| Summary: | The present invention relates to electromagnetic fuel injection valves for use in internal combustion engines.
A press-machined fuel induction pipe a hollow tubular type of fixed core with a flange at its upper end, and a nozzle holder that was press-machined into a slender tubular shape and has an orifice plate equipped with a valve seat at the lower end of the nozzle holder, are connected by welding. The upper inner surface of nozzle holder and the outer surface of fixed core are welded after being press-fit. A movable core and a valve body are connected to the welded assembly via a point having a spring function. On the outer surface of nozzle holder is provided an electromagnetic coil the outside of which is provided with a tubular yoke whose upper end is connected by welding to the flange of fixed core and whose lower end is press-fit on the outer surface of nozzle holder |
