Abstract
An electromagnetic actuator for a control valve module in an engine fuel injector, the module being a replaceable, independent element of the injector. The actuator has a stator with electromagnetic coil windings on a bobbin located within the control valve module. An armature is connected to a control valve in the module. The bobbin supports and precisely positions connector pins for the coil windings for registry with an external electrical wire harness.
