Abstract
An injector has an inlet and an outlet and an armature tube having passage structure and having a distal end spaced from the outlet. The passage structure communicates with the inlet. A movable, magnetic armature is coupled to the armature tube. An electromagnetic coil is associated with a stator and with the armature. A first spring is constructed and arranged, when the coil is not activated, to bias the armature tube so that the distal end engages in a sealing manner with a first seat to limit leakage of the gaseous fuel from the outlet. A second valve is movable in a valve body. A second spring is constructed and arranged, when the coil is not activated, to bias the second valve so that a seating surface thereof engages a second seat to close the outlet.
