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. The discs form a plurality of flow passageways extending between an inlet and an outlet located at the inner and outer peripheries of the discs. Each of the flow passageways has a plurality of sections connected with right-angle turns. 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, a 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 by true frictional losses. The passageways can be formed by stacks of discs that cooperate to fully define intermediate passageways or by alternating flow-path discs and separator discs that cooperate to form the passageways.

[ What is claimed is:] [1.] A disc stack for a high energy loss fluid control device, said disc stack comprising a plurality of annularly-shaped discs stacked one upon another, each of said annularly-shaped discs having an inner periphery and an outer periphery, said discs cooperating to form a plurality of passageways each extending between an inlet and an outlet located at said inner and outer peripheries of said discs, each of said passageways having a plurality of sections connected with right-angle turns with said sections alternating between extending in a circumferential direction and extending in a radial direction, wherein a first one of said sections is radially extending toward said inlet to cause fluid to act upon itself and expend energy by turbulent interaction, and a second one of said sections which is the next radially extending section downstream of said first one of said sections is generally straight and has a length which is greater than a length of said first one of said sections to gain control of fluid velocity by frictional losses.
