ELECTROMAGNETIC FUEL INJECTOR WITH TAPERED ARMATURE/VALVE Abstract of the Disclosure An electromagnetic fuel injector is provided with a tapered armature valve plate operatively positioned by means of a locator 80 that it is arranged so as to, in effect, pivot from a spring biased position at which it seats against a valve seat associated with a plurality of orifice discharge passages located concentrically about the axis of the injector to a second position adjacent to the working surface of the pole piece means of the associate solenoid. Preferably, the electromagnetic fuel injector is of the bottom feed type whereby it can be supplied with fuel in excess of the amount to be injected, with the flow path of fuel being arranged so that the excess fuel will purge vapors from the injector and cool the solenoid coil therein.
