  • Patent number: 7406945
    Abstract: A fuel system includes a fuel rail that communicates fuel at a first pressure through a fuel amplifier to a fuel injector. The fuel pressure amplifier increases the pressure from the first pressure to a second pressure. The second pressure is higher than the first pressure and is communicated through each of the plurality of fuel injectors. The fuel amplifiers provide for the application of fuel pressure without the need to configure each and every fuel system component for the corresponding higher pressures.

  • Publication number: 20050034707
    Abstract: A control valve has a control valve body with a bore and a plurality of fluid connections. A spool valve assembly is moveable within the bore between a first position and a second position. The spool valve assembly has a first hydraulic surface and a second opposing hydraulic surface in fluid communication with a first fluid connection and a second fluid connection, respectively, of the plurality of fluid connections. An actuator has a fluid connection between ambient and the second hydraulic surface of the spool valve assembly. When a current is applied to the actuator, the fluid connection is opened to ambient and the hydraulic force acting on the first hydraulic surface is greater than the hydraulic force acting on the second hydraulic surface such that the spool assembly is moveable to the first or open position. When the actuator is closed, the fluid connection to ambient is blocked and the fluid pressure increases against the second hydraulic surface via fluid supplied by the second fluid connection.

  • Publication number: 20050034709
    Abstract: A control valve for an injector includes a spool valve assembly having a spool moveable between an open position and a closed position. The spool has a first hydraulic surface and a second hydraulic surface. A first chamber is in fluid communication with the first hydraulic surface of the spool and a second chamber is in fluid communication with the second hydraulic surface of the spool. An actuator is in fluid communication with the second hydraulic surface of the spool. The actuator, in an open position, provides a fluid path to ambient such that a hydraulic force acting on the first hydraulic surface of the spool becomes greater than a hydraulic force acting on second hydraulic surface of the spool. A flow path is in fluid communication with the second hydraulic surface to decrease a force acting on the second hydraulic surface of the spool during spool operation.

  • Patent number: 6662783
    Abstract: A control valve for a fuel injector generally includes a valve body and a spool positioned within a bore of said valve body. The spool is slideable between a first and second position. The control valve also comprises a first bore in fluid communication with a rail inlet of the fuel injector, a cross bore positioned within the valve body and offset from the first bore, and a groove located about the spool. The groove provides fluid communication between the cross bore and the first bore when the spool is in the first position, and seals fluid communication when the spool is in the second position. At least two solenoids are provided on opposing sides of the spool for moving the spool between the first and second positions, and a non-magnetic barrier is provided between the solenoids and the spool.

  • Patent number: 6591812
    Abstract: A rail connection assembly includes an outer rail connection tube having a rail connection outlet, a component having a substantially centrally located bore that is fixed to the outer rail connection tube remote from said rail connection outlet, and a piston adapted for movement between a first position and a second position, with the second position being remote from said bore. A nipple having a predetermined cross section and extends from the piston and is slidably movable into and remote from said bore when the piston is moved between the first and second positions, respectively. A fluid communication path exists between the bore and the rail connection outlet. This provides a pilot injection of fuel when the piston moves into an intermediate position between the first and second positions and a full injection of fuel when the piston reaches the second position.
