| 摘要 |
The invention relates to an exhaust gas system (10) and an exhaust gas valve (24) for controlling a volumetric flow rate of exhaust gas which should be fed back to an internal combustion engine (12), having a housing (36), which comprises an exhaust gas inlet (40), an exhaust gas outlet (42), and a return outlet (44), and an adjustable valve element (46), whereby the opening cross-sections of the exhaust gas outlet (42) and of the return outlet (44) can be changed, characterized in that the valve element (46) is arranged relative to the exhaust gas inlet (40), to the exhaust gas outlet (42), and to the return outlet (44) in such a way that the valve element (46) can take a first position in which the return outlet (44) is completely closed while the exhaust gas outlet (42) is completely open, and a second position in which the return outlet (44) is partially open while the exhaust gas outlet (42) is still completely open, and a third position in which the return outlet (44) is at least partially open while the exhaust gas outlet (42) is partially closed. |
