Abstract

Dans le procédé selon l'invention, des systèmes de bloc d'alimentation à base de liquide hydraulique sont utilisés avec tous types de valves commandées à fonctionnalité microprocesseur, moteurs pas-à-pas, etc., afin de dériver une pression hydrostatique. Avec ce système de commande et une pression hydrostatique excessive, des systèmes requis à couple élevé peuvent être mis en rotation en remplaçant les moteurs à puissance plus élevée et réduisent le besoin en puissance par rapport aux procédés existants.
