とする燃料噴射ポンプ。 A plunger that rises to compress the fuel supplied into the plunger chamber, a discharge valve spring that biases the discharge valve in the closing direction, and a plunger that resists the discharge valve spring when the pressure inside the plunger chamber rises above a certain pressure. In a fuel injection pump, the fuel injection pump includes a discharge valve that rises to discharge fuel in the plunger chamber, and a discharge valve stopper that restricts the raised position of the discharge valve, and a cylindrical part that opens downward toward the discharge valve stopper. A fuel injection pump characterized in that a piston-shaped protrusion is provided at an upper part of the discharge valve to be inserted into the cylinder-shaped part.
