  • FORCE BALANCED LINEAR SOLENOID VALVES
    Publication number: 20080168968
    Abstract: An electronic exhaust gas recirculation valve for an internal combustion engine selectably provides a recirculation path from engine exhaust to engine intake. A main spring biases the valve in a closed position. The main spring acts on a main spring receiving surface rigidly fixed to a pintle that operates the valve. A solenoid armature is biased against a surface rigidly fixed to the pintle by a spring acting between the pintle and the armature. The armature is permitted to move radially with respect to the pintle for alignment compensation. The main spring force does not affect frictional forces between the armature and the pintle.
