Abstract: An exhaust gas feed device for an internal combustion engine includes an exhaust gas recirculation duct comprising an end, an outlet, and an outflow cross-section. An air intake duct opens into the exhaust gas recirculation duct. A flow-guiding element is arranged in and at the end of the exhaust gas recirculation duct. An exhaust gas recirculation valve comprises a regulator body. The regulator body is configured to control the outflow cross-section. A valve seat is arranged at the outlet at the end of the exhaust gas recirculation duct in which the flow-guiding element is arranged. The valve seat is configured to limit the outflow cross-section of the exhaust gas recirculation duct.

Abstract: 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 bundle or the bypass channel. According to the invention, the exhaust gas valve has a movable closing organ that is resistant to bending, said organ being preferably embodied as a pivoting semi-flap that is fixed with a longitudinal side to a drive shaft that is arranged crosswise relative to the exhaust gas flow.
