料噴射ポンプのロードタイマ。 An injection timing adjustment device that is controlled by the fuel pressure generated in the pump chamber depending on the engine speed, and a radial control device formed on the governor sleeve that is fitted onto the governor shaft and pushed by a flyweight. a hole, an annular groove formed on the outer periphery of the governor shaft, and an oil return passage that opens into the annular groove formed inside the governor shaft and communicates the pump chamber with the suction side of the oil feed pump,
Loading of a distribution type fuel injection pump that releases fuel in the pump chamber to the suction side by matching the control hole and the annular groove, and controls the injection timing by adjusting the fuel pressure in the pump chamber according to the load. In the timer, a control piston that receives fuel pressure in the pump chamber and a spring that biases the control piston are provided inside the governor shaft, and the control piston controls communication between the annular groove and the oil return passage. A load timer for a distributed fuel injection pump that is characterized by:
