(54) FUEL INJECTION VALVE


(57) A fuel injection valve includes a nozzle body that includes a suction chamber in its tip portion and an injection aperture opening into the suction chamber; a needle that is slidably located in the nozzle body, and forms a fuel introduction path to the suction chamber between the nozzle body and the needle; and a cylindrically-shaped control member that is positioned by a positioning portion located between an upper edge portion of the suction chamber and the injection aperture in the nozzle body, a position of the upstream edge portion shifting upstream so as to approach the needle when the needle lifts and fuel flows into the suction chamber. As the upstream edge portion approaches the needle, the gap between them remains narrow, and this continually generates cavitation and promotes atomization of the fuel.
