ABSTRACT:
A proportional solenoid-driven valve control assembly contains a moveable, magnetic armature positioned adjacent to one end of a fixed pole piece that protrudes from a solenoid bore and is supported by means of a compact suspension spring arrangement adjacent to the one end of the bore. The movable armature is configured to provide two radial magnetic flux paths. One flux path traverses a fixed radial shunt gap at one end of fixed magnetic pole piece that is located in and protrudes from the one end of the solenoid bore. The other flux path traverses a variable geometry reluctance gap defined between a radially projecting, tapered rim portion of the armature and an inwardly projecting tapered portion of the solenoid assembly housing. The proportional solenoid assembly is mechanically coupled with a valve unit for electrically controlling its operation, in particular the flow of fluid between a fluid input port and a fluid exit port of the valve unit, in accordance with displacement of the movable armature along the solenoid assembly axis in proportion to the current applied to the solenoid.
