NOISE REDUCING FLUID PASSAGEWAYS FOR FLUID FLOW CONTROL DEVICES
First Claim
1. A device for controlling fluid flow comprising:
- a fluid inlet;
a fluid outlet;
a trim disk assembly configured to provide a pressure differential between fluid disposed at the fluid inlet and fluid disposed at the fluid outlet, the trim disk assembly comprising;
a substantially planar first disk comprising a first major surface and a second major surface, the first disk including an elongated void formed at least partially through the first disk in one of the first major surface and the second major surface thereof;
a substantially planar second disk disposed adjacent the substantially planar first disk, the second disk comprising a first major surface and a second major surface, the second disk including an elongated void formed at least partially through the second disk in one of the first major surface and the second major surface thereof, the void of the second disk having a shape and size substantially similar to a shape and size of the void of the first disk, the second disk being aligned with the first disk to provide fluid communication between the void of the first disk and the void of the second disk, the void of the first disk being offset from the void of the second disk;
wherein the void of the first disk and the void of the second disk together at least partially define a fluid passageway; and
at least two substantially planar spacer disks, the first disk and the second disk being disposed between the at least two spacer disks, the void in the first disk extending through the first disk from the first major surface to the second major surface of the first disk, the void in the second disk extending through the second disk from the first major surface to the second major surface of the second disk, wherein at least a portion of a surface of a first spacer disk and at least a portion of a surface of a second spacer disk at least partially define the fluid passageway.

Abstract
Trim disk assemblies for use in fluid flow control devices include a first disk and a second disk. An elongated void is formed in a surface of each of the first disk and the second disk. The second disk is aligned with the first disk to provide fluid communication between the void of the first disk and the void of the second disk, the void of the first disk being offset or staggered from the void of the second disk. The void of the first disk and the void of the second disk at least partially define a fluid passageway having a cross-sectional area characterized by increases and decreases in cross-sectional area, which define an expansion/contraction mechanism of the fluid passageway.
