Title (EN) METERLESS HYDRAULIC SYSTEM HAVING MULTI-ACTUATOR CIRCUIT
(FR) SYSTÈME HYDRAULIQUE SANS COMPTEUR PRÉSENTANT UN CIRCUIT À ACTIONNEURS MULTIPLES
Abstract: front page image
(EN)A hydraulic system (56) is disclosed. The hydraulic system may have a pump (66), a rotary actuator (42L), a linear actuator (34), and a closed- loop circuit (58) fluidly connecting the pump to the rotary and linear actuators. The hydraulic system may also have at least one valve (78, 80, 82, 84) configured to switch fluid flow direction from the pump through the linear actuator during fluid flow in a single direction through the rotary actuator.
(FR)L'invention concerne un système hydraulique (56). Le système hydraulique peut comporter une pompe (66), un actionneur rotatif (42L), un actionneur linéaire (34) et un circuit en boucle fermée (58) reliant de manière fluidique la pompe aux actionneurs rotatif et linéaire. Le système hydraulique peut également comporter au moins une soupape (78, 80, 82, 84) conçue pour commuter le sens d'écoulement du fluide depuis la pompe à travers l'actionneur linéaire, lors d'un écoulement unidirectionnel du fluide à travers l'actionneur rotatif.
