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.

Pressure transducer

A variable output nozzle for permitting the output of air or gas from the nozzle to be varied. The variable output nozzle includes a nozzle housing having a bore located therein, a spherical ball located within the bore for reciprocal movement within the bore and an aperture in the nozzle housing for supplying pressurized air or gas to the bore in the nozzle housing. A plurality of slots are also located in the nozzle housing and extend into the upper portion of the bore and the bottoms of at least some of these slots are located at different depths so that the volume of pressurized air or gas exiting the nozzle will vary as the spherical ball passes the bottoms of the slots. The variable output nozzle is particularly useful as a pneumatic pressure transducer nozzle.
