Abstract: A solenoid valve and method has a simplified structure that integrates the fluid metering functions of the spool in the armature, thereby eliminating the need for a separate spool, bearings, and pin in the valve. The armature has a aperture that communicates with at least one port in a valve body. The position of the differential in the armature with respect to the ports in the valve body controls the pressure of fluid exiting the outputs of the valve body. In one embodiment, the same overall valve structure can be modified to form both inversely proportional valves and directly proportional valves. By integrating the fluid metering functions of the spool into a single ported armature, the inventive valve assembly reduces the number of parts in the valve, simplifying construction.
