Abstract

L'invention concerne un circuit de commande valvulaire (10) comprend un premier élément de valve (12) connecté à un élément d'entraînement manuel (20) pour générer une veilleuse (21), un deuxième élément de valve (14) connecté à un deuxième commutateur de vanne (15), une unité de régulation et de commande (16) connectée à un convertisseur de tension électrique CC/CC (17) et apte à commander ledit deuxième commutateur de vanne (15) au moyen d'un signal de commande. Ledit circuit de commande valvulaire (10) comprend une première source d'énergie thermoélectrique (22) connectée au convertisseur de tension électrique CC/CC (17) et une deuxième source d'énergie thermoélectrique (23) connectée au moins soit au premier élément de valve (12), soit au deuxième élément de valve (14), lesdites sources d'énergie thermoélectrique (22, 23) étant toutes deux alimentées par une veilleuse (21).
