Abstract

L'appareil comprend un piston 13 se déplaçant dans un cylindre 16, une valve d'inversion 17, des premier 12b et second 12c passages pilotes pour commander l'opération d'inversion de la valve pilote 17. Il est caractérisé par le fait que ledit cylindre 16 possède un canal 16a, et que ledit piston 13 possède des premiers moyens de liaison 13e pour coupler par fluide ledit canal pilote 16a et ledit premier passage pilote 12b lorsque ledit piston approche ladite seconde position et des seconds moyens de liaison 13f pour coupler par fluide ledit canal pilote 16a et ledit second passage pilote 12c lorsque ledit piston approche de ladite première position pour inverser alternativement de cette façon ladite valve pilote 17. Application à la commande de mouvement alternatif.
