Abstract
An EEGR valve has a solenoid with an armature supported at each end on circular disks. These disks are fixed to the top and bottom having numerous penetrations (e.g., slots, slits or openings) to permit the disks to be deflected upward or downward. The penetrations are arranged such that when a current is applied to the solenoid coil the armature deflects the disks and permits the armature to move up and down within the coil. The penetrations are arranged as concentric rings of penetrations. The disks are fixed at several locations around their edges to the stator of the solenoid. In this manner, the armature moves back and forth along its axis and not laterally, thus permitting the stator to be located quite close to the armature without wearing against the stator, A spring is provided to preload the armature and deflect the disks in a concave shape different from their unloaded and substantially flat configuration. In this manner, the coil can drive the solenoid.
