ABSTRACT:
A proportional variable force solenoid control valve with an armature reciprocably movable within the bore hole of a coreless solenoid bobbin in proportion to applied electrical current between positions corresponding to a closed valve position and a fully open position. The positioning of the armature is controlled by balancing the variable force of the magnetic field of the coreless solenoid plus the force of the magnetic field of a permanent ring magnet against the force of a coil spring which biases the valve toward the closed position. The armature is suspended by low spring rate plate springs on opposite ends of the armature. An elastomeric diaphragm seals the solenoid against contaminants. The force of the coil spring is adjusted by a threaded plug.
