|1. (WO2018083795) FUEL INJECTION VALVE|
|Applicants:||MITSUBISHI ELECTRIC CORPORATION
|Title:||FUEL INJECTION VALVE|
Provided is a fuel injection valve wherein a valve body has a cylindrical armature facing a core, and also has a valve body main body affixed to the armature. The valve body main body is brought into contact with a seat surface when the armature is displaced in the direction away from the core, and the valve body main body is moved away from the seat surface when the armature is displaced in the direction toward the core. The core-side end of the armature is provided with a protrusion and a flat surface-forming section which is located radially outside the protrusion. The flat surface-forming section has a first perpendicular flat surface section continuous from the protrusion. The first perpendicular flat surface section is parallel to a plane perpendicular to the axis of the armature. The protrusion protrudes further toward the core than the position of the first perpendicular flat surface section. The outline of the protrusion in a plane including the axis of the armature consists of an arc-like curved line continuous from the inner peripheral surface of the armature.
