Abstract

CE DISPOSITIF ATTENUE LE BRUIT DE L'ECHAPPEMENT DE L'AIR DANS LES APPAREILS PNEUMATIQUES A PERCUSSIONS. UNE ENCEINTE, OU L'AIR S'ECHAPPANT DU CYLINDRE DE L'APPAREIL EST PREALABLEMENT DETENDU, EST FORMEE ENTRE LA PAROI EXTERIEURE DU CYLINDRE ET UNE ENVELOPPE, ENTOURANT LE CYLINDRE, DONT LE SOMMET EST SOLIDAIRE D'UN MANCHON MONTE COULISSANT SUR LA PARTIE SUPERIEURE DU CYLINDRE, AVEC UNE SUSPENSION ELASTIQUE. L'AIR DETENDU EST EVACUE A L'EXTERIEUR AU TRAVERS D'UN PASSAGE ANNULAIRE DE FAIBLE LARGEUR, DELIMITE PAR LA PAROI EXTERIEURE DU CYLINDRE ET LA PARTIE INFERIEURE RESSERREE DE L'ENVELOPPE. CETTE DISPOSITION EVITE LA FORMATION DE GIVRE DANS LE PASSAGE D'EVACUATION DE L'AIR A L'ATMOSPHERE.
