Claim:
An exhaust gas recirculation (EGR) valve assembly comprising: a housing defining a portion of a first passage through to a main outlet, a portion of a second passage that communicates exhaust gas flow out a cooler outlet to a cooler for controlling a temperature of exhaust gases, and a third passage that receives exhaust gas flow from the cooler and communicates the exhaust gas flow from the cooler to the first passages for flow through the main outlet; a first EGR valve mounted within the housing for controlling exhaust gas flow through the first passage; a second EGR valve mounted within the same housing as the first EGR valve, the second EGR valve controlling exhaust gas flow through the second passage and out the cooler outlet to the cooler, wherein the second passage communicates exhaust gas received from the cooler to the first passage and the main outlet to an intake manifold.
