ABSTRACT:
An electromagnetic valve assembly having a dual armature solenoid for controlling two valves is disclosed. In one embodiment, the solenoid may include a first pole piece, a second pole piece spaced from the first pole piece, a coil disposed about at least a portion of the first pole piece, a first armature extending laterally across the first pole piece and the second pole piece, and a second armature extending laterally across the first pole piece and the second pole piece. In one illustrative embodiment, the first armature and the second armature pivot relative to the second pole piece. In another illustrative embodiment, the first armature and the second armature pivot relative to the first pole piece. In yet another illustrative embodiment, the first armature and the second armature pivot relative to opposite pole pieces. In any case, the coil may electromagnetically actuate the first and second armatures to selectively open and/or close corresponding valves or other actuatable components.
