1. A fluid pressure reduction device comprising:
- a plurality of stacked disks having a perimeter and a hollow center aligned along a longitudinal axis; and
each disk having at least a first and a second flow path, each flow path having a generally spiral shape and continuously extending between the hollow center and the perimeter wherein at least the first and second flow paths spiral in generally opposite directions and the opposing walls of each flow path gradually diverge, each flow path being further comprised of an inlet section, an outlet section, and an intermediate section extending between the inlet and outlet sections;
wherein each flow path crosses at least one other flow path at at least one intersection; and
wherein each of the flow path intermediate sections includes a recovery zone downstream of the intersection.

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.

6. A fluid pressure reduction device comprising:
-
a plurality of stacked disks having a perimeter and a hollow center aligned along a longitudinal axis; and
the plurality of stacked disks defining 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 having a generally spiral shape and extending between the inlet and outlet sections, the flow path including a pressure reducing structure and a recovery zone positioned immediately downstream of the pressure reducing structure;
wherein a first disk of the plurality of stacked disks includes the inlet section and an upstream portion of the intermediate section, and a second disk of the plurality of stacked disks located adjacent the first disk includes the outlet section and a downstream portion of the intermediate section, the intermediate section upstream portion fluidly communicating with the intermediate section downstream portion.
