Abstract

UN AMORTISSEUR COMPREND UN CYLINDRE 2 ET UNE TIGE DE PISTON 3 QUI TRAVERSE UNE DES DEUX PAROIS EN BOUT DE CE CYLINDRE. UN ENSEMBLE DE PISTON MONTE SUR LA TIGE DE PISTON DIVISE LA CAVITE INTERIEURE DU CYLINDRE EN DEUX CHAMBRES DE TRAVAIL 5, 6 QUI COMMUNIQUENT ENTRE ELLES PAR DEUX BRANCHES PARALLELES 11, 12 D'UN PASSAGE MENAGE A TRAVERS LE PISTON 4. CHAQUE BRANCHE EST COMMANDEE PAR UNE SOUPAPE RESPECTIVE. LE DEPLACEMENT AXIAL DE LA TIGE DE PISTON 3 EST AMORTI DANS UN SENS EN FONCTION DE SA VITESSE. LA SOUPAPE 16 DE LA PREMIERE BRANCHE 11 S'OUVRE A PARTIR D'UNE VITESSE PREDETERMINEE DE LA TIGE DE PISTON, TANDIS QUE CELLE 19 DE LA SECONDE BRANCHE SE FERME A PARTIR D'UNE DIFFERENCE DE PRESSION PREDETERMINEE ENTRE LES DEUX CHAMBRES DE TRAVAIL.
