Abstract

DECELERATEUR DE DEBIT VOLUMETRIQUE D'APPAREILS HYDRAULIQUES DU TYPE A EVACUATION D'UN VOLUME DE FLUIDE CONTENU DANS UN CYLINDRE SOUS LA POUSSEE D'UN PISTON DONT L'AVANCE MASQUE SUCCESSIVEMENT DES ORIFICES MULTIPLES D'EVACUATION, LEDIT PISTON ETANT MUNI D'UN SEGMENT CLAPET CONTROLANT LE PASSAGE DU FLUIDE ENTRE SA FACE FRONTALE ET UNE CHAMBRE PERIPHERIQUE. LE PISTON EST DU TYPE FLOTTANT DANS LE CYLINDRE ET REPOUSSE EN L'ABSENCE DE PRESSION FLUIDE PAR UN RESSORT EN APPUI SUR LADITE FACE FRONTALE CONTRE UNE BUTEE VERS LA CHAMBRE DE RECEPTION OPPOSEE DU FLUIDE PROVENANT DU REFOULEMENT D'UN APPAREIL RECEPTEUR HYDRAULIQUE A AMORTIR, A L'OPPOSE DE LA CHAMBRE D'EVACUATION AMORTIE A TROUS MULTIPLES ET CONTENANT LE RESSORT DE REAMORCAGE. APPLICATIONS AUX AMORTISSEMENTS DE DECELERATION D'APPAREILS RECEPTEURS DANS DES CIRCUITS HYDRAULIQUES A HAUTE PRESSION.
