(EN) PRIORITY FLOW CONTROL SYSTEM
(FR) SYSTEME DE COMMANDE D'ECOULEMENT PAR PRIORITE
Abrégé
(EN)
A priority flow control system in which the priority feature is obtained by progressively lowering the pressure differential of nonpriority valves (115, 116), once the maximum pump output is reached, so that all of the system valves (10, 115, 116) always retain their compensated proportional flow feature.
(FR)
Dans un système de commande d'écoulement par priorité, la caractéristique de priorité est obtenue par l'abaissement progressif du différentiel de pression de soupapes non-prioritaires (115, 116), une fois que le refoulement maximal de la pompe a été atteint, de sorte que toutes les soupapes du système (10, 115, 116) conservent toujours leur caractéristique d'écoulement proportionnel compensé.
