Abstract
A spool valve assembly, configured to control the flow of fluid, includes a spool valve, configured to move axially along an axis to control fluid flow, having a spool cavity and a plurality of spool apertures that communicate fluid between the spool cavity and an outside surface of the spool valve; a valve sleeve, in which the spool valve is concentrically positioned, that slidably receives the spool valve; and a valve plug, received within the spool cavity, having at least one plug aperture and a plug cavity, wherein the spool apertures at least partially overlap the plug aperture(s) in a radial direction to permit the flow of fluid between the plug cavity and the outside surface within a defined flow rate variance regardless of the angular position of the valve plug relative to the angular position of the spool valve.
