ンプユThe valve body of the fuel cutoff electromagnetic valve of the fuel injection pump includes a first valve body that opens and closes a passage communicating between the pump chamber and the pressure-feeding chamber, and a fuel bleed passage formed inside the first valve body that opens and closes the valve body. The fuel is characterized in that the second valve body has a double valve body structure, and the pressure receiving area of the second valve body from the forced indoor fuel at the time of fuel cutoff is smaller than the pressure receiving area of the first valve body. injection pump
