Zusammenfassung: | A fuel injection valve includes housing (10), a fixed core (21), a movable core (22), a valve member (40) and a coil, a fuel passage (6) is formed in the housing. The movable core and the valve member are different members, and the valve member is arranged in a throughhole (220) formed on the inner side of the movable core slidely. An end face of the movable core on the side of the fixed core hasa contact surface (231) attracted by the fixed core and contacting with the fixed core, and a non-contact surface (232) without contact with the fixed core. The non-contact surface and the stator define a space. The fuel injection valve has a movable core communicating passage (25), for communicating the fuel passage (6) locating on the downstream side of the movable core, and the space. |
