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 COLLIER 30 EST MONTE AUTOUR DE L'EXTREMITE DU MANCHON QUI EST MONTE SUR LE BOUCHON 12 POUR EMPECHER LE MANCHON GONFLE DE ROULER VERS LE HAUT SUR LA BAGUE DE MONTAGE. 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.
