Abstract
DISPOSITIF DE COMMANDE DE CLAPET DOUBLE DE SECURITE. UN DISPOSITIF DE COMMANDE ELECTROPNEUMATIQUE DE CLAPETS DOUBLES DE SECURITE EST COMMANDE PAR DES CLAPETS PILOTES ACTIONNES PAR SOLENOIDES. LE DISPOSITIF DE COMMANDE COMPREND UNE BOBINE RELATIVEMENT COURTE MAINTENUE AU CENTRE PAR DES RESSORTS OPPOSES L'UN A L'AUTRE. LES CANAUX DE DETECTION COMPORTENT DES ORIFICES RELATIVEMENT PETITS QUI AIDENT A LA DESENSIBILISATION DU DISPOSITIF DE COMMANDE. LA CONSTRUCTION RESULTANTE RESISTE AUX DEPLACEMENTS EN REPONSE A DES IRREGULARITES MINEURES DES CLAPETS QUI CREERAIENT AUTREMENT DES CONDITIONS D'ARRET INDESIRABLES. APPLICATION AUX CLAPETS DE MACHINES TELLES QUE DES PRESSES.
