ABSTRACT:
A gaseous fuel injector for an internal combustion engine or a propulsion system using fuel cells has an electromagnetic solenoid with a flat rectangular armature which seats against a seat member to form a valve. The valve is kept in a closed position by the differential between the fuel pressure on one side and the atmospheric pressure or the ambient pressure in the discharge chamber on the other side with additional closing force being provided by a spring which abuts against the armature. With each pulsating actuation of the coil of the solenoid, the armature is driven away from its seat to open the valve formed thereby providing an injection of gas from the injector. The injector has a discharge nozzle which is integrally formed therewith. A centrally located aperture is formed in the armature which along with the side space afforded by the rectangular shape of the armature provides dual apertures for the flow of gas through the injector.
