ABSTRACT:
In an emission control system having an air pump for delivering air to the exhaust system of an internal combustion engine, a valve controls the air pump discharge pressure in a fixed relationship to exhaust pressure by diverting a portion of the air pump discharge air flow. As a result, the flow of air from the pump to the exhaust system is maintained as a constant proportion of the engine air flow.
