Abstract

CE DISPOSITIF S'APPLIQUE AUX DIAPHRAGMES POSSEDANT UNE REGION CENTRALE REALISEE COMME CLAPET ET SERRES PAR LEUR BORD EXTERIEUR ENTRE DES PARTIES DU CORPS D'UNE SOUPAPE OU D'UN AUTRE ORGANE DE DISTRIBUTION. SELON L'INVENTION, LE CORPS DE SOUPAPE 6, 10, 12 EST REALISE DE MANIERE QUE L'ESPACE 7 RECEVANT LE DIAPHRAGME 23 OU 17 POSSEDE UNE SECTION DROITE CUNEIFORME ENTRE LES PARTIES DU CORPS DE SOUPAPE SERRANT LE DIAPHRAGME ENTRE ELLES ET LA REGION CENTRALE 1 OU 15 DU DIAPHRAGME. L'INVENTION EST NOTAMMENT APPLICABLE AUX DISTRIBUTEURS UTILISANT DES CLAPETS FORMES PAR DES DIAPHRAGMES A LA PLACE DE TIROIRS MOBILES EN TRANSLATION OU ROTATIFS.THIS DEVICE APPLIES TO DIAPHRAGMS WITH A CENTRAL REGION ACHIEVED AS A VALVE AND TIGHTENED BY THEIR EXTERIOR EDGE BETWEEN PARTS OF THE BODY OF A VALVE OR ANOTHER DISTRIBUTION BODY. ACCORDING TO THE INVENTION, THE VALVE BODY 6, 10, 12 IS DESIGNED SO THAT THE SPACE 7 RECEIVING THE DIAPHRAGM 23 OR 17 HAS A CUNEIFORM STRAIGHT SECTION BETWEEN THE PARTS OF THE VALVE BODY CLAMPING THE DIAPHRAGM BETWEEN THEM AND THE CENTRAL REGION 1 OR 15 DIAPHRAGM. THE INVENTION IS IN PARTICULAR APPLICABLE TO DISTRIBUTORS USING VALVES SHAPED BY DIAPHRAGMS IN PLACE OF MOBILE DRAWERS IN TRANSLATION OR ROTATING.
