Title
(EN) HYDRAULIC SYSTEM
(FR) SYSTÈME HYDRAULIQUE
Abstract
(EN)
A hydraulic system for supplying fluid to an actuator comprising a variable speed prime mover drivingly coupled to a variable displacement hydraulic pump. The system is configured to deliver hydraulic fluid via fluid conduits to an actuator. It may deliver hydraulic fluid to an actuator at a first hydraulic pressure at a first rate of pressure rise; and at a second hydraulic pressure at a second rate of pressure rise. The first hydraulic pressure may be greater than the second hydraulic pressure; and the first hydraulic rate of pressure rise may be lower than the second hydraulic rate of pressure rise.

L'invention concerne un système hydraulique destiné à apporter un fluide à un actionneur, comprenant un moteur principal à vitesse variable couplé en entraînement à une pompe hydraulique à déplacement variable. Le système est conçu pour fournir du fluide hydraulique à un actionneur par le biais de conduites de fluide. Il peut délivrer du fluide hydraulique à un actionneur à une première pression hydraulique à un premier taux d'augmentation de pression ; et à une seconde pression hydraulique à un second taux d'augmentation de pression. La première pression hydraulique peut être supérieure à la seconde pression hydraulique ; et le premier taux hydraulique d'augmentation de pression peut être inférieur au second taux hydraulique d'augmentation de pression.
