Abstract
An electromagnetic fuel injector has an orifice director plate, mounted downstream of the orifice passage defined when the solenoid actuated valve of the injector is in the open position relative to its associated valve seat, for controlling static flow from the injector. The orifice director plate is provided with flow orifice passages that are axially downwardly inclined and radially inward extending so as to direct the jets of fuel flow, as desired, relative to the central axis of the orifice director plate and thus to the axis of the spray tip discharge passage of the injector.
