ABSTRACT:
An exhaust gas recirculation valve comprising a solenoid device and a valve mechanism is disclosed. The solenoid device has a coil, an armature, and a roller bearing to support a guide mechanically coupled to the armature. The armature and the guide translate with respect to the roller bearing in response to energizing the solenoid device by applying an electrical signal to the coil. The valve mechanism has a stem member which translates with the stem guide for varying fluidic communication between an inlet port and an outlet port in response to the electrical signal.
