Abstract

"ESTRUTURA DE FILTRAGEM E LINHA DE ESCAPAMENTO". A presente invenção trata de uma estrutura que compreende um primeiro e um segundo meios de filtragem (15A, 15B) que apresentam respectivamente uma primeira e uma segunda faces (24A, 24B) dispostas uma diante da outra, e uma junta (17) de ligação das referidas faces (24A, 24B). A primeira face (24A) compreende pelo menos uma primeira região (35A) de aderência baixa ou nula com a referida junta (17), situada diante de uma primeira região (33B) de aderência forte com a referida junta (17) da segunda face (24B). A primeira região (35A) de aderência fraca ou nula é delimitada por pelo menos uma parte da aresta comum (37) à primeira face (24A) e a uma face de escape (23). A primeira região (35A) de aderência baixa ou nula compreende uma borda lateral (41) de forma divergente em direção à face de escape (23) e que se estende até a referida aresta comum (37). A presente invenção pode ser aplicada aos filtros de partículas para os gases de escapamento de um motor.
