Abstract

Ce dispositif est du type de ceux comportant au moins un ajutage à pression dynamique muni d'un orifice d'entrée du fluide de commande, d'un orifice d'échappement situé à peu près dans l'axe de l'orifice d'entrée et d'un orifice desservant, par exemple un appareil d'inversion, ainsi qu'un élément d'obturation solidaire de la tige de piston d'un vérin et apte à fermer l'orifice d'échappement Dans le dispositif selon l'invention, l'ajutage 11, 11', disposé de façon réglable dans le sens axial, comporte un élément d'étanchéité 37 actionnable par l'élément d'obturation 61, qui est associé à un passage 34 entre l'orifice d'entrée 14 du fluide de commande sous pression et l'orifice d'échappement 17, et la relation entre l'élément d'obturation 61 et l'élément d'étanchéité 37 est telle que l'élément d'obturation 61 ferme l'orifice d'échappement 17 immédiatement après qu'il a amené l'élément détanchéité à libérer le passage 34. On obtient ainsi une réduction considérable de la consommation de fluide.
