Abstract
A fluid pressure reduction device comprises a plurality of stacked disks having a perimeter and a hollow center aligned along a longitudinal axis. Each disk has at least one flow path extending between the hollow center and the perimeter, the flow path including an inlet section, an outlet section, and an intermediate section extending between the inlet and outlet sections. Each flow path intermediate section includes a pressure reducing structure and a recovery zone positioned immediately downstream of the pressure reducing structure.

37. A fluid pressure reduction device comprising:
-
a plurality of stacked disks having a thickness and defining a perimeter and a hollow center aligned along a longitudinal axis;
each disk having at least one flow path extending between the hollow center and the perimeter, the flow path including an inlet section, an outlet section, and an intermediate section extending between the inlet and outlet sections;
wherein each flow path extends across the entire thickness of the disk to provide a through-cut flow path, each through-cut flow path dividing the disk into at least first and second blank portions. - View Dependent Claims (38, 39, 40, 41, 42, 43, 44, 45, 46, 47)
