Abstract

UN MEMBRE DE PAROIS EXTERNE, COMME LA PAROI D'UN TUBE, RELIE A OU INTEGRAL A LA PIPE, AYANT UNE OUVERTURE EN COMMUNICATION AVEC L'EXTERIEUR DE LA PIPE. UN MEMBRE INTERNE EST PLACE FIXEMENT CONTRE L'INTERIEUR DU MEMBRE EXTERNE POUR SEPARER L'OUVERTURE DE LA TRAJECTOIRE DU FLUIDE A TRAVERS LA PIPE. LE MEMBRE INTERNE AYANT UNE SURFACE INTERIEURE DE FINISSANT UNE PORTION AU MOINS D'UNE CHAMBRE INTERIEURE EN COMMUNICATION AVEC LA TRAJECTOIRE DU FLUIDE DANS LA PIPE. LES MEMBRES INTERNES ET EXTERNES DEFINISSENT UN LABYRINTHE AYANT UNE REGION EFFECTIVE SECTIONALE EN FORME DE CROIX, UN CRIQUE A LA FIN POUR RECEVOIR LE FLUIDE PRESSURISE DE LA PIPE, ET UNE VOIE D'ECOULEMENT A LA FIN EN COMMUNICATION AVEC L'OUVERTURE DE LA PIPE POUR EMETTRE LE FLUIDE. UNE PLURALITE DE CANAUX COUPLANT DES PORTIONS INTERMEDIAIRES DU LABYRINTHE DIRECTEMENT AVEC L'OUVERTURE, ET AINSI EVITER LES PARTIES RESPECTIVES DU LABYRINTHE. UNE PAROI ELASTIQUE FONCTIONNANT COMME UNE VALVE, FORME UNE BARRIERE ENTRE LE CANAL ET LA CHAMBRE INTERNE ET REAGIT CONTRE LA PRESSION DANS LA CHAMBRE INTERNE POUR RESTREINDRE LE CANAL QUAND LA PRESSION DEPASSE UNE PREMIERE PRESSION DETERMINEE D'AVANCE. CECI EMPECHE LE FLUIDE D'EVITER UNE PARTIE DU LABYRINTHE, ELEVANT LA LONGUEUR EFFECTIVE DU LABYRINTE, ET AINSI REDUIRE LE COURANT QUI PREND PLACE DANS LA PRESSION PLUS ELEVEE
