摘要： A solenoid actuator includes a hard guide piece and a soft flux piece. The hard guide piece has a stop surface ground to create a final air gap distance between the soft flux piece and a stator assembly when the stop surface on the guide piece is in contact with the stator assembly. The final air gap is set by grinding the stop surface on the guide piece so that the distance between the stop surface on the guide piece and a top surface on the soft flux piece along an axis of the guide bore is equal to the final air gap. The step of grinding the armature assembly may be done after attaching the guide piece and the flux piece together. In an exemplary embodiment, the step of grinding the stop surface and associated guide surface(s) are performed in a single chucking.

摘要： A fuel injector includes a piezoelectric actuator subassembly having a casing and a piezoelectric element disposed within the casing. The piezoelectric element has an operating temperature range and includes a thermally contractive material having a negative thermal expansion coefficient over a second temperature range overlapping with the operating temperature range. A preload control element is coupled with the piezoelectric element and includes a thermally expansive material having a positive thermal expansion coefficient over the second temperature range. The preload control element maintains a constant preload on the piezoelectric element over a wide temperature range to inhibit temperature induced variability in operation, and can axially lengthen in opposition to axial shortening of the piezoelectric element, responsive to a temperature increase.

摘要： A control valve assembly includes a one-piece valve movable between a first position at which the valve closes a seat defined by a housing and positioned fluidly between a fluid inlet and a first fluid outlet, and a second position at which the valve is out of contact with the seat. The valve includes an outer diameter having an annular seating shoulder located thereon which is configured to contact a frustoconical surface of the seat when the valve is at the first position, and the annular seating shoulder is further configured to deform in response to contacting the frustonical surface without changing a seating diameter associated therewith. Closing the seat with the annular seating shoulder reduces performance variability of the valve over time.

摘要： A fuel system for an internal combustion engine includes a plurality of nozzle groups and a plurality of pump groups. A common rail is fluidly connected with each of the nozzle groups, and each of the pump groups includes a mechanically actuated pressure intensifier having a tappet which can selectively intensify a fuel injection pressure in a corresponding one of the nozzle groups. Each of the mechanically actuated pressure intensifiers is movable in response to rotation of a cam, and includes a spill valve having a first position at which fuel is displaced from the pump group to a low pressure space and a second position at which fuel is displaced to a corresponding one of the nozzle groups.
