Abstract

An exhaust gas recirculation device for an internal combustion engine, in particular in a motor vehicle, includes a recirculation line and a fresh gas line section. A Venturi nozzle is designed in an inlet area of the fresh gas line section. The recirculation line opens into the fresh gas line section in a low pressure area of the Venturi nozzle. The Venturi nozzle has a variable flow cross section to allow exhaust gas recirculation in the largest possible operating range of the internal combustion engine.
