Abstract
A solenoid control valve for use in adaptive braking systems has a unique armature for reducing the operating times of the valve. When the solenoid is energized, the armature moves towards a plunger mechanism which operates to open a ball valve in the inlet of the solenoid control valve. When the solenoid is de-energized, a first spring bias means operates to close the ball valve stopping the flow of the fluid from the source to a hydraulic means. The unique armature has at least one axially extending passageway from one end surface to the other and in addition has a circular groove intersecting the passageway on the top surface of the armature abutting the plunger to provide a relief means to reduce surface adhesion.
