Patent ID: 7503170

Claim:
A longitudinally extending structure ( 11 ; 101 ; 201 ; 301 ; 401 ; 501 ; 601 ) for filtering the exhaust gases from an internal-combustion engine, of the type comprising at least one filtering member ( 21 ) comprising: intake conduits ( 35 ) for the gases to be filtered, into which respective gas intake openings ( 47 ) emerge, at least some of the intake conduits ( 35 ) emerging through openings ( 49 ; 607 ) for discharging respective residues provided downstream of the respective intake openings ( 47 ); extracting conduits ( 37 ) for extracting filtered gases emerging into respective openings ( 55 , 63 ; 602 ) for extracting filtered gases, the extracting conduits ( 37 ) being separated from the intake conduits ( 35 ) by porous filtering walls ( 43 ); characterized in that the residue discharge openings ( 49 ; 607 ) of at least one group of intake conduits ( 35 ) open into at least one common manifold ( 25 ) for receiving solid filtered residues forming counter-pressure means for said group of intake conduits ( 35 ), this manifold ( 25 ) being isolated from the extracting conduits ( 37 ), in that at least some of the openings ( 55 , 63 ) for extracting filtered gases and/or at least some of the residue discharge openings ( 607 ) emerge transversely into the filtering member ( 21 ), in that the filtering member ( 21 ) comprises rows ( 39 ) of adjacent intake conduits ( 35 ) and rows ( 41 ) of adjacent extracting conduits ( 37 ), and in that said intake and extracting conduits extend along axes substantially parallel to a longitudinal axis (X-X′) of said structure.
