とを特徴とする燃料噴射弁。A fuel injection valve in which a needle valve rises and opens in response to fuel oil pressure in a first fuel reservoir formed by a first annular groove provided in the nozzle body and a needle valve. A second fuel reservoir is provided which is formed by the second annular groove and the needle valve and is supplied with fuel oil pressure-fed from the fuel injection pump. When the first oil passage that communicates with the fuel reservoir and the needle valve have a predetermined lift or more, the second fuel reservoir and the first fuel reservoir are communicated with each other, and the cross-sectional area is larger than the cross-sectional area of the first oil passage. A fuel injection valve characterized in that a needle valve is provided with a second oil passage having a second oil passage.
