Abstract
A proportional solenoid-driven valve control assembly contains a moveable, magnetic armature positioned adjacent to one end of a fixed magnetic pole piece. The magnetic pole piece has a longitudinal axial pole piece portion, and a relatively thin, annular axial pole piece portion, that rapidly saturates, and is effectively mechanically solid with the longitudinal pole piece portion for fluid leakage containment. A radial portion is solid with the annular axial portion and provides support and alignment for the armature relative to the magnetic pole piece, without the need for non-magnetic material for alignment, support or magnetic flux flow path control.
