Abstract
A fuel injector that includes an injector control valve assembly. The injector control valve assembly includes a contact spring positioned between a fuel injector upper body and the injector control valve assembly to isolate a stator housing from clamping forces that occur during fuel injector assembly and clamping in an internal combustion engine. The injector control valve assembly further includes a cartridge configuration that permits preassembly of the injector control valve assembly prior to mounting in the fuel injector.
