Abstract

Servovalve de commande, en particulier pour une servocommande hydraulique d'un aéronef, comportant un tiroir monté déplaçable dans le corps de la valve, manoeuvré de l'extérieur par une entrée de signaux de commande et muni d'au moins une arête de manoeuvre qui coopère avec un orifice de commande et l'ouvre ou le ferme lors du déplacement du tiroir. Le tiroir 58 est monté déplaçable dans une douille 42 mobile guidée dans le corps 14 de la valve, munie d'orifices de commande 48, 50 et pouvant être manoeuvrée de l'extérieur indépendamment du tiroir par l'intermédiaire d'une autre entrée de signaux de commande 70.
