ABSTRACT:
A solenoid-operated control valve for a variable assist power steering system of an automobile vehicle includes a valve structure which defines a variable flow orifice in response to a predetermined variable (e.g., vehicle velocity) thereby providing fluid pressure needed to modify user input torque supplied to the steering wheel. The valve structure features a unique nonmagnetic core tube which reduces manufacture costs, enhances the ease of assembly of the magnetic housing elements needed to complete a magnetic circuit, and ensures the armature responds as needed to control orifice closure.
