摘要： A fuel injection valve has a valve body for opening and closing a valve seat, and receives an operation signal from a control unit to operate the valve body so that fuel is injected from a plurality of injection holes formed in an injection hole plate welded through a welded portion to a downstream side of the valve seat while passing through a gap between the valve body and the valve seat. The injection hole plate is formed at its central portion with a convex portion which is substantially axisymmetric with respect to a valve seat axis and which has a circular-arc shaped cross section, and the welded portion is also substantially axisymmetric with respect to the valve seat axis. Inlet portions of the injection holes are disposed in an injection hole arrangement surface diametrically outside of the convex portion and diametrically inside of a valve seat opening inner wall which is a minimum inside diameter of the valve seat, and the injection hole arrangement surface is coplanar with a surface having the welded portion.

摘要： A fuel injection valve includes a solenoid device which generates a magnetic sucking force; a core provided inside the solenoid device; a movable valve element composed of an armature coming into contact with the core, a pipe section whose one end is joined to the armature, and a valve section joined to the other end of the pipe section, the valve element being suctioned against a spring during energization of the solenoid device; and a valve seat unit having a valve seat to or from which the valve element is mounted or removed by the magnetic sucking force generated from the solenoid device and pressing force of the spring. The armature, the valve section, and the pipe section of the valve element are integrally configured by molding with resin, the armature and the valve section being joined by the pipe section.
