    caractérisé en ce que
    chaque fois un second élément de contrôle (34, 36) tel qu'un levier est prévu au niveau de chaque fois l'une des positions de fin de course du cylindre (24).
  10. Appareil de positionnement notamment selon au moins la revendication 5,
    caractérisé en ce que
    le second élément de contrôle tel que le levier (34, 36) comporte une seconde partie en saillie telle qu'une pointe (118, 122) dirigée vers la tête de cylindre, et à cette partie en saillie est associée une découpe telle qu'une rainure circulaire passant dans la zone frontale du cylindre ou du segment de boítier qui l'entoure (72, 74).
  11. Appareil de positionnement notamment selon au moins la revendication 10,
    caractérisé en ce que
    l'une des secondes parties en saillie telle que les pointes (118, 122) des seconds éléments de contrôle tels que les leviers (34, 36) sont déplacés sur l'un des segments d'extrémité de boítier (72, 74) en prenant en même temps le goujon correspondant (106, 108) dans une cavité associée (110, 112) du ou des éléments de commande (46, 48) tels que des tiges ou des poussoirs si le ou les segments de voie (16, 18) sont déplacés correctement.
  12. Appareil de positionnement notamment selon au moins la revendication 5,
    caractérisé en ce que
    dans le cas de plusieurs premiers éléments de contrôle tels que les tiges (50, 52), ceux-ci sont de même longueur ou sensiblement de même longueur.
  13. Appareil de positionnement notamment selon au moins la revendication 5,
    caractérisé en ce qu'
    au moins un premier élément de contrôle tel qu'une tige (50, 52) est relié de manière articulée au segment de voie (16, 18) à déplacer et à l'élément de commande tel qu'une tige ou un poussoir (46, 48), chaque fois par des articulations autour d'axes parallèles (60, 66 ; 62, 64).
  14. Appareil de positionnement notamment selon au moins la revendication 6,
    caractérisé en ce que
    le vérin (20) est issu d'une plaque de base (26) prévue dans une traverse creuse (128) dont est issue au moins une seconde fixation (26, 28) à partir de laquelle sont prévues de manière fixe, les tiges de piston (22), les axes (30, 32) d'au moins l'un des seconds éléments de contrôle pivotant autour de ceux-ci tels que des leviers (34, 36) ainsi qu'au moins un guide (40, 42) pour au moins un élément de commande (46, 48) issu de celui-ci ou fixe.
  15. Appareil de positionnement notamment selon au moins la revendication 5,
    caractérisé en ce qu'
    à l'intérieur de la tige de piston (214) traversant le cylindre (210) se trouve au moins un cylindre de commutation (226, 228) coulissant axialement, qui peut coulisser par un premier élément de ressort (234, 236) contre la force engendrée par le fluide de travail,
    la tige de piston, partant d'un perçage longitudinal (224) sollicité par le fluide de travail, est traversée par au moins un élément de verrouillage (262, 264, 266, 268) coulissant radialement, et le cylindre (210) dans une position de fin de course, est tenu par zone dans une chambre de réception (216, 218) dont il est issu, en s'appliquant contre le cylindre de commutation et
    une seconde tige de contrôle (227, 229) traversant la face frontale de la tige de piston est issue du cylindre de commutation, cette tige de contrôle coopérant avec au moins un second élément de contrôle (304) de sorte que lorsque le cylindre se trouve dans l'une des positions de fin de course et sous l'effet du déplacement du cylindre de commutation pour déverrouiller le cylindre, l'élément de contrôle est basculé de façon à être dégagé de l'élément de commande (46, 48) et le cylindre peut coulisser par rapport à l'élément de commande.
  16. Appareil de positionnement notamment selon au moins la revendication 15,
    caractérisé en ce que
    le second élément de contrôle est un levier coudé (304) avec un segment parallèle à l'axe de basculement d'une première branche (306) qui pénètre dans l'élément de commande (46, 48) ou dans une cavité (110) de celui-ci lorsque le cylindre (210) se trouve dans l'une de ses positions de fin de course.
  17. Appareil de positionnement notamment selon au moins la revendication 16,
    caractérisé en ce que
    le levier coudé (304) comprend une seconde branche (308) faisant de préférence un angle droit par rapport à la première branche (306) et qui coopère avec la seconde tige de contrôle (227, 229).
  18. Appareil de positionnement notamment selon au moins la revendication 17,
    caractérisé en ce que
    la seconde branche (308) est en forme de fourche et entre les branches (310, 312) de la fourche, passe la seconde tige de contrôle (227, 229) qui présente de son côté au moins une partie en saillie, recourbée (314), par laquelle la seconde branche est basculée de façon que la première branche (306) se dégage de la cavité (110) de l'élément de commande (46, 48), lorsque la seconde tige de contrôle (227) se raccourcit apparemment par le mouvement relatif entre le cylindre (210) et le cylindre de commutation (226, 228).
