Abstract
In a device for converting electric signals into pneumatic signals, a soft-iron core (3) and a coil (2) are arranged stationary. The soft-iron core has an air gap (7) between two pole shoes (5, 6). A permanent magnet (8) is movably arranged within this gap (7) or directly in front of it. The permanent magnet can be fastened, for instance, to one lever arm of a rocker (9). The other lever arm of the rocker (9) is then developed as baffle plate (11) adapted to throttle the stream of air emerging from a pneumatic nozzle (12) to a greater or lesser extent depending on the position of the rocker. The dynamic pressure of this stream of air is fed via a booster (15) to an outlet (20).
