| 摘要 |
The invention relates to a valve (1) for regulating the flow of EGR gases in a loop allowing a proportion of the exhaust gases leaving a vehicle combustion engine to be bled off, having a body delimiting an internal duct (2) and comprising a shutter (3) pivot-mounted on an axle (4) dividing said flap (3) into a first part (5) and a second part (6), said flap (3) being able to pivot between an open position that allows gases to pass into the duct (2) and a closed position that prevents said passage, and for which out of the first (5) and second (6) parts, at least one comes into abutment against a support element (7). The first part (5) of the flap has a thickening (9) so as to reduce the passage section for gases between said first part (5) and the support element (7), for angles of opening of said flap (3) that are below a threshold value. |
