とを特徴とする燃料噴射ノズル。A nozzle body in which a fuel injection port is formed, a magnetic pole member excited by a solenoid coil, an armature that is attracted to the magnetic pole member, a valve that can open and close the fuel injection port in conjunction with the armature, and a valve. an elastic member that biases the fuel injection port to close; when the armature is attracted to the magnetic pole member, the valve lifts to open the fuel injection port, and fuel is injected from the fuel injection port. The nozzle is provided with a valve damper means for delaying the lift speed of the valve when the lift starts, and the valve damper means is a pressure chamber filled with a fluid that provides resistance to the attraction when the armature is attracted to the magnetic pole member. A fuel injection nozzle comprising: a piston that closes the pressure chamber; and a piston spring compressed within the pressure chamber.
