ABSTRACT:
An electro-pneumatic valve which includes a spiral coil formed of electrically conductive material bonded to an insulative substrate. A second layer of substrate material is mounted substantially beneath the combination of the spiral coil and insulative substrate. The second layer of substrate has both a recess and an outer edge. There is a first passage communicating between the recess and the other edge. Within the recess is a magnetic armature that is operatively aligned with the spiral coil. There is a second passage communicating between the spiral coil and the recess. There is a magnetically conductive member located below the magnetic armature. The magnetic armature moves in response to electric current passing through the spiral coil to close the second passage.
