Abstract

Le dispositif de blocage et de déblocage comprend une tige 13 traversant deux mâchoires 10, 11 d'un premier élément mobile par rapport à un second élément 2. L'extrémité 14 de la tige 13 est solidaire du piston 20 d'un vérin 21, sollicité par des ressorts 24 dans le sens de traction de la tige 13. La tige 13 traverse librement la mâchoire 10 et son extrémité 15 est solidaire de la mâchoire il. L'alimentation en fluide de la chambre 26 du vérin 21 permet de supprimer la traction de la tige 13 et d'écarter les deux mâchoires 10, 11. Application notamment au blocage et déblocage de la traverse supérieure d'une machine d'essai de materiau sur des colonnes de guidage.
