る燃焼器用噴射弁。An inner air introduction passage is formed facing the axis of the combustion chamber, and an inner peripheral wall is provided on the upstream side of the injection hole on the downstream side of the inner air introduction passage, and fuel is supplied as a swirling flow along the inner peripheral wall. The inner diameter of the fuel supply port is successively reduced from the fuel supply port to the injection hole on the downstream side, and the fuel flowing along the inner peripheral wall is thinned and uniformly guided. It has a guide part that performs primary fuel atomization, and an outer injection port that is provided on the outside of the injection hole and allows air to flow along the atomized fuel that is injected from the injection hole together with the combustion air. and an outer air introduction passage for performing secondary fuel atomization at the injection port.
