Abstract

Patente de Invenção: <B>"ELEMENTO CONDUTOR COM AMORTECIMENTO, PARTICULARMENTE PARA TUBULAçõES DE GáS DE DESCARGA DE MOTORES DE COMBUSTãO INTERNA EM AUTOMóVEIS"<D>. Um elemento condutor, particularmente para tubulações de gás de descarga de motores de combustão interna em automóveis, com um fole em forma de passo de parafuso ou ondulado anularmente, dotado de extremidades de ligação cilíndricas, e uma malha metálica que circunda diretamente o fole, distingue-se pelo fato de qua a malha metálica tem estabilidade própria e apresenta pelo menos uma deformação plástica, para amortecimento acústico ou mecânico do fole. A malha metálica tem, desse modo, tanto uma função de proteção como também de amortecimento.
