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.
Claims28
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.

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.

A method for manufacturing a fluid noise suppressor comprising:
- providing a resilient insert having an outer surface and an inner surface, the inner surface defining therethrough a channel for a fluid flowing along a length of the resilient insert, the resilient insert is operable to dampen a fluctuation of a total pressure in the fluid that exceeds a mean static pressure, providing effective fluid-borne noise suppression that without the resilient insert, would have occurred in the flowing fluid with the fluctuation;
- providing an outer shell extending along the outer surface of the resilient insert, the outer shell having an integral fluid connector, and an inner wall, the integral fluid connector disposed on a upstream end of the outer shell is configured to provide fluid connectivity between a upstream portion of the channel and an upstream end of a fluidic conduit;
- providing a restraining insert comprising a permeable tube operable to enable fluidic communication between the outer surface of the resilient insert and the channel;
- providing a discrete fluid connector disposed on a downstream end of the outer shell is configured to provide fluid connectivity between a downstream portion of the channel and a downstream end of the fluidic conduit;
- inserting the restraining insert within the outer shell;
- inserting the resilient insert into the outer shell;
- and
- attaching the discrete fluid connector to the downstream end of the outer shell.
