Abstract:
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.
