The invention relates to an exhaust gas heat exchanger comprising a bundle of pipes consisting of exhaust gas pipes and a bypass channel in a common housing. The pipe bundle is arranged in a first chamber that is crossflown by a liquid coolant and the bypass channel is arranged in a second, separate chamber. The pipe bundle and the by pass channel lead into a common exhaust gas inlet area and a common exhaust gas outlet area in which an exhaust gas valve actuated by a servo-drive is arranged, said valve guiding the exhaust gas flow through the pipe bundl...
The invention claimed is: 1. An exhaust gas heat exchanger comprising: a housing, a tube bundle composed of exhaust-gas tubes positioned in said housing, a cooling circuit for circulating a coolant fluid around the exhaust gas tubes, a bypass passage located in said housing, wherein the tube bundle and the bypass passage open into a common exhaust gas inlet region and also in a common exhaust gas outlet region, a selectively actuatable exhaust gas valve comprising a moveable closure member arranged in either the inlet region or the outlet region for gui...
