Abstract

Cette invention concerne une valve de servo-commande Cette valve comprend un tiroir en deux parties présentant des canaux débouchant sur une interface, et un boisseau également en deux parties muni d'une cavité cylindrique, des lumières radiales débouchant dans cette cavité sur une interface Les interfaces du tiroir et du boisseau peuvent être disposées dans le même plan. Les lumières et les canaux se trouvent sur des côtés opposés des interfaces lorsque celles-ci sont placées dans le même plan On peut prêvoir dans le boisseau une seconde et même une troisième lumière pouvant être mises en communication avec un canal, la seconde lumière s'étendant au-delà de l'interface du boisseau, tandis que la troisième lumière peut être mise en communication avec le prolongement du canal. Les lumières et les canaux ont des formes rectangulaires. Un agencement de ce type est utilisable pour l'obtention d'une valve de servo-commande à chevauchement zéro utilisable par exemple pour la commande d'un vérin à double effet
