とを特徴とする燃料噴射ノズル。a nozzle body having a nozzle hole, a needle valve housed between the nozzle body and capable of freely opening and closing the nozzle hole, and a stopper mechanism that elastically presses the needle valve toward the nozzle hole closing side;
A pressurizing chamber is provided which communicates with the nozzle hole and pressurizes the needle valve with fuel introduced from the fuel injection pump, and when the fuel pressure exceeds the elasticity of the stopper mechanism, the nozzle hole is opened and fuel is injected. A fuel injection nozzle characterized in that the fuel injection nozzle is equipped with a pressure control mechanism that uses hydraulic pressure to adjust the elastic urging force of the stopper mechanism against the needle valve and adjusts the opening pressure of the needle valve.
