Abstract
An exhaust gas recirculating valve with vacuum motor actuator is integrally combined with an electronic control system having a valve position sensor and an electrically controlled pilot valve for the vacuum motor. The electronic control system responds directly to an externally generated low power voltage signal so that the voltage signal and the valve position are related in a monotonic manner. A signal circuit indicates when the exhaust gas recirculating valve is under command of the externally generated low power voltage signal.
