STRUCTURE DE FILTRATION, NOTAMMENT FILTRE A PARTICULES POUR LES GAZ D'ECHAPPEMENT D'UN MOTEUR A COMBUSTION INTERNE.

摘要

The structure comprises at least first and second filter members ( 15 A, 15 B) respectively provided with first and second faces ( 24 A, 24 B) placed facing each other, and a joint ( 17 ) interconnecting said faces and extending between said faces ( 24 A, 24 B). The first face ( 24 A) comprises at least one region ( 33 A) of strong adhesion with said joint ( 17 ) and at least a region ( 35 A) of weak or no adhesion with the joint ( 17 ). These regions ( 33 A, 35 A) are located respectively facing a region ( 35 B) of the second face ( 24 B) presenting weak or no adhesion with said joint ( 17 ), and a region ( 35 B) of the second face ( 24 B) presenting strong adhesion with said joint ( 17 ). The structure is applicable to particle filters for the exhaust gas from an internal combustion engine.
