Abstract
A coil assembly for a solenoid valve includes a sealing member having a sealed cavity that generally encircles an opening containing an electrical lead extending from the windings of the coil. The sealing member is disposed within a encapsulating material that is pressure molded around the windings of the coil assembly. During the pressure molding process, the pressure from the molding process exerts a force on the outermost side of the sealing member and compresses the outer member. The force being exerted to the outermost diameter is transferred through the sealed cavity to the innermost portion of the sealing member forcing it into a forced intimate contact with the lead. The force on the lead is maintained after the pressure from the molding process is removed. This arrangement provides a seal between the lead and the sealing member that is effective to prohibit damaging elements reaching the windings contained in the coil assembly.
