Motor vehicle exhaust-gas recirculation valve arrangement

摘要

A motor vehicle exhaust gas recirculation valve arrangement for an exhaust gas recirculation system of an internal combustion engine includes an electric drive motor, an intermediate shaft, an eccentric shaft, and a valve drive. The electric drive motor comprises a motor shaft and a motor pinion. The intermediate shaft comprises an intermediate shaft pinion and an output gear. The output gear is configured to mesh with the motor pinion. The eccentric shaft comprises an eccentric and a drive gear. The drive gear is configured to mesh with the intermediate shaft pinion. A valve drive comprises a valve plate, a valve rod, and a link. The link is configured to have the eccentric engage therein. The intermediate shaft is arranged laterally beside the eccentric shaft so that the eccentric and the link lie beside the drive motor.
