Abstract:
A method of manufacturing an encapsulated stator for a liquid metering solenoid comprising the steps of:providing a bobbin assembly comprising an electrically conductive coil wound around a bobbin and at least one ferrous core positioned adjacent the bobbin;providing at least one electrical conductor having a first end connected to the coil and a distal second end;providing a plunger guide made from a substantially non-ferrous material;inserting the plunger guide through a center passage of the bobbin to form a stator assembly comprising the bobbin assembly and the plunger guide; andmolding a plastic material over and around the stator assembly to substantially surround the stator assembly but leave the upper end of the plunger guide and the second end of the conductor exposed adjacent a top end of the encapsulated stator, and leave lower ends of the plunger guide and core exposed adjacent a bottom surface of the encapsulated stator.
