Abstract
An electromechanically actuated fuel injector and a solenoid stator assembly for an electromechanically actuated fuel injector are disclosed. The solenoid stator assembly comprises a cup shaped stator core assembly comprised of a plurality of magneto-conductive wire members of a predetermined length arranged in parallel, adjacent and abutting relationship relative to an adjacent wire member. These wire members are bound at one end thereof for some length less than the entire length of the wire members to form a central pole piece, and splayed umbrella like about the central pole piece at the opposite end thereof to form a first pole piece in concentrically spaced relationship relative to said center pole piece. The stator core thereby has a circular top portion and an open end disposed opposite said top portion and facing an armature in the fuel injector. The first pole piece is cylindrical in shape and substantially circular in cross-section extending in a direction perpendicular to said circular top portion, and the center pole piece is concentrically disposed in spaced relationship relative to said cylindrical first pole piece and extends in a direction perpendicular to said cylindrical top portion.
