closing member having a smaller diameter than the first throttle. A fuel injection pump for a diesel engine, characterized in that the second throttle is formed as a through hole.
