ポンプ。[Scope of claim for utility model registration] An injection timing adjustment device that is controlled by the fuel pressure generated in the pump chamber according to the engine speed, and a governor sleeve that is fitted onto the governor shaft and is actuated by a flyweight. a radial control hole formed, an annular groove formed on the outer periphery of the governor shaft, and an oil return 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. It consists of a passage,
A distribution type equipped with a load timer that releases the 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 fuel injection pump, the oil return passage includes a piston that opens and closes the passage, a spring that presses the piston in a direction against fuel pressure in the pump chamber, and a spring that changes the volume depending on temperature and displaces the position of the piston. A distribution type fuel injection pump characterized in that it is provided with a temperature-sensitive member.
