<p>A relatively compact and vibration-insensitive I/P electric-to-pressure converter includes a flexure (27) from which an annular electromagnetic coil (31) depends into an annular gap (26) defined by the pole pieces (21, 24) of a permanent magnet assembly (22). A compressed air exhaust nozzle (16, 19) is located below the central region (29) of the flexure (27) which controls the rate of exhaust of air from the nozzle (16, 19), and therefore the output pressure of the converter, in dependence upon the magnitude of an electrical input current applied to the coil (31). <IMAGE></p> |
