Abstract
A valve having stacked disks with alternate circular grooves in the faces thereof to provide a high pressure drop surface in fluid flow transverse to said grooves and ridges. The disks are circular in shape with a circular center opening to provide a central fluid opening when the disks are stacked with the center openings in register. Fluid enters the center opening and flows radially between the adjacent faces of a pair of disks to flow transversely across the continuous circular grooves and ridges.

12. 5. A valve for high pressure fluids comprising:
-
a valve housing; a plunger; and a plurality of stacked annular disks mounted within said housing, each said disk comprising; an annular center opening in register with the annular center openings of the remaining disks, said annular center openings together providing a cylindrical cavity that accommodates reciprocating movement of said plunger so as to control the flow of fluid through said stacked disks; a plurality of substantially circular ridges on at least one face of each said disk and a plurality of mating circular grooves on the opposite face of an adjacent disk, the depth of said grooves increasing from the innermost to the outermost groove and the height of said ridges increasing from the innermost to the outermost ridge; a plurality of projections on at least one face of each said disk, said projections overlapping the rim of an adjacent disk in order to prevent lateral movement thereof, said projections also spacing the disk from an adjacent disk so as to permit fluid flow therebetween; a first substantial opening about the inside periphery of each disk, said first opening communicating with the space between said disk and an adjacent disk; and a second substantial opening about the outside periphery of each said disk, said second opening communicating with (1) the space between said disk and an adjacent disk and (2) a discharge outlet of said valve. .Iaddend.
