Abstract
A control valve for use in a variable assist power steering system of a vehicle having a valve element disposed within a valve chamber formed in a valve housing. The valve element is connected by a coupling to a proportional solenoid which is mounted upon the valve housing The solenoid includes an axially movable armature which is connected by a coupling to the valve element. The coupling transfers axial movement of the solenoid armature to the valve element. The coupling also is operable to minimize the transfer of transverse movement of the solenoid armature to the valve element.
