Abstract

A filter assembly and method include a body having first second surfaces defining a cavity between the surfaces. A conduit system is disposed within the cavity. The conduit system includes an inlet disposed at the first surface and receives a fluid mixture comprising a fluid and debris. The conduit system is shaped to separate a first portion of the fluid and a mixture of a second portion of the fluid and the debris. The conduit system includes a first outlet disposed at a position within the cavity and a second outlet disposed at the second surface of the body. The conduit system directs the mixture of the second portion of the fluid and the debris out of the conduit system and into the cavity of the body via the first outlet, and directs the first portion of the fluid out of the conduit system via the second outlet.

First claim

What is claimed is:

1. A filter comprising:
a one-piece, continuous, unitary structure defining:
a body comprising a first surface and a second surface, the body defining a cavity between the first and second surfaces; and
a conduit system disposed within the cavity of the body, the conduit system comprising an inlet disposed at the first surface of the body, the conduit system configured to receive a fluid mixture comprising a fluid and debris via the inlet, the conduit system shaped to separate a first portion of the fluid and a mixture of a second portion of the fluid and the debris present in the second portion of the fluid, the conduit system comprising a first outlet disposed at a position within the cavity and a second outlet disposed at the second surface of the body,

wherein the conduit system is configured to direct the mixture of the second portion of the fluid and the debris out of the conduit system and into the cavity of the body via the first outlet, and
wherein the conduit system is configured to direct the first portion of the fluid out of the conduit system and out of the body via the second outlet, wherein the conduit system comprises a first conduit and a second conduit fluidly coupled with the first conduit, the first conduit comprises:
a tubular body defining a central axis;
an elongate body disposed along the central axis of the tubular body;
one or more than one blade extending from the elongate body; and
one or more than one drag feature disposed on or in an internal surface of the tubular body, wherein the elongate body, the one or more than one blade, and the one or more than one drag feature control one or more characteristics of one or more of the fluid mixture, the first portion of the fluid, or the mixture of the second portion of the fluid and the debris within the conduit system.

2. The filter of claim 1 , wherein the first conduit extends between a first end and a second end, and the second conduit extends between a first end and a second end, the second end of the first conduit fluidly coupled with the first end of the second conduit.

3. The filter of claim 2 , wherein the inlet of the conduit system is disposed at the first end of the first conduit, the first outlet of the conduit system is disposed at the second end of the first conduit, and the second outlet of the conduit system is disposed at the second end of the second conduit.

4. The filter of claim 2 , wherein the second end of the first conduit is disposed at a position within the cavity between the first and second surfaces.

5. The filter of claim 2 , wherein the first end of the second conduit is disposed at a position within the cavity between the first and second surfaces.

6. The filter of claim 2 , wherein the first conduit and the second conduit are positioned for establishing a gap between the second end of the first conduit and the first end of the second conduit.

7. The filter of claim 6 , wherein the conduit system is configured for the mixture of the second portion of the fluid and the debris to be directed out of the first conduit through the gap between the second end of the first conduit and the first end of the second conduit.

8. The filter of claim 1 , wherein a portion of at least one internal surface of the conduit system is textured to control one or more characteristics of one or more of the fluid mixture, the first portion of the fluid, or the mixture of the second portion of the fluid and the debris within the conduit system.

9. The filter of claim 1 , wherein the conduit system is a first conduit system, wherein the one-piece, unitary, structure defines plural conduit systems disposed within the cavity defined by the body.

10. The filter of claim 1 , wherein the first and second surfaces of the body are manufactured of a material composition, and the conduit system is manufactured of the same material composition.

11. A filter comprising:
a continuous unitary structure defining:
a body comprising a first surface and a second surface, the body defining a cavity between the first and second surfaces; and
a conduit system disposed within the cavity of the body, the conduit system comprising a first conduit and a second conduit fluidly coupled with the first conduit, the first conduit extending between a first end and a second end, the second conduit extending between a first end and a second end, the conduit system comprising an inlet disposed at the first end of the first conduit, a first outlet disposed at the second end of the first conduit and fluidly coupled with the cavity of the body, and a second outlet disposed at the second end of the second conduit, the conduit system configured to receive a fluid mixture comprising a fluid and debris via the inlet, the conduit system shaped to separate the fluid from the debris within the conduit system,

wherein the conduit system is configured to direct a portion of the debris out of the first conduit and into the cavity of the body via the first outlet, and
wherein the conduit system is configured to direct a portion of the fluid out of the first conduit toward the second conduit, and out of the second conduit via the second outlet, and
wherein the first conduit comprises:
a tubular body;
an elongate body disposed within the tubular body;
one or more than one blade extending from the elongate body; and
one or more than one drag feature disposed on or in an internal surface of the tubular body, wherein the elongate body, the one or more than one blade, and the one or more than one drag feature control one or more characteristics of the fluid mixture within the conduit system.

12. The filter of claim 11 , wherein the first and second surfaces of the body are manufactured of a material composition, and the conduit system are manufactured of the same material composition.

13. The filter of claim 11 , wherein the one or more than one drag feature comprises a plurality of depressions defined into the internal surface of the tubular body.

14. The filter of claim 11 , wherein the one or more than one drag feature comprises a plurality of protrusions extending from the internal surface of the tubular body.

15. The filter of claim 11 , wherein the one or more than one drag feature is separate and distinct from the elongate body and the one or more than one blade.

16. The filter of claim 1 , wherein the one or more than one drag feature comprises a plurality of depressions defined into the internal surface of the tubular body.

17. The filter of claim 1 , wherein the one or more than one drag feature comprises a plurality of protrusions extending from the internal surface of the tubular body.

18. The filter of claim 1 , wherein the one or more than one drag feature is separate and distinct from the elongate body and the one or more than one blade.

19. The filter of claim 1 , where the one or more than one drag feature comprises a plurality of elongated structures extending away from the internal surface of the tubular body.

20. The filter of claim 11 , where the one or more than one drag feature comprises a plurality of elongated structures extending away from the internal surface of the tubular body.
