ABSTRACT:
A transducer modifies a subatmospheric pressure signal to create an operating pressure which positions an exhaust gas recirculation control valve. A regulating unit senses subatmospheric induction passage pressure to provide the pressure signal and prevents the pressure signal from dropping below a lower limit to thereby establish the maximum exhaust gas recirculation area produced by the control valve.
