ABSTRACT:
A solenoid operated valve with the armature disposed within the coil axially between first and second flux collectors. A flux director surrounding the armature has annular portions thereof contracting one of the flux collectors and has a plurality of fingers spaced circumferentially about the annular portion and extending inwardly toward the armature to increase and distribute the flux thereto for minimizing magnetic side loading due to eccentricity.
