ABSTRACT:
There is disclosed a fuel injection valve for internal combustion engines, which is used in combination with a fuel injection device for intermittent injection of fuel and which comprises a main body having a passageway extending between a fuel inlet and a fuel outlet, a valve member which cooperates with a valve seat disposed in the outlet and which is movable between a closed position and a fully open position in response to the pressure of the fuel fed into the passageway, the valve member being made up of a shaft member and a valve head, and is manufactured in such a way that a valve head made of a steel ball is welded by an instantaneous current passage welding process to one end of the shaft member and that the steel ball is cut perpendicularly to the axis on a smaller circle toward the shaft member than the equator of the steel ball so as to form an edge where the fuel jet flares.
