Abstract

CETTE VANNE POSSEDE UN PISTON DIFFERENTIEL TUBULAIRE 8, 9 QUI DEFINIT DEUX CHAMBRES AUX EXTREMITES DU CORPS DE VANNE 1. LES CHAMBRES COMMUNIQUENT NORMALEMENT A TRAVERS LE PISTON, DE SORTE QUE L'EAU PEUT S'ECOULER DU TUYAU D'ARRIVEE 18 VERS LE TUYAU DE SORTIE 19. UNE CONTRE-PRESSION S'ETABLISSANT A LA SORTIE 19 AGIT SUR LA GRANDE FACE UTILE DU PISTON ET PEUT FAIRE AVANCER CELUI-CI CONTRE LA FORCE D'UN RESSORT 10. UN EPAULEMENT 22 DANS LE PISTON S'APPLIQUE ALORS CONTRE UN CLAPET 13, CE QUI COUPE LA LIAISON ENTRE LES TUYAUX 18 ET 19 A L'EXCEPTION D'UN PASSAGE ETRANGLE PAR UN TROU 23, PUIS SOULEVE LE CLAPET, CE QUI RELIE LA SORTIE 19 A UN DRAIN 20. LA DIMINUTION AINSI PRODUITE DANS LA PRESSION DE SORTIE FAIT REVENIR LE PISTON A SA POSITION DE DEPART, CE QUI RETABLIT LA COMMUNICATION NORMALE ENTRE LES TUYAUX D'ARRIVEE 18 ET DE SORTIE 19.
