Abstract

L'invention concerne un vérin de manoeuvre et de contreventement à dispositif interne de verrouillage à commande hydraulique et mécanique de déverrouillage sous charge. Il comprend un verrou principal, constitué de griffes élastiques 7 solidaires du cylindre 1, susceptibles de venir s'encliqueter derrière un redan 11 porté par la tige 10 et d'être verrouillées par un piston verrouilleur 18, ainsi qu'un verrou secondaire à faible travail de commande, pour verrouiller le piston verrouilleur principal. Le dos des griffes 7 est conformé en pan incliné 8 et coopère avec une surface d'appui de forme correspondante sur le piston verrouilleur 18, qui peut être déverrouillé soit hydrauliquement, sous l'effet d'une pression de manoeuvre de la tige 10 dans le cylindre 1, soit mécaniquement par une contre-tige 15. Le déverrouillage du vérin secondaire etant suivi de celui du verrou principal, assisté en utilisant la charge du vérin au moyen du pan incliné 8 des griffes 7. Application à l'équipement des trains d'atterrissage d'aérodynes et des éléments associés.
