ツトル型燃料噴射ノズル。 The nozzle body includes a nozzle body and a needle valve movably provided inside the nozzle body, and a valve seat and a nozzle hole extending from the valve seat to the outer surface of the nozzle body are formed inside the nozzle body. The needle valve includes a valve part that seats and lifts with respect to the valve seat as the needle valve moves, and in a state where the valve part is seated on the valve seat, the nozzle hole has an annular gap. In a throttle-type fuel injection nozzle in which a throttle part is formed in which the nozzle fittings are fitted and the tip part penetrates the nozzle hole and protrudes to the outside, a protruding part is formed on the outer circumferential surface of the throttle part with an outer opening of the nozzle hole. A throttle type fuel injection nozzle characterized by being formed at approximately the same position.
