Claim Text:
1. An exhaust gas treatment unit, comprising: a housing having first and second mutually oppositely disposed ends; a tube extending from said first end to said second end as an inflow region for an exhaust gas; a deflecting region next to said second end for deflecting the exhaust gas; and a return flow region extending between said tube and said housing; said tube having an outlet region, adjacent said second end, from which a first partial exhaust gas flow flows into said deflecting region; and said tube having at least one lateral opening in said deflecting region upstream of said outlet region, causing said first partial exhaust gas flow to collide in said deflecting region with at least one second partial exhaust gas flow flowing out of said at least one opening, said at least one opening defining a downstream boundary of said at least one opening in an exhaust gas flow direction; said at least one opening having at least one baffle element configured to deflect said at least one second partial exhaust gas flow out of said tube and into said deflecting region; said at least one baffle element being punched out and bent over at said downstream boundary from a wall of said tube into said inflow region and said at least one baffle element extending at an angle in an upstream direction for directing said at least one second partial exhaust gas flow into said deflecting region.
