Abstract

Valve hydraulique de commande comportant un boîtier à l'intérieur duquel est défini un alésage, un manchon de valve disposé en rotation à l'intérieur de alésage et des éléments d'entrée et de sortie susceptibles d'entrer en rotation qui font saillie à l'intérieur de l'alésage du manchon de manière à se faire face. Des tiges axiales disposées entre le manchon de valve et l'élément d'entrée définissent une paire de chemins d'écoulement de fluide qui reçoivent du fluide sous pression. L'élément d'entrée est susceptible d'entrer en rotation par rapport au manchon pour augmenter l'écoulement de fluide dans l'un des chemins d'écoulement et pour diminuer l'écoulement de fluide dans l'autre chemin. Les tiges se prolongent de manière à être disposées dans des rainures se faisant face définies dans le manchon et l'élément de sortie de telle sorte que ces derniers sont reliés en rotation.
