ABSTRACT:
An improved electromagnetic actuator assembly with a fuel compatible bobbin part insertably supported in a recess of an engine fuel injector housing and sealed to prevent fuel leakage and any contact of fuel with the remaining portions of the actuator assembly. Resultantly, only the bobbin part is exposed to fuel and needs to be of costly fuel compatible material. The remainder of the actuator parts can be formed of more easily formed and less stable elastomeric material.
