ABSTRACT:
A modular fuel injector for an internal combustion engine, including a valve group subassembly and a power group subassembly. The valve group subassembly includes a first stator member, a second stator member, a non-magnetic shell disposed between the first and second stator members, a valve body, and an armature member. The armature member defines a first working air gap with the first stator member and a second working air gap with the second stator member. The armature member includes a closure member proximate an outlet end and contiguous to a seat in a first configuration. The power group subassembly includes an electromagnetic coil surrounding the passage, a housing encasing the coil, and an ovemold encapsulating the coil and the housing. The coil is energizable to provide magnetic flux that flows through the first and second working air gaps in the direction of the longitudinal axis.
