Abstract

L'INVENTION CONCERNE UN AMORTISSEUR DE CHOCS BITUBULAIRE ET UNE SUSPENSION A MISE A NIVEAU AUTOMATIQUE. L'AMORTISSEUR COMPORTE DEUX TUBES 32, 34 DEFINISSANT ENTRE EUX UNE CAVITE QUI EST DIVISEE EN DEUX PARTIES 36, 38 PAR UN JOINT 70. LA PARTIE INFERIEURE 36 COMMUNIQUE AVEC LA CHAMBRE INTERIEURE DU CYLINDRE 34 PAR L'INTERMEDIAIRE DE CLAPETS ET EST RELIEE PAR UN RACCORD 82 A UNE SOURCE DE PRESSION REGLABLE D'UN SYSTEME DE MISE A NIVEAU AUTOMATIQUE. LA PARTIE SUPERIEURE 38 DE LA CAVITE RECUEILLE, PAR LES CANAUX 66 DE LA TETE 54, L'HUILE S'ECHAPPANT LE LONG DE LA TIGE 52 DU PISTON 50 ET EST RELIEE PAR UN RACCORD 84 AU RESERVOIR DE FLUIDE DU SYSTEME. L'INVENTION S'APPLIQUE NOTAMMENT AUX SUSPENSIONS DE TYPE MACPHERSON.
