摘要

The exhaust gas recycling system (1) for an internal combustion engine (11) has an exhaust system (2) and an intake pipe (3) and an exhaust turbocharger (4) having a turbine (4') in the exhaust line and a compressor (4''). The exhaust is fed through a return feed (5) having a first throttle body (6), and a second throttle body (7) adjustable with the first throttle body in the direction of flow of the exhaust behind the return feed. A first throttle body has a spring element (8) provided against the flow direction of the compressed exhaust flap valve.
