Abstract
Patente de Invenção: <B>''ELEMENTO DE TUBULAçãO PARA TUBULAçõES DE GáS DE ESCAPE DE AUTOMóVEIS''<D>. A presente invenção refere-se a um elemento de tubulação de metal para desligar vibrações de alta freq³ência em tubulações de gás de escape de motores de combustão interna de automóveis. Para melhorar o desligamento destas vibrações de alta freq³ência, o elemento de tubulação segundo a presente invenção consiste essencialmente de um fole curto de alta rigidez, inserido na tubulação de gás de escape, com forma de passo de parafuso ou com ondulações anelares, de uma camisa de malha colocada sobre a seção ondulada do fole com fecho devido à força e com fecho devido à forma.
