Abstract
CE SYSTEME DE SOUPAPE COMPREND, COMME LES SYSTEMES CONNUS, UNE SOUPAPE PRINCIPALE AVEC UN PISTON 5, TRAVERSE PAR UN ALESAGE AXIAL 19 FAISANT COMMUNIQUER UNE CHAMBRE DE FERMETURE 8 AVEC UNE RACCORD D'ARRIVEE 4 DU GAZ RESPIRATOIRE, ET UNE SOUPAPE AUXILIAIRE COMMANDEE PAR L'ACTION SUR UNE MEMBRANE DE LA PRESSION QUI REGNE DANS LE RACCORD D'INSPIRATION13. IL EST CARACTERISE EN CE QUE LA SOUPAPE AUXILIAIRE EST CONSTITUEE PAR UN CORPS 9 FORMANT UNE PAROI DE LA CHAMBRE DE FERMETURE MONTE DE FACON ETANCHE ET TRAVERSE PAR UN ALESAGE 10 DEBOUCHANT DANS UNE CHAMBRE DE DECHARGE 12 EN COMMUNICATION AVEC L'ATMOSPHERE (CANAL 15) ET PAR LA MEMBRANE 11, QUI ISOLE DE FACON ETANCHE LA CHAMBRE DE DECHARGE DU RACCORD D'INSPIRATION ET FERME L'ORIFICE DE L'ALESAGE DU CORPS SOUS L'EFFET DE LA PRESSION. IL EN RESULTE, OUTRE UNE DIMINUTION DE LA PRESSION NECESSAIRE A L'ACTIONNEMENT, UNE CONSTRUCTION PLUS SIMPLE ET PLUS COMPACTE DU SYSTEME.THIS VALVE SYSTEM INCLUDES, LIKE THE KNOWN SYSTEMS, A MAIN VALVE WITH A PISTON 5, THROUGH AN AXIAL BORE 19 MAKING A CLOSING CHAMBER 8 COMMUNICATE WITH A RESPIRATORY GAS INLET 4 CONNECTION, AND AN AUXILIARY VALVE CONTROLLED BY L 'ACTION ON A MEMBRANE OF THE PRESSURE THAT REIGNS IN THE INSPIRATION FITTING 13. IT IS CHARACTERIZED IN THAT THE AUXILIARY VALVE IS CONSTITUTED BY A BODY 9 FORMING A WALL OF THE CLOSING CHAMBER MOUNTED WATERTIGHT AND THROUGH A BORE 10 OPENING IN A DISCHARGE CHAMBER 12 IN COMMUNICATION WITH THE ATMOSPHERE (CHANNEL 15) AND THROUGH MEMBRANE 11, WHICH SELECTS THE DISCHARGE CHAMBER FROM THE INSPIRATION FITTING AND CLOSES THE BODY BALE ORIFICE UNDER THE EFFECT OF PRESSURE. THIS RESULTS, IN ADDITION TO A REDUCTION OF THE PRESSURE NECESSARY FOR ACTION, A SIMPLER AND COMPACT CONSTRUCTION OF THE SYSTEM.
