装置。 The fuel injection nozzle is provided with a fuel injection nozzle that opens toward the combustion chamber of the combustor, and a fuel supply passage communicating with the nozzle, and is supported within the fuel supply passage via a support member to adjust the passage area of the nozzle. A poppet valve is provided between the inner wall of the fuel supply passage and the poppet valve in order to change the passage area of the nozzle so as to achieve a fuel spray state according to the flow rate of fuel in the fuel supply passage. A fuel injection nozzle device for a combustor for an underwater vehicle, characterized in that a spring is interposed to bias a poppet valve in the closing direction.
