A variable flow venturi assembly for use in an exhaust gas recirculation system of an internal combustion engine having a housing with an inner chamber, a combustion air inlet in communication with the inner chamber, and an exhaust gas inlet in communication with the inner chamber. A venturi valve is slidably disposed within the chamber. A venturi valve has a longitudinally extending throughhole with an inlet opening in communication with the combustion air inlet, an outlet opening and a venturi section interposed and in communication with each of the inlet opening and the outlet opening. The venturi valve further has at least one bypass port and at least one induction port. Each bypass port is in communication with a combustion air inlet and a throughhole. Each induction port is in communication with the exhaust gas inlet and the throughhole. An actuator slidably moves the venturi valve within the inner chamber of the housing.
