Abstract
Patente de Invenção: <B>''ELEMENTO DE DESACOPLAMENTO PARA IMPEDIR A PROPAGAçãO DE VIBRAçõES''<D>. A presente invenção sugere um elemento de desacoplamento para evitar a propagação de vibrações numa tubulação de gás de escape de um motor de combustão interna, com um fole metálico em forma de passo de rosca ou com ondulações anelares, que é inserido entre uma primeira parte de tubulação, disposta a montante, e uma segunda parte de tubulação, disposta a jusante. Para unir um bom efeito de desacoplamento com montagem e conserto fáceis, o elemento de desacoplamento é executado de tal modo que a primeira parte da tubulação, disposta a montante, na seção de sua extremidade a ser ligada ao fole, possui um reforço anelar, que a primeira parte da tubulação, a jusante do reforço anelar, contínua num tubo de chama que se estende para dentro do fole, sem contato com as ondulações internas do fole, que na seção de transição entre reforço anelar e tubo de chama é prevista uma superfície de centragem e que o fole, no reforço anelar, é conectado de modo separável, com a primeira parte da tubulação por meio de um acoplamento de aperto, enquanto encosta na superfície de centragem.
