Abstract

LA PRESENTE INVENTION CONCERNE UN ATTENUATEUR D'INSERTION FONCTIONNANT COMME FILTRE DE REJET A LARGE BANDE DE FREQUENCES POUR ATTENUER LES PULSATIONS RENCONTREES PAR EXEMPLE DANS L'ECOULEMENT D'UN COMPARTIMENT DE TETE D'UNE MACHINE A PAPIER. SELON L'INVENTION, L'ECOULEMENT LIQUIDE TRAVERSE DEUX COMPARTIMENTS SITUES RESPECTIVEMENT AU-DESSUS ET EN DESSOUS DES DEUX CHAMBRES D'UN DIAPHRAGME25. DE L'AIR COMPRIME INTRODUIT PAR LES ORIFICES47 ENTOURE LA CONDUITE13 ET PEUT PENETRER DANS LECOMPARTIMENT SITUE ENTRE LES DEUX BRANCHES A TRAVERS DEUX FEUTRES POREUX51 SITUES DE PART ET D'AUTRE. LORSQUE LA PRESSION DU LIQUIDE DIMINUE BRUSQUEMENT, LA DEFLECTION DES DEUX BRANCHES DU DIAPHRAGME DECOUVRE DEUX ORIFICES56A, 57A PAR LESQUELS LE GAZ EXCEDENTAIRE EST EVACUE, LES PRESSIONS DU LIQUIDE ET DU GAZ ETANT AINSI DE NOUVEAU EQUILIBREES. CE MAINTIEN DU DIAPHRAGME DANS UNE POSITION NEUTRE ET SENSIBLE LUI PERMET DE DEFLECHIR INSTANTANEMENT DANS LES DEUX SENS SELON LES BESOINS POUR ABSORBER LES PULSATIONS DU LIQUIDE.
