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.

An annular passage communicating in a circumferential direction is defined between the inner peripheral surface of the valve main body and the outer peripheral surface of the guide portion and a fuel passage through which to introduce a fuel from the annular passage to the seat portion is defined. An almost cylindrical filter to trap foreign matter heading toward the fuel passage is provided to the annular passage.

摘要： The objective of the present invention is to realize the structure, of a fuel injection valve, in which bouncing of the needle can be suppressed and the armature position can be fixed while the valve is closed, without increasing the number of components and the number of processes. In a fuel injection valve including an armature that is repelled or attracted by a core, by de-energizing or energizing a coil, a needle that opens or closes a valve seat in accordance with a reciprocal travel of the armature, and a valve-closing spring that biases the needle so as to close the valve, when the coil is de-energized, the valve-closing spring is disposed on the armature, and the needle and the armature are fixed in such a way that the armature can travel in an axis direction by a predetermined amount with respect to the needle.
