  • Patent number: 5743238
    Abstract: A device is provided for pumping fuel through an internal combustion engine, comprising a pump cylinder and a piston reciprocable within the pump cylinder to define a pump chamber open at one end in which fuel is pressurized during a pump stroke of the piston. A fuel supply means is provided for supplying fuel to the pump chamber. The fuel supply means includes an electromagnetically actuated fuel control valve having an armature secured thereto, with the armature residing in a fuel-filled armature cavity. The armature electromagnetically cycled between a first position closing the fuel control valve and thereby closing the flow of fuel to the pumping chamber and a second position opening the control valve thereby allowing fuel to flow to the pumping chamber.
    Type: Grant

  • Patent number: 5526791
    Abstract: A high-pressure electromagnetic fuel injector having a dual-function valve directly controlled by an electric solenoid. Fuel pressure in a control volume chamber is controlled by the dual-function valve, and a separate control valve is controlled as a function of fuel pressure in the control volume chamber. A spray tip valve is, in turn, controlled as a function of the pressure of fuel controlled by the control valve to inject fuel through a spray tip orifice. The dual-function valve spills fuel during and after the control valve closes, thus reducing the amount of uncontrolled fuel at the end of an injection. The dual-function valve also provides a drain path through which to vent any fuel that leaks past the control valve.
