Abstract

An example fluid system can include a fluid noise suppressor having a resilient insert having an outer surface; wherein the resilient insert can be operable to dampen a fluctuation of a total pressure about a mean static pressure, providing effective noise reduction that without the resilient insert, would have occurred in the flowing fluid with the fluctuation; and wherein the mean static pressure can be between about 100 psig to about 10,000 psig.

First claim

What is claimed is:

1. A fluid system comprising:
a fluid noise suppressor comprising:
a resilient insert having an outer surface;
an outer shell extending for a length of the outer surface of the resilient insert; and
a permeable cage extending along the outer surface of the resilient insert and positioned between the outer shell and the resilient insert;
wherein the resilient insert is operable to dampen a fluctuation of a total pressure about a mean static pressure, providing effective noise reduction that without the resilient insert, would have occurred in a flowing fluid with the fluctuation; and
wherein the mean static pressure is between about 100 psig to about 10,000 psig.

2. The fluid system of claim 1 , wherein the outer shell defines a fluid channel between the outer surface of the resilient insert and an inner surface of the outer shell.

3. The fluid system of claim 1 , wherein the fluid noise suppressor further comprises a restraining portion integral to the outer shell and operable to restrain the resilient insert within the outer shell.

4. The fluid system of claim 1 , wherein the resilient insert and the outer shell are concentrically aligned.

5. The fluid system of claim 1 , wherein the resilient insert further comprises an inner surface defining therethrough a channel for a fluid flowing along a length of the resilient insert having a mean static pressure.

6. The fluid system of claim 1 further comprising an existing length of a fluidic conduit;
wherein the fluid noise suppressor is located between an upstream portion and downstream portion of the existing length of the fluidic conduit; and
wherein the upstream portion of the existing length of the fluidic conduit, the fluid noise suppressor, and the downstream portion of the existing length of the fluidic conduit, are in fluidic communication along the existing length of the portions and fluid noise suppressor.

7. The fluid noise suppressor system of claim 6 further comprising:
a fluid inlet connector disposed on an upstream end of the fluid noise suppressor providing both connectivity of the upstream end of the fluid noise suppressor to the upstream portion of the fluidic conduit and to inhibit travel of the resilient insert into the upstream portion of the fluidic conduit; and
a fluid outlet connector disposed on a downstream end of the fluid noise suppressor providing both connectivity of the downstream end of the fluid noise suppressor to the downstream portion of the fluidic conduit and to inhibit travel of the resilient insert into the downstream portion of the fluidic conduit.

8. The fluid system of claim 1 , wherein the resilient insert comprises a first discrete resilient insert portion and a second discrete resilient insert portion that are operable to physically abut one another, preventing radial compression of the resilient insert that would lead to ineffective noise reduction.

9. The fluid system of claim 1 , wherein the resilient insert has an annular cross-section.

10. The fluid system of claim 8 , wherein the resilient insert is segmented axially to form the first discrete resilient insert portion and the second discrete resilient insert portion.

11. The fluid system of claim 8 , wherein each discrete resilient insert portion comprises:
a polymeric matrix having a stiffness; and
microspheres dispersed within the polymeric matrix;
wherein the microspheres are pressurized to a pressure of 0.1 MPa or greater; and
wherein the stiffness of the polymeric matrix of at least one of the discrete resilient insert portions is different from another of the discrete resilient insert portions.

12. The fluid system of claim 1 , wherein resilient insert comprises:
a polymeric matrix having a stiffness; and
microspheres dispersed within the polymeric matrix.

13. The fluid system of claim 12 , wherein the microspheres are pressurized to an internal pressure of 0.1 MPa or greater; and
wherein the microspheres are homogeneously dispersed within the polymeric matrix.

14. The fluid system of claim 12 , wherein the microspheres are pressurized to an internal pressure of 0.1 MPa or greater; and
wherein the microspheres are heterogeneously dispersed within the polymeric matrix.

15. A fluid noise suppressor system comprising:
an upstream portion of a fluidic conduit;
a fluid noise suppressor located downstream of the upstream portion of the fluidic conduit; and
a downstream portion of the fluidic conduit being located downstream of the fluid noise suppressor;
wherein the fluid noise suppressor comprises:
a resilient insert having an outer surface, an annular cross-section and comprising at least two discrete resilient insert portions;
wherein the fluid noise suppressor and the portions of the fluidic conduit are configured for a flowing fluid within each having a mean static pressure;
wherein the at least two discrete resilient insert portions are operable to physically abut one another, preventing radial compression of the resilient insert that would lead to ineffective fluid noise reduction;
wherein the resilient insert is operable to dampen a fluctuation of a total pressure about a mean static pressure, providing effective noise reduction that without the resilient insert, would have occurred in the flowing fluid with the fluctuation;
wherein the mean static pressure is between about 100 psig to about 10,000 psig; and
wherein each discrete resilient insert portion comprises a partially annular cross-section.

16. The fluid noise suppressor system of claim 15 , wherein the fluid noise suppressor further comprises an outer shell extending for a length of the outer surface of the resilient insert; and
wherein the resilient insert further has an inner surface defining therethrough a channel having an inner diameter substantially similar to an inner diameter of the upstream and downstream portions of the fluidic conduit.

17. The fluid system of claim 15 , wherein the resilient insert is segmented axially to form the discrete resilient insert portions.

18. The fluid noise suppressor system of claim 15 further comprising:
a fluid inlet connector disposed on an upstream end of the fluid noise suppressor providing both connectivity of the upstream end of the fluid noise suppressor to the upstream portion of the fluidic conduit and to inhibit travel of the resilient insert into the upstream portion of the fluidic conduit; and
a fluid outlet connector disposed on a downstream end of the fluid noise suppressor providing both connectivity of the downstream end of the fluid noise suppressor to the downstream portion of the fluidic conduit and to inhibit travel of the resilient insert into the downstream portion of the fluidic conduit.

19. The fluid noise suppressor system of claim 18 further comprising a permeable tube extending for a length of an inner surface of the resilient insert and operable to enable fluidic communication from the fluid inlet connector through the fluid outlet connector;
wherein the inner surface of the resilient insert defines therethrough a channel having an inner diameter substantially similar to an inner diameter of the upstream and downstream portions of the fluidic conduit.

20. The fluid noise suppressor system of claim 19 , wherein the fluid noise suppressor further comprises an outer shell extending for a length of the outer surface of the resilient insert; and
wherein the permeable tube further comprises a flange located on least at one end of the permeable tube and operable to rest
