Exhaust gas recirculating means for reducing the pollutants discharged from an internal combustion engine by regulating the flow of a portion of the exhaust gases from the exhaust manifold to the intake manifold by the use of plate valve means that precisely meters the flow of exhaust gases and/or ambient air in response to atmospheric pressure, intake manifold pressure and exhaust manifold pressure. In one form a single plate valve is provided in an improved exhaust gas recirculating valve, whereas in a second form, dual plate valves are used. Included with the ambient air and exhaust gas recirculating means is a velocity nozzle means for introducing the gases into the intake manifold and for helping to scavenge the PCV system's crank case emissions.
