ことを特徴とするデイーゼルエンジン用燃料噴射
ノズル。 A fuel reservoir formed in the nozzle body to which fuel is guided, a first nozzle hole bored at the tip of the nozzle body, and a second nozzle hole drilled further toward the tip side of the nozzle body from the first nozzle hole. a first needle valve disposed movably in the axial direction within the nozzle body and biased in an opening direction by fuel pressure in the fuel reservoir to control communication between the fuel reservoir and the first jet orifice; , disposed coaxially inside the first needle valve so that the first needle valve can move relative to each other on an outer periphery of the fuel reservoir and the second injection port when the first needle valve is opened; a second needle valve that controls communication with the nozzle body; a first stopper that restricts relative movement of the first needle valve in the opening direction with respect to the second needle valve; and a first stopper that restricts the relative movement of the first needle valve with respect to the second needle valve in the opening direction; a second stopper that limits relative movement of the valve; a first spring that biases the first needle valve in the closing direction; and a second spring that has a biasing force greater than the first spring and closes the second spring. 1. A fuel injection nozzle for a diesel engine, comprising a second spring biasing the fuel injection nozzle in the direction of the fuel injection nozzle.
