Abstract

L'invention a pour objet un circuit hydraulique commandant les mouvements d'une soupape de passage de gaz. Entre un piston 8 manoeuvré par une came 2 et un piston 11 qui commande une soupape 14, se trouve une conduite 9 sur laquelle sont montés un premier orifice d'étranglement 21 assurant une purge permanente et un second orifice d'étranglement réglable 24 permettant de régler la course de la soupape 14 par l'effet d'une fuite contrôlée et réglée. L'invention est utile pour la commande des soupapes sur les moteurs thermiques et sur les compresseurs.
