Filtering structure, especially particle filter for exhaust gases of an internal combustion engine, and associated exhaust line
摘要：
This structure comprises first and second filtering elements (15A, 15B) which are respectively provided with a first and a second face (24A, 24B) arranged opposite each other and a seal (17) connecting said faces (24A, 24B). The first face (24A) comprises at least a first region (35A) that does not adhere, or only slightly adheres to said seal (17), opposite a first region (33B) that strongly adheres to said seal (17) of the second face (24B). The first region (35A) that does not adhere or only slightly adheres is delimited by at least a portion of the edge (37) common to the first face (24A) and a discharge face (23). The first region (35A) that does not adhere or only slightly adheres comprises a side (41A) that diverges towards the discharge face (23) and which extends up to said common edge (37).
