Abstract

CE SILENCIEUX EST DESTINE A AMORTIR LES BRUITS PRODUITS PAR L'ECHAPPEMENT A L'EXTERIEUR D'AIR COMPRIME ET IL COMPREND UN CORPS CREUX POURVU D'AU MOINS UNE ADMISSION DANS UNE PREMIERE PAROI D'EXTREMITE ET CONTENANT UN MATERIAU D'INSONORISATION. L'ADMISSION 2 EST SUIVIE D'UNE CHAMBRE D'EXPANSION 5 SITUEE DANS LE CORPS 1 ET DELIMITEE PAR LE MATERIAU D'INSONORISATION 3. AU MOINS UN PASSAGE 4 TRAVERSE LE MATERIAU D'INSONORISATION 3 SENSIBLEMENT DANS LE SENS DE LA LONGUEUR DU CORPS 1 ET RELIE LA CHAMBRE D'EXPANSION 5 A AU MOINS UNE SORTIE 12 DANS UNE DEUXIEME PAROI D'EXTREMITE OPPOSEE A LA PREMIERE. LES PASSAGES 4 DANS LE MATERIAU D'INSONORISATION 3 SONT DISPOSES DE MANIERE QUE LEURS EXTREMITES DIRIGEES VERS L'ADMISSION 2 SOIENT DECALEES PAR RAPPORT A CELLE-CI.THIS MUFFLER IS INTENDED TO DAMAGE THE NOISE PRODUCED BY THE EXHAUST TO THE EXTERIOR OF COMPRESSED AIR AND IT INCLUDES A HOLLOW BODY PROVIDED WITH AT LEAST ONE ADMISSION IN A FIRST END WALL AND CONTAINING SOUNDPROOFING MATERIAL. ADMISSION 2 IS FOLLOWED BY AN EXPANSION CHAMBER 5 LOCATED IN BODY 1 AND BOUNDARED BY THE SOUNDPROOFING MATERIAL 3. AT LEAST ONE PASSAGE 4 CROSSES THE SOUNDPROOFING MATERIAL 3 SENSITIVELY IN THE LENGTH OF THE BODY 1 AND CONNECTS THE EXPANSION CHAMBER 5 TO AT LEAST ONE EXIT 12 IN A SECOND END WALL OPPOSED TO THE FIRST. THE PASSAGES 4 IN THE SOUNDPROOFING MATERIAL 3 ARE ARRANGED SO THAT THEIR ENDS DIRECTED TOWARDS THE INLET 2 ARE OFFSET WITH RESPECT TO THE latter.
