Abstract
CET APPAREIL COMPREND UNE SOUPAPE 5 INTERCALEE DANS LA CONDUITE D'ARRIVEE DU COMBUSTIBLE AU GENERATEUR ET DONT L'OBTURATEUR 13 CHARGE PAR UN RESSORT 14 SE FERME AUTOMATIQUEMENT EN REPONSE A UNE ELEVATION DE LA TEMPERATURE DE L'EAU AU-DESSUS D'UNE LIMITE DE SECURITE OU EN REPONSE A UNE AVARIE D'UN ELEMENT DE CET APPAREIL. L'OBTURATEUR EST MAINTENU OUVERT PAR DES BILLES MAINTENUES ECARTEES PAR UN COULISSEAU. LE COULISSEAU DEGAGE LES BILLES ET LIBERE L'OBTURATEUR LORSQU'IL EST POUSSE PAR UN SOUFFLET ELASTIQUE 16 NORMALEMENT MAINTENU RETRACTE PAR SA DEPRESSION INTERIEURE. CETTE DEPRESSION EST DETRUITE PAR LA PRESSION DE VAPEUR DU CAPTEUR 2 A LA TEMPERATURE DE SECURITE OU PAR SUITE D'UNE RUPTURE DU CAPTEUR 2, DU TUBE 17 OU DE LA PAROI DU SOUFFLET.
