Abstract
Système de robinet (10) dans lequel un élément piézo-électrique (38) est utilisé pour l'activation d'une vanne de réglage de fluide (18), de manière qu'un minimum d'énergie électrique soit consommé. Ledit élément piézo-électrique (38) active une soupape de pression pilote (36), ce qui permet le passage d'un fluide de commande dans un robinet de commande principal (44). Ledit fluide induit l'activation par le robinet de commande principal (44) d'un élément de travail (16), lequel actionne à son tour la vanne de réglage de fluide (18). Un ensemble de commutation (70) est utilisé pour activer l'élément piézo-électrique (38). Ledit ensemble (70) peut comporter divers types de dispositifs de commutations, tels que des dispositifs de commutation RF, des dispositifs de commutation optique, des dispositifs de commutation IR et des dispositifs de commutation électrique basse tension.
