Abstract

CE VERIN COMPORTE DES DISPOSITIONS PERMETTANT LA MANOEUVRE MANUELLE EN CAS DE COUPURE DE SON ALIMENTATION. IL COMPREND UN BLOC D'ALIMENTATION DANS LEQUEL DEUX ORIFICES FONT COMMUNIQUER AVEC L'EXTERIEUR DEUX CONDUITS COAXIAUX RESPECTIFS DEBOUCHANT AUX DEUX EXTREMITES D'UN PETIT CYLINDRE, A L'INTERIEUR DUQUEL SONT MONTES DEUX PETITS PISTONS. CHAQUE CONDUIT MENE VERS L'UNE DES CHAMBRES DU VERIN ET COMPREND UN CLAPET POUVANT ETRE ACTIONNE PAR UN POUSSOIR QUE COMPORTE L'UN DES DEUX PETITS PISTONS. UN DOIGT PIVOTANT, MANOEUVRABLE DEPUIS L'EXTERIEUR, PERMET DANS UNE POSITION, D'ECARTER LES DEUX PETITS PISTONS POUR OUVRIR LES DEUX CLAPETS; DANS UNE AUTRE POSITION IL PERMET LE RAPPROCHEMENT ET LE CONTACT DES DEUX PISTONS, L'UN DES CLAPETS POUVANT ALORS SE FERMER. APPLICATION AUX PORTAILS MOTORISES.
