Abstract

L'invention concerne un ensemble soupape hydraulique (10) conçu pour fournir de manière sélective un fluide hydraulique à partir d'une alimentation de fluide hydraulique à un premier opérateur hydraulique (80) et à un second opérateur hydraulique (82). Ledit ensemble comporte des premier (32) et second (34) ports d'alimentation qui communiquent avec l'alimentation et quatre ports opérateurs (44, 46, 48, 50). Les premier (44) et troisième (48) ports communiquent avec le premier opérateur hydraulique (80). Les deuxième (46) et quatrième (50) ports communiquent avec le second opérateur hydraulique (82). L'invention concerne également des première (36) et seconde (38) chambres. La première chambre communique avec le premier port d'alimentation et les premier et deuxième ports opérateurs. La seconde chambre communique avec le second port d'alimentation et les troisième et quatrième ports opérateurs. Deux soupapes de sélection (60, 61) fonctionnant à l'unisson sont situées chacune dans une chambre. Les soupapes de sélection fonctionnent entre une première position à une première pression de fluide hydraulique et une seconde position à une seconde pression de fluide hydraulique. Dans une première position, les soupapes permettent une communication fluidique des premier et second ports d'alimentation avec les premier et troisième ports opérateurs, respectivement. Dans une seconde position, les soupapes permettent une communication fluidique avec les deuxième et quatrième ports opérateurs.
