Low noise fluid pressure reducer
First Claim
1. A fluid pressure reducer comprising in combination:
- (a) body means adapted for position placement in a fluid flow conduit;
(b) at least one substantially line-of-sight opening of a predetermined cross sectional geometry extending through said body means between an inlet and outlet for communicating with flow conduit thereat; and
(c) a plurality of crest means contained in a generally transverse orientation longitudinally spaced apart in confining enclosed relation within said opening, said crest means being of a peripheral configuration in transverse section different than the geometrical surface configuration of said opening for cooperating with the opening walls thereat to define at least one longitudinal line-of-sight clearance space intervening therebetween and constituting a passage in which fluid flow can be conducted through said body means.

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.
