Abstract:
A gaseous fuel injector for use in feeding gaseous fuel to a propulsion system comprising:a housing;an electrically controlled injector having an armature and a solenoid coil mounted in said housing;said armature being generally rectangular and having a substantially flat surface;a single valve seat member;the flat surface of said armature being in opposing substantially parallel relationship with said valve seat member;means for urging said armature to bring the flat surface thereof in abutment against the valve seat member to provide a closed valve position;a single outlet passage formed in said housinggaseous fuel being fed into one end of said housing and exited through said single outlet passage located at the opposite end thereof; andmeans for feeding control pulses to said solenoid coil to drive said armature away from said valve seat member to an open position thereby opening the valve formed thereby to permit gaseous fuel to exit from said housing through said single outlet passage.
