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.

摘要： A solenoid actuated device such as a fuel injector includes an actuator body having a plurality of body pieces, and a single-pole solenoid actuator assembly positioned at least partially within the actuator body. The single-pole solenoid actuator assembly includes a one-piece compound armature housing having a load carrying component clamped between the first body piece and the second body piece, and a flux carrying component. The load carrying component includes a high structural strength and a low flux permeability, and the flux carrying component includes a low structural strength and a high flux permeability. A method of making a solenoid actuated device includes placing an armature at a sliding radial air gap with a flux carrying component of a one-piece compound armature housing, and establishing a structural load path by placing a load carrying component of the compound armature housing between a first actuator body piece and a second actuator body piece. A method of operating a single-pole solenoid actuator device includes supporting a flux carrying component of a one-piece compound armature housing with a load carrying component of the compound armature housing, channeling magnetic flux across a sliding air gap between a flux carrying component and the armature, and channeling a clamping load between a first actuator body piece and a second actuator body piece through the load carrying component of the compound armature housing.

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 solenoid actuator includes a stator assembly with a stator core of formed powder metal received in a stator housing. A ferromagnetic protective sleeve is in contact with and covers a majority of an inner end face and a cylindrical wall of the stator core, while a flux ring is in contact with and covers an outer end face of the stator core. An armature assembly includes an armature attached to a stem that is movable in an air gap relative to the ferromagnetic protective sleeve. A spring is operably positioned in the ferromagnetic protective sleeve but electrically isolated from the stator housing. The stator core is encapsulated to protect against erosion and fragmentation. A magnetic flux line around a solenoid coil passes through the stator core, the ferromagnetic protective sleeve, the armature, the flux ring and back to the stator core.
