ABSTRACT:
A relatively compact and vibration-insensitive electric-to-pressure converter includes an annular flexure from which an annular electromagnetic coil depends into an annular gap defined by the pole pieces of a permanent magnet assembly. A compressed air exhaust nozzle is located below the central region of the flexure which controls the rate of exhaust of air from the nozzle, and therefore the output pressure of the converter, in dependence upon the magnitude of an electrical input current applied to the coil.
