Abstract
The invention relates to an exhaust gas recirculation device () for an internal combustion engine, in particular in a motor vehicle, having an exhaust gas recirculation line () for introducing exhaust gas into a primary intake line (), with an exhaust gas recirculation valve () for controlling the exhaust gas recirculation line (). The exhaust gas recirculation line () has an end section () which runs into the primary intake line () with an orifice opening (). In order to improve the reliability of the exhaust gas recirculation device (), the exhaust gas recirculation valve () has a sleeve () arranged in the fresh air line (), said sleeve () enclosing the exhaust gas recirculation line () in the region of the orifice opening (), being mounted in the fresh air line () so as to be axially adjustable, and presenting a radial internal nozzle contour () with a flow cross section which first decreases and then increases in size in the flow direction, the exhaust gas recirculation valve () having an actuating device () for axially adjusting the sleeve () relative to the primary intake line.
