APPLICATION OF RICHARD FARGO TWO-STAGE SOLENOID VALVE ABSTRACT A two-stage solenoid valve uses a pair of stacked coaxial armatures in a cylindrical sleeve housing. A first armature is provided with a fluid sealing ring and is urged by a first spring to peripherally seal an adjacent internal fluid port in a valve base supporting a first end of the sleeve housing. The first armature is provided with a coaxial bore extending through the armature and coaxial with the fluid sealing ring to form a fluid channel. The second armature also has a coaxial bore extending therethrough with a resilient sealing member slideably retained within the bore. A second spring is arranged to urge the resilient sealing member against a first end of the bore in the second armature and to extend therefrom to a fixed plug in a second end of the cylindrical housing. The resilient sealing member cooperates with a fluid port defining an end of the coaxial bore in the first armature opposite the end of the first armature having the fluid sealing surface. A first and a second solenoid coil are coaxially stacked to surround the cylindrical sleeve housing adjacent to respective ones of the - 2 - first and second armatures. An energization of the second coil provides a first fluid path through the bore in the first armature while an energization of both coils provides a second fluid path directly through the fluid port in the valve base to provide a first and a second flow rate, respectively, through the valve.
