Abstract
In one embodiment, a solenoid valve includes a supply port that fluidly communicates with a source of compressed air, a delivery port, a bore that selectively fluidly communicates with the supply and delivery ports, an armature in the bore, a pole piece in the bore, and a coil that is selectively energized with electrical power. The coil is around the armature and pole piece. The armature and pole piece selectively sealingly engage and move as an armature/pole piece single unit as a function of the electrical power in the coil. A position of the armature/pole piece within the bore controls fluid communication between the supply port and the delivery port.
