Abstract
An electromagnetically controlled pneumatic valve includes a chamber having a first nozzle of magnetic material in opposed relation to a second nonmagnetic nozzle. A cylindrical, permanent magnet, valve member may become seated upon one or the other of the nozzles in response to an electromagnetic field generated by a coil surrounding the first nozzle. A conduit from the chamber between the nozzles connects to a pneumatic load such as an air tool.
