  • Dual spray cone electromagnetic fuel injector
    Patent number: 4699323
    Abstract: An electromagnetic fuel injector is provided intermediate its solenoid actuated valve and a spray tip having an enlarged axial discharge passage extending therethrough with an orifice director plate having two sets of orifice passages extending therethrough with orifice passages of each set orientated relative to each other so as to produce a cone spray whereby this orifice director plate is operative to produce a dual diverging cone spray patterns for discharge out through the axial discharge passage.

  • Electromagnetic fuel injector with orifice director plate
    Patent number: 4646974
    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.
