Patent attributes
A module, direct fuel injector (10) includes a fuel module (46) having a valve body (12) defining an outlet opening (20) and including a seating surface (18). A needle 14, disposed in valve body, has a sealing surface (16). An armature (28) is coupled with the needle such that movement of the armature moves the needle between a closed position with the sealing surface engaging the seating surface and an open position with the needle moving outwardly from the valve body with the sealing surface being disengaged from the seating. A spring (38) biases the armature and thus the needle to the closed position. An inlet tube (22) is coupled to the fuel module defining an inlet of the injector. A power assembly (42) is separate from, but coupled to, the fuel module. The power assembly includes an electromagnetic coil (44) for causing movement of the armature, and a connector (43).
