ABSTRACT:
An exhaust gas recirculation valve construction and method of making the same are provided, the valve construction comprising a housing provided with an inlet and an outlet separated by a valve seat, a movable valve member carried by the housing for opening and closing the valve seat and an electrically operated stepper motor carried by the housing and being operatively interconnected to the valve member for positioning the valve member relative to the valve seat. The valve member and the valve seat are arranged so as to be reverse acting and a spring is operatively interconnected to the valve member to tend to move the valve member to its closed position with the valve seat upon loss of electrical current to the motor.
