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.

1. An exhaust gas feed device for an internal combustion engine, the exhaust gas feed device comprising: an exhaust gas recirculation duct comprising an end, an outlet, and an outflow cross-section;an air intake duct into which the exhaust gas recirculation duct opens;a flow-guiding element provided as a swirl generator, the flow-guiding element being arranged in and at the end of the exhaust gas recirculation duct;an exhaust gas recirculation valve comprising a regulator body, the regulator body being configured to control the outflow cross-section; anda valve seat arranged at the outlet at the end of the exhaust gas recirculation duct in which the flow-guiding element is arranged, the valve seat being configured to limit the outflow cross-section of the exhaust gas recirculation duct,wherein, the end of the exhaust gas recirculation duct, in which the flow-guiding element is arranged, is arranged to taper in a frustoconical shape towards the outlet,the exhaust gas recirculation duct further comprises a surrounding side wall arranged at the end, andthe swirl generator comprises vanes arranged to extend radially towards the surrounding side wall of the exhaust recirculation duct and a central axle to which the vanes are fastened, the vanes comprising an angle to the central axle which increases in a circumferential direction, as seen in a flow direction of an exhaust gas, and being configured to extend to the surrounding side wall of the exhaust gas recirculation duct. 2. The exhaust gas feed device as recited in claim 1, wherein the air intake duct comprises a flow cross section, andthe outflow cross section of the exhaust gas recirculation duct includes an angle which is between 30° and 90° with the flow cross section of the air intake duct. 3. The exhaust gas feed device as recited in claim 1, wherein the regulator body is an eccentrically supported flap comprising a rotary axis which is arranged upstream with respect to a flow direction of an exhaust gas through the outflow cross section of the exhaust gas recirculation duct. 4. The exhaust gas feed device as recited in claim 1, wherein, the air intake duct comprises a housing which comprises an opening,and further comprising a duct section which is inserted into the opening of the housing,wherein, the swirl generator is fastened inside the duct section so that the swirl generator and the duct section are each inserted into the opening of the housing of the air intake duct. 5. The exhaust gas feed device as recited in claim 4, wherein the swirl generator is configured to be integral with the duct section. 6. An exhaust gas feed device for an internal combustion engine, the exhaust gas feed device comprising: an exhaust gas recirculation duct comprising an end, a surrounding side wall arranged at the end, an outlet, and an outflow cross-section, the surrounding side wall being non-permeable;an air intake duct into which the exhaust gas recirculation duct opens;a flow-guiding element provided as a swirl generator, the flow-guiding element being arranged in and at the end of the exhaust gas recirculation duct;an exhaust gas recirculation valve comprising a regulator body, the regulator body being configured to control the outflow cross-section; anda valve seat arranged at the outlet at the end of the exhaust gas recirculation duct in which the flow-guiding element is arranged, the valve seat being configured to limit the outflow cross-section of the exhaust gas recirculation duct,wherein,the end of the exhaust gas recirculation duct, in which the flow-guiding element is arranged, comprises solid walls is arranged to taper in a frustoconical shape towards the outlet,the exhaust gas recirculation duct further comprises a surrounding side wall arranged at the end, andthe swirl generator comprises vanes arranged to extend radially towards the surrounding side wall of the exhaust recirculation duct and a central axle to which the vanes are fastened, the vanes comprising an angle to the central axle which increases in a circumferential direction, as seen in a flow direction of an exhaust gas, and being configured to extend to the surrounding side wall of the exhaust gas recirculation duct.
