The present invention is an exhaust gas recirculation (EGR) valve for an
engine having an exhaust gas recirculation cooler operable for receiving
exhaust gas from an exhaust, and delivering the exhaust gas to an intake.
The present invention also includes an exhaust gas recirculation bypass
passage operable for receiving exhaust gas from an exhaust, bypassing the
exhaust gas recirculation cooler, and delivering the exhaust gas to an
intake, as well as a single valve operably associated with the exhaust
gas recirculation cooler and the exhaust gas recirculation bypass
passage. The single valve is selectively operable for opening or closing
flow from the exhaust to the exhaust gas recirculation cooler, the
exhaust gas recirculation bypass passage, or both, the single valve also
operable for metering flow therebetween.
