Abstract

In order to discipate energy from a high pressure fluid without causing damage and environmental nuisanse an energy loss device is used. This device includes energy loss paths including void areas arranged to draw energy from the high pressure fluid as it passes through the path. These paths may also include turns and other features to enhance energy loss.

Claims

1. A fluid flow controlling device comprising:

a plurality of members joined together into a rigid structure to define a series of radial respectively isolated energy loss paths for fluid flow, said plurality of members including a series of disks having abutting surfaces and forming said energy loss paths in a respective common plane there between for fluid flow there along wherein at least one of the energy loss paths of the disk includes a void between the inlet and outlet of the disk, the void expanding the cross-sectional area of the said energy loss path of the disk;

inlet means centrally formed in said members along a first configuration to define a predetermined inlet area for conducting fluid to the series of paths formed by said plurality of members; and

,

outlet means associated with said inlet means and about said rigid structure to provide a series of openings for exhausting fluid from the energy loss paths of said rigid structure.

2. A fluid flow controlling device as claimed in claim 1 wherein the void has a cross-sectional shape that is one of rectilinear, rounded, diamond shaped, T shaped and arrowhead shaped.

3. A fluid flow controlling device as claimed in claim 1 wherein the energy loss paths include turns or deviations in their configuration to further enhance energy loss.

4. A fluid flow controlling device as claimed in claim 1 wherein the device is arranged to exhaust high pressure steam.

5. A fluid flow controlling device as claimed in claim 1 wherein the inlet passage has a width of 0.20" (5.0 mm) and the outlet passage a width of 0.25" (6.25 mm) with a passage depth of 0.19" (4.75 mm) whilst the void has a width of 0.4" (10 mm) and a similar depth as the inlet and outlet passages.

6. A fluid flow controlling device as claimed in claim 1, wherein each energy loss path comprises a groove defined in a said disk, said energy loss paths having a vertical dimension less than or equal to a vertical dimension of a said disk.
