Abstract
A fluid pressure reduction device with tortuous flow paths in stacked disks. The fluid flow outlets are maintained independent by directed flow paths to avoid flow collisions in the exiting flow streams. A flow straightening section includes an inwardly tapered end section at the fluid flow outlets. Splitting of a tortuous flow path into at least two sub-flow paths with balancing of the mass flow between the sub-flow paths.
