Solenoid valve and fuel injector using same

A solenoid valve is provided which may be used to inject fuel into an internal combustion engine for automotive vehicles. The solenoid valve is designed to keep an air gap between a stator and an armature at a constant interval required to ensure a normal operation of the solenoid valve. The solenoid valve includes a spacer which is provided between the stator and the armature to keep the air gap without any hit of the armature on the stator. In one embodiment, the spacer is installed on a peripheral portion of the stator or the armature.
