Abstract
A solenoid actuated valve for controlling flow of fluid through a bore defined by a tube comprises an armature fitted slidably in the bore for displacement therein under solenoid control. The armature comprises a generally cylindrical magnetic body that is a clearance fit in the bore, and a glide pad carried by the magnetic body for guiding movement of the magnetic body relative to the tube and preventing direct sliding contact therebetween.
