Abstract

L'INVENTION CONCERNE UN RESSORT PNEUMATIQUE A LOBE ROULANT, DU TYPE MANCHON, A RAPPORT LARGEURDIAMETRE ELEVE. LE RESSORT COMPORTE UN MANCHON SOUPLE 10 MONTE A UNE EXTREMITE SUR UN BOUCHON 12 ET, A L'AUTRE, SUR UN PISTON 14, LE BOUCHON ET LE PISTON ETANT FIXES CHACUN A L'UN DES DEUX ELEMENTS 24, 26 MOBILES L'UN PAR RAPPORT A L'AUTRE. UN ORGANE RIGIDE 32 EST MONTE A L'INTERIEUR DU MANCHON POUR LIMITER L'EFFET DE PLIAGE DE CE MANCHON DANS LA POSITION COMPLETEMENT ECRASEE, DE SORTE QUE, LORSQU'IL EST A NOUVEAU SOUS PRESSION ET SOUS CHARGE, LE MANCHON REPREND UNE CONFIGURATION AXIALEMENT SYMETRIQUE.
