Abstract
A high energy loss fluid control device includes a plurality of annularly-shaped discs stacked one upon another and a reciprocal plug in slidable contact with the discs. Each of the discs has an inner periphery, an outer periphery, and a plurality of flow passageways extending between an inlet and an outlet located at the inner and outer peripheries. Each of the flow passageways have a plurality of sections connected with right-angle turns. The sections alternate between extending in a circumferential direction and a radial direction. Each passageway has an expanding cross-sectional area but each section has a constant cross-sectional area. A first one of the sections is radially extending toward the inlet to cause fluid to act upon itself and expend energy by turbulent interaction. Immediately downstream of the first section, second one of the sections is radially extending toward the outlet. The second section is generally straight and of a length adequate to regain control of fluid velocity for true frictional losses. Additionally, a passages connects adjacent passageways at the downstream end of the second passage so that fluid in adjacent passageways interacts, further resolve…
