ABSTRACT:
A fuel injection valve includes a valve body having a valve seat, a nozzle plate arranged on an injection side of the valve body, a valve plug for intermitting fuel injection through the nozzle hole, and a sleeve. The nozzle plate has a nozzle hole through which fuel is injected from the injection side of the valve body. The sleeve makes contact with an end surface of the nozzle plate on an opposite side of the valve body with respect to the nozzle plate to partially cover the nozzle plate. Fuel is injected to an outside of the sleeve through the nozzle hole of the nozzle plate and an opening of the sleeve. The end surface of the nozzle plate makes contact with the sleeve in a contact portion. The contact portion has at least one groove that extends from the opening outwardly with respect to a substantially radial direction of the sleeve.
