Abstract

A fluid conduit has a longitudinal flow passage which includes a transverse cross section that is configured as a polygon, such as a convex or a concave polygon.

First claim

What is claimed is:

1. A fluid conduit which comprises an outer surface having a transverse cross section configured as a circle and a single longitudinal flow passage having a non-expandable transverse cross section configured as a polygon.

2. The fluid conduit of claim 1 , wherein the fluid conduit comprises a pipe bend and the flow passage extends through the bend.

3. The fluid conduit of claim 1 , wherein the fluid conduit comprises a body of a flow control valve.

4. The fluid conduit of claim 3 , wherein the flow passage extends generally linearly through the body.

5. The fluid conduit of claim 3 , wherein the flow passage extends non-linearly through the body.

6. The fluid conduit of claim 2 or 3 , wherein the transverse cross section is configured as a convex polygon.

7. The fluid conduit of claim 6 , wherein the transverse cross section is configured as a triangle.

8. The fluid conduit of claim 7 , wherein the triangle comprises one of an isosceles triangle, an equilateral triangle, a right triangle or a scalene triangle.

9. The fluid conduit of claim 7 , wherein the triangle comprises a side nearest a center of curvature of the bend and said side is generally perpendicular to a direction of a radius of the bend.

10. The fluid conduit of claim 6 , wherein the transverse cross section is configured as a convex polygon having four sides.

11. The fluid conduit of claim 10 , wherein the transverse cross section is configured as one of a square, a parallelogram, a rhombus or a kite.

12. The fluid conduit of claim 6 , wherein the transverse cross section is configured as one of a pentagon, a hexagon, or an octagon.

13. The fluid conduit of claim 2 or 3 , wherein the transverse cross section is configured as a concave polygon.

14. The fluid conduit of claim 13 , wherein the concave polygon has ten sides.

15. The fluid conduit of claim 13 , wherein the concave polygon comprises an asymmetric configuration.

16. A fluid conduit which comprises a plurality of individual first fluid conduits which are bundled together laterally, each first fluid conduit comprising a longitudinal flow passage having a transverse cross section that is configured as a polygon.

17. The fluid conduit of claim 16 , wherein each first fluid conduit comprises a tubular member.

18. The fluid conduit of claim 17 , wherein each first fluid conduit comprises a triangular cross section having a base and an apex.

19. The fluid conduit of claim 18 , wherein the first fluid conduits are bundled together such that the bases form an outer periphery of the fluid conduit and the apexes form a radially inner aperture.

20. The fluid conduit of claim 19 , further comprising a second fluid conduit which is positioned within the aperture.

21. The fluid conduit of claim 20 , wherein the second fluid conduit comprises a longitudinal flow passage having a transverse cross section that is configured as a convex polygon.

22. The fluid conduit of claim 20 , wherein the second fluid conduit comprises a longitudinal flow passage having a transverse cross section that is configured as a concave polygon.

23. A fluid conduit which comprises a plurality of longitudinal flow passage, each of which comprises a transverse cross section that is configured as a polygon, wherein the fluid conduit comprises a body of a flow control valve.

24. The fluid conduit of claim 23 , wherein the transverse cross section is configured as a convex polygon.

25. The fluid conduit of claim 24 , wherein the transverse cross section is configured as a triangle.

26. The fluid conduit of claim 23 , wherein the transverse cross section is configured as a concave polygon.

27. The fluid conduit of claim 26 , wherein the concave polygon has ten sides.

28. The fluid conduit of claim 26 , wherein the concave polygon comprises an asymmetric configuration.

29. The fluid conduit of claim 1 , wherein the flow passage includes a first end portion having a transverse cross section which is configured as a circle, a second end portion having a transverse cross section which is configured as a circle, and a main portion which extends between the first and second end portions and comprises a transverse cross section that is configured as a convex polygon.

30. The fluid conduit of claim 29 , wherein the flow passage comprises a first transition section connecting the first end portion with the main portion and a second transition section connecting the second end portion with the main section, whereby the first and second transition sections provide a smooth transition between the cross section of the main portion and the respective cross sections of the first and second end portions.

31. The fluid conduit of claim 30 , wherein the first and second transition sections are configured generally as cones having circular cross sections which increase in diameter from the main portion toward the first and second end portions.
