Abstract
Disclosed is a exhaust gas recirculation valve including a motor turning a shaft, a cam disposed on the shaft, the cam having a profile, and a valve assembly including a seat and a pintle. The pintle is disposed for reciprocal movement with respect to the valve for permitting and prohibiting delivery of exhaust gas through the valve assembly. The pintle is also in contact with the profile of the cam such that constant angular motion of the torque output shaft is converted to non-linear motion of the pintle.
