The invention relates to an exhaust-gas recirculation device for recirculating exhaust gas into the gas supply of engines, in particular motor vehicle engines. Said device comprises an exhaust-gas supply (2), a fresh-gas supply (14) and an outlet channel (16) that opens into the gas supply. At least the exhaust-gas supply (2) and the fresh-gas supply (14) are interconnected via a control organ (4) for apportioning the exhaust gas. A pressure plate (8; 30; 50; 70;) is provided on the side of the control organ (4) facing the fresh-gas supply (14), said plate consisting of a base plate (32; 52; 72; 82) with gas passage zones (10; 40; 62) and at least one pivoting plate (34; 54; 74) that is mounted on the base plate so that it can rotate or pivot. Said pressure plate effects a pretension or retaining force, in particular in the form of a spring force (90), between the base plate and the pivoting plate, in order to cover the gas passage zones by bringing the pivoting plate to rest against the base plate. |
