Abstract

A.L'INVENTION CONCERNE UN REGULATEUR DE PRESSION. B.IL COMPORTE UN DISPOSITIF A DEUX RESSORTS AGISSANT SUR UN PISTON DE REGULATION QUI S'OUVRE POUR UNE PRESSION SUPERIEURE A LA PRESSION NOMINALE ET LAISSE PASSER L'AIR COMPRIME POUR LA COMMANDE D'UNE SOUPAPE DE SECURITE. AUX DEUX EXTREMITES DUDIT PISTON SONT PREVUS DES ELEMENTS D'ETANCHEITE QUI CONSTITUENT AVEC DES SIEGES DE SOUPAPE MENAGES SUR LE CARTER D'UNE PART LA SOUPAPE D'ADMISSION POUR LA COMMANDE DE LA SOUPAPE DE SECURITE, ET D'AUTRE PART LA SOUPAPE DE DESAERATION DU DISPOSITIF DE COMMANDE DE LA SOUPAPE DE SECURITE. C.APPLICATION AUX INSTALLATIONS DE STOCKAGE D'AIR COMPRIME.
