ELECTROFLUIDIC JET/FLAPPER TRANSDUCER, AND SERVO VALVE EQUIPPED WITH SUCH A TRANSDUCER |
摘要 |
<p>The transducer comprises a piezoelectric double-layer plate, the movements of which, under the effect of electrical signals, directly control the flow from one or two spray nozzles. The plate is mounted in a floating manner, without any fastening, between fixed supports of the knuckle-type which do not impede the free deformation (flexion or bending) of the plate. The invention makes it possible to increase the "signal-voltage/movement" ratio of the plate and reduce the hysteresis to obtain greater accuracy and reliability of response.</p> |
