Abstract
L'INVENTION CONCERNE UN ARRANGEMENT POUR OBTENIR UNE COURSE EGALE DE CYLINDRES HYDRAULIQUES, EN PARTICULIER POUR UN ELEVATEUR DE VOITURE. CET ARRANGEMENT POUR COMMANDER LE DEPLACEMENT D'UNE PLATE-FORME 3 PAR DES CYLINDRES 1, 2 COMPREND DEUX ORGANES DE COMMANDE 8, 16 RESPECTIVEMENT D'ELEVATION ET D'ABAISSEMENT RELIES D'UNE PART A UNE POMPE 4 ET A UNE VANNE A COMMANDE MANUELLE 5 ET D'AUTRE PART AUX DEUX CYLINDRES. LES DEUX ORGANES SONT INTERCONNECTES RIGIDEMENT ET COMMANDES PAR UN ARRANGEMENT COMPRENANT UN LEVIER 22, UN CABLE 24 ET UN RESSORT 29 DE TENSION DU CABLE. DES CLAPETS DE NON-RETOUR 13, 14, 19, 20 SONT UTILISES POUR ISOLER LES CYLINDRES. L'INVENTION S'APPLIQUE A UNE PLATE-FORME ELEVATRICE DE VOITURE.
