Abstract

CE CONVERTISSEUR EST PLUS SPECIALEMENT DESTINE A TRANSFORMER UNE PRESSION D'ENTREE VARIANT PROPORTIONNELLEMENT A UNE GRANDEUR (UNE CHARGE D'ESSIEU PAR EXEMPLE) EN UNE PRESSION DE SORTIE VARIANT SUIVANT UNE CARACTERISTIQUE BRISEE QUI, APRES LA BRISURE, REJOINT PROGRESSIVEMENT LA PRESSION D'ENTREE A MESURE QUE CELLE-CI MONTE. SELON L'INVENTION, IL COMPREND UN CORPS 1 DANS LEQUEL SONT GUIDES UN PISTON 2 ET UN PISTON ANNULAIRE 3 QUI ENTOURE LE PISTON ETAGE 2, LE PISTON ANNULAIRE ETANT PRESSE PAR UN RESSORT 14 RELATIVEMENT FORT CONTRE UNE BUTEE 15 SUR LE PISTON ETAGE ET S'APPUYANT PAR UN RESSORT 17 PLUS FAIBLE SUR LE CORPS 1, ET UNE SOUPAPE REGULATRICE 8 DISPOSEE DANS LE CORPS 1 ET A TRAVERS LAQUELLE UN ORIFICE D'ENTREE 23 PEUT ETRE RELIE A UN ORIFICE DE SORTIE 24, LA PRESSION D'ENTREE AGISSANT SUR LA PARTIE 5 DE PLUS GRAND DIAMETRE DU PISTON ETAGE ET LA PRESSION DE SORTIE AGISSANT SUR LA PARTIE 7 DE PLUS PETIT DIAMETRE DU PISTON ETAGE ET SUR UNE FACE ANNULAIRE 29 DU PISTON ANNULAIRE 3.
