Abstract

L'invention concerne un marteau brise-béton silencieux. On isole phonétiquement les bruits mécaniques par des parois isolantes 7 et 8. On réalise un silencieux d'échappement d'air en créant deux chambres annulaires concentriques 20 et 25 autour du cylindre du marteau. Un canal de transfert 21 régularise le débit à l'échappement. Enfin, l'outil est monté sur un silent-block 41. Application : installation de chantier associant un compresseur et un marteau silencieux.
