Abstract

An enhanced safety coil that prevents crack formation and propagation to the coil windings from external sources and prevents exposure to fuel is provided. The enhanced safety coil may be used in a solenoid operated gas admission valve (SOGAV), and includes a plastic encapsulation body having at least one body de-stress feature, a coil wound on the plastic encapsulation body, a sleeve forming an outermost side protective wall configured to accommodate the plastic encapsulation body and coil therewithin, and potting provided between the plastic encapsulation body and the sleeve to seal the coil therein. The body de-stress feature is configured to reduce at least one of a formation or a propagation of a crack through the potting to the coil. The plastic encapsulation body forms retention latches configured to mate with a stator.
