Abstract
A solenoid coil assembly for a solenoid valve includes an electrical coil wound about a valve armature to develop a magnetic field for actuating the armature responsive to an electrical current passing through the coil. A case surrounds the coil. The case has opposite end walls and a top wall, a bottom wall and opposite side walls connected between the end walls. A pair of electrical connectors are connected to opposite ends of the coil and extend outwardly from the top wall. A metal yoke has opposite end walls connected by a top wall and a bottom wall. The yoke is received on the case with their respective end walls, top walls and bottom walls in alignment.
