Abstract
In a system for delivering air from an air pump to the exhaust system of an internal combustion engine, an air diverter valve assembly has a regulating control responsive to air pump discharge pressure which positions the diverter valve member to divert excess air flow away from the exhaust system when the pressure exceeds a selected value. The assembly also has a timed anti-backfire provision effective to override the regulating control and divert all air flow to the atmosphere upon a sudden decrease in induction manifold pressure.
