Abstract

L'INVENTION CONCERNE UN DISTRIBUTEUR HYDRAULIQUE DE TYPE NOUVEAU. LE DISTRIBUTEUR HYDRAULIQUE COMPREND UN CORPS 1 ET UN TIROIR 2, AINSI QUE DES MOYENS DE COMMANDE CONSTITUES PAR DEUX BUTEES 7 ET 8 SOLIDAIRES D'UNE TIGE DE LIAISON 9 ENGAGEE DANS UN PASSAGE AXIAL 10 DU TIROIR ET DANS LES PASSAGES AXIAUX RESPECTIFS 11 ET 12 DE DEUX PISTONS D'ASSISTANCE 13 ET 14. LE TIROIR 2 ET LES PISTONS D'ASSISTANCE 13 ET 14 SONT MONTES AVEC UN JEU IMPORTANT ENTRE LES BUTEES 7 ET 8. LES PISTONS D'ASSISTANCE, DISPOSES DE PART ET D'AUTRE DU TIROIR 2, DELIMITENT DES CHAMBRES ARRIERE 17 OU 18 ALIMENTEES EN FLUIDE A BASSE PRESSION. APPLICATION: OBTENTION D'UN DEPLACEMENT PROGRESSIF DU TIROIR.
