Abstract
L'INVENTION EST RELATIVE A UN DISPOSITIF DE DEMARRAGE D'UN VERIN A PISTON AMORTI COMPORTANT SUR UNE FACE UNE BAGUE D'AMORTISSEMENT COOPERANT EN FIN DE COURSE AVEC UN ALESAGE DU FOND DU VERIN POUR FORMER UNE CHAMBRE D'AMORTISSEMENT, LEDIT ALESAGE COMMUNIQUANT AVEC UNE CHAMBRE DE COMMANDE DU VERIN. LE DISPOSITIF EST CARACTERISE EN CE QUE LE FOND EST MUNI D'UN CLAPET DE DEMARRAGE CONSTITUE PAR UN JOINT D'AMORTISSEMENT COOPERANT AVEC LA BAGUE D'AMORTISSEMENT ET DISPOSE FLOTTANT DANS UN LOGEMENT CIRCULAIRE ENTOURANT LADITE BAGUE, LE COTE DU LOGEMENT DISPOSE EN REGARD DU PISTON COMPORTANT UN MOYEN DE RETENUE DE LA BAGUE DANS LE LOGEMENT, LE COTE OPPOSE DU LOGEMENT COMPORTANT UN MOYEN DE COMMUNICATION AVEC LA CHAMBRE DE COMMANDE ET UN COLLECTEUR RELIE PAR UN CANAL DE LIAISON AVEC LA CHAMBRE D'AMORTISSEMENT. L'INVENTION S'APPLIQUE AU DEMARRAGE RAPIDE DES VERINS A PISTON AMORTI.
