摘要： A fuel injector for an engine includes a continuous endoskeletal injector tube enclosing an imperforate continuous passage for fuel flow from an inlet end to an outlet end of the tube. A valve seat, injection valve, tubular magnetic pole, biasing spring and adjusting sleeve are mounted within the tube, optionally with other elements, all being exposed to fuel in the passage defined by the tube. A solenoid coil and a magnetic body together with mounting components and seals are mounted on the exterior of the tube where they are protected from exposure to the fuel, which is restricted to passage within the continuous tube. The body, pole and armature form a magnetic flux concentrating path operative to attract the armature to the pole and open the valve when the coil is energized. The solenoid coil may be preassembled with its connector in a body forming a separate coil assembly for subsequent installation on the injector tube. During assembly, the tubular pole may be adjusted to set the desired stroke of the injection valve prior to fixing the pole in the tube. Various other features are also disclosed.

摘要： A fuel injector for discharging fuel to an internal combustion engine is disclosed. The injector has a nozzle body with an annular valve seat surrounding a fuel discharge opening. A valve member is disposed in the internal cylindrical cavity and is moveable between a first, sealing position relative to the valve seat and a second, open position off of the seat. The valve member is guided in its movement, with respect to the valve seat by a valve guide member disposed in the nozzle, closely adjacent the annular valve seat. The valve guide member includes a disc shaped member having an outer perimeter which is configured for placement within the nozzle body and a tubular central portion which defines a central, valve guide opening. The valve guide opening extends through the tubular central portion to open adjacent the annular valve seat and is configured for circumjacent disposition relative to the valve member to guide movement of the valve. Fuel openings extend through the valve guide and are disposed circumferentially about the valve guiding central opening to conduct fuel around the valve guide member.
