Titre
(EN) Fuel injection valve
Abrégé
(EN)

An fuel injection valve has: a needle housed in a valve body in a reciprocable manner; an injection hole plate attached to a front end portion of the valve body, the plate having an injection hole connecting an inside and an outside of the valve body; and a valve sheet which the needle is attached to or detached from so as to close or open a fuel flow path that reaches the injection hole of the injection hole plate through an outer circumference of the needle. The injection hole plate has a recessed portion dented in an axial direction of the needle so as to cause fuel flowing toward the injection hole through the valve sheet to descend lower than a height of an inlet port of the injection hole and then, to turn to ascension so as to reach the inlet port of the injection hole on the injection hole plate.
