ABSTRACT:
A valve assembly for introducing exhaust gas into the intake manifold of an internal combustion engine, preferably, an electric exhaust gas recirculation valve assembly. The valve assembly includes an actuator having a centered solenoid assembly that reciprocates a floating valve mechanism to provide a substantially constant flow rate of exhaust gas regardless of the reciprocating direction of the floating valve mechanism. That is, the valve assembly delivers a gas flow rate that is substantially free of hysteresis because the valve assembly provide substantially the same exhaust gas flow rate for a given percentage of a pulse width modulated duty cycle when the floating valve mechanism is reciprocating in a valve opening direction or a valve closing direction.
