The invention concerns a hydraulic circuit (17) and a control valve (18) dimensioned to be capable of providing the greater part the control surface (3) actuating, which requires less power than the system maximum performances. Moreover, a bi-directional hydraulic pump (23), driven by an electric motor (24), can supply backup power which, added to said circuit (17) power, can ensure said maximum performances.
Selon l'invention, un circuit hydraulique (17) et une valve de commande (18) sont dimensionnés pour pouvoir effectuer la grande majorité des actionnements de la gouverne (3), qui nécessitent une puissance inférieure aux performances maximales du système. Par ailleurs, une pompe hydraulique bidirectionnelle (23), entraînée par un moteur électrique (24), peut fournir une puissance d'appoint qui, additionnée à la puissance dudit circuit (17), permet d'assurer lesdites performances maximales.
