ESTRUCTURA DE FILTRADO, EN PARTICULAR FILTRO DE PARTICULAS PARA LOS GASES DE ESCAPE DE UN MOTOR DE COMBUSTION INTERNA Y CONDUCTO DE ESCAPE ASOCIADO.

摘要

The particle filter comprises primary and secondary filtration parts each with inlet and outlet faces interlinked by at least 3 lateral faces, and a linking joint between the faces. - The structure comprises - (1) primary and secondary parts(15A , 15B),each with an inlet face(21) and outlet face(23) interlinked by at least 3 lateral faces(24) ; 15A and 15B present respectively lateral primary and secondary lateral faces(24A, 24B) opposite each other; - (2) a linking joint(17) between 24A and 24B. - The primary face(24A) comprises a region(35A) of low adherence with (17) opposite a region of strong adherence(33B) with the joint(17) ; the region of low adherence is defined by part of the side(37) common to (24A) and (23). Characterised in that, in an adjacent zone to the common side, the region(35A) comprises a lateral side(41A) of divergent form extending to the common side(37). An INDEPENDENT CLAIM is also included for an exhaust line incorporating the filter described.
