Abstract

An electric to pneumatic transducer that utilizes an electrical coil and a magnet assemble that is suspended by a plurality of springs. The magnet assembly acts upon a nozzle assembly in such a manner that movement of the magnet assembly causes a change in the release of pneumatic fluid from the nozzle assembly. The movement of the magnet assembly is accomplished by increasing or decreasing the electrical current that passes through the electrical coil with a corresponding increase in pressure or decrease in pressure exerted by the magnet assembly upon the nozzle assembly. The unique configuration of the springs also allows free up and downward vertical movement of the magnetic assembly and restricts or prevents sideward movement of the magnet assembly.
