摘要： A method to set a small air gap by improving the parallelism between the armature and the stator assembly includes attaching a guide sleeve to a pole piece and grinding the surfaces on the guide sleeve and the pole piece after the attaching step to improve parallelism. By decoupling the armature assembly from a valve member in a fuel injector assembly, an improved parallel orientation between the armature assembly and the stator assembly can be achieved by grinding the outer surface of the guide sleeve perpendicular to the planar bottom surface of the stator assembly in a single chucking. When the solenoid is energized, the armature is at a final air gap with the flux piece parallel to the bottom surface of the armature and the armature not in contact with the valve member.

摘要： Starting and ending an injection event are accomplished by respectively energizing and de-energizing a solenoid actuator to move an armature assembly with respect to a stator. The stator is protected from impact damage by maintaining the armature assembly out of contact with the stator. The inducement of residual magnetism in the armature assembly is reduced by stopping the armature assembly at a large radius outside of the magnetic flux circuit through the stator and soft magnetic armature of the armature assembly, when the solenoid actuator is energized.

摘要： A self-guided armature assembly for a single pole solenoid assembly includes an armature stem and an armature. The solenoid assembly includes a flux ring component and an actuator body. The armature is movable inside the flux ring. An axial air gap is defined between the top armature surface of the armature and a bottom stator surface of a stator assembly. A sliding air gap is defined between an inner diameter surface of the flux ring and an outer diameter surface of the armature. The self-guided armature is guided along the flux ring via a guiding interaction between the armature and the flux ring. The sliding air gap is smaller than the axial air gap. A stem clearance gap is defined between the armature stem and the actuator body. The sliding air gap is also smaller than the stem clearance gap.

摘要： A fuel injector for a common rail fuel system includes a common rail inlet port fluidly connected to a high pressure common rail, and a cooling inlet fluidly connected to an output from a lower pressure fuel transfer pump. The cooling fluid circulates internally through the fuel injector to cool a single pole solenoid via both internal and peripheral cooling passages. In order to accommodate a small spatial envelope while providing superior performance, a thin insulating layer may separate the solenoid coil winding from an inner pole piece, and small flux gap clearances may permit a flux carrying portion of the injector body to be a portion of the single pole solenoid assembly.
