ABSTRACT:
Fluid pressure reducing apparatus adapted for positioned placement in a fluid valve or conduit in which pressure reduction is to be effected. A disc, sleeve or other body member in the flow path defines a plurality of line-of-sight grooves of non-circular cross-section between an inlet and an outlet communicating with the upstream and downstream portions, respectively, of the valve or conduit in which it is placed. Contained positioned transverse within each of the grooves are a plurality of longitudinally spaced circular crests formed of screw threads, parallel thin discs or the like. The crests in this arrangement cooperate with the groove walls to define a single stage pressure reducer in a fluid flow path from inlet to outlet through the longitudinal open spacing therebetween.
