Title (EN) HYDRAULIC SYSTEM HAVING A PRESSURE COMPENSATOR
(FR) SYSTEME HYDRAULIQUE AYANT UN COMPENSATEUR DE PRESSION
Abstract: front page image
(EN)A hydraulic system (22) having a source (24) of pressurized fluid, a fluid actuator (16) with a first chamber (50) and a second chamber (52), and a body (90). The body has a first valve (26) configured to selectively fluidly communicate the source with the first chamber and a second valve (30) configured to selectively fluidly communicate the source with the second chamber. The body also has a proportional pressure compensating valve (36) to control a pressure of fluid directed between the source and the first and second valves and a supply passageway (61) disposed between the source and the first and second valves in parallel and the proportional pressure compensating valve is disposed within the supply passageway.
(FR)Système hydraulique (22) ayant une source (24) de fluide pressurisé, un actionneur de fluide (16) avec une première chambre (50) et une seconde chambre (52), et un corps (90). Le corps a une première vanne (26) configurée pour faire communiquer sélectivement de manière fluide la source avec la première chambre et une seconde vanne (30) configurée pour faire communiquer sélectivement de manière fluide la source avec la seconde chambre. Le corps a également une vanne de compensation de pression proportionnelle (36) pour commander une pression d'un fluide guidé entre la source et les première et seconde chambres et une voie de passage d'alimentation (61) disposée entre la source et les première et seconde vannes en parallèle et la vanne de compensation de pression proportionnelle est disposée dans la voie de passage d'alimentation.
