  • Patent number: 6135415
    Abstract: The present invention provides an exhaust gas recirculation assembly. The exhaust gas recirculation assembly includes a single housing having an integrated airflow passage, a recirculated exhaust gas passage, and valve mechanism. The airflow passage is operatively positioned to allow continued flow of air through a throttle body and an intake manifold of an air induction system. The valve mechanism is disposed within the exhaust gas recirculation passage and controls the flow of recirculated exhaust gas through the recirculated exhaust gas passage into the airflow passage. The valve mechanism, preferably, comprises a butterfly valve. An electric actuator, which is also integrated into the housing, operates the valve mechanism.
