  • Method of making a solenoid actuated fuel injector
    Patent number: 6405427
    Abstract: A solenoid actuated fuel injector for use with an internal combustion engine includes a hydraulic metering subassembly and a power group subassembly. The hydraulic metering subassembly includes a fuel path and an armature/needle assembly movable between valve closed and open positions and calibrated independent of the power group subassembly to meter the discharge of fuel from the injector. The power group subassembly provides a magnetic flux return path and electromagnetic forces that move the armature/needle assembly between the valve closed and open positions. By providing an independently operational, calibrated hydraulic subassembly, a variety of different types of power group subassemblies may be used with the hydraulic metering subassembly resulting in design flexibility and a manufacturing process that is more flexible and cost efficient.
