Abstract

UNE SECURITE CONTRE LES EFFETS DE RUPTURES DE CONDUITE COMPORTE DES ORGANES D'OBTURATION SEPARES DISPOSES AUX EXTREMITES DES DEUX BRANCHES D'UNE CONDUITE DOUBLE ET QUI FONCTIONNENT AUTOMATIQUEMENT EN REPONSE A L'ETABLISSEMENT D'UNE DIFFERENCE DE PRESSION INADMISSIBLEMENT GRANDE ENTRE UNE PRESSION DE REFERENCE ET LA PRESSION REGNANT DANS UN RACCORD DE CONDUITE. COMME PRESSION DE REFERENCE, ON UTILISE DE PREFERENCE LA PRESSION REGNANT DANS LE RACCORD DE CONDUITE DE L'AUTRE BRANCHE DE LA CONDUITE DOUBLE. APPLICATION PARTICULIERE A LA PROTECTION DE DISPOSITIFS DE SUPPORT HYDRAULIQUES DE TRAIN DE ROULEMENT CONTRE LES RUPTURES DE CONDUITE.
