Abstract

A fluid transport coupling subcomponent can include a body having a first axial end with a first axial face, a second axial end, and a hollow conduit extending between the first and second axial ends, a tongue extending longitudinally from the first axial face; and a groove recessed into the first axial face. The tongue can extend a distance, D T1 , from the first axial face and the groove can extend a distance, D G1 , into the body from the planar face, where D G1 and D T1 can be different.

First claim

What is claimed is:

1. A fluid transport coupling subcomponent comprising:
a body having a first axial end with a first axial face, a second axial end, and a hollow conduit extending between the first and second axial ends,
a tongue extending longitudinally from the first axial face; and
a groove recessed into the first axial face,
wherein the tongue extends a distance, D T1 , from the first axial face,
wherein the groove extends a distance, D G1 , into the body from the first axial face, and
wherein D G1 is different than D T1 , and wherein an outermost radial surface of the tongue and an innermost radial surface of the tongue are both positioned a radial distance from an outermost radial edge of the body and the innermost radial edge of the body at the first axial end, wherein the groove has a generally rectangular profile, wherein the first axial end is tapered relative to the second axial end, and wherein an innermost radial surface of the groove is positioned a radial distance from the innermost radial edge of the body at the first axial end.

2. A fluid transport assembly comprising:
a first component comprising
a body having a first axial end with a first axial face, a second axial end, and a hollow conduit extending between the first and second axial ends,
a tongue extending longitudinally from the first axial face; and
a groove recessed into the first axial face,
wherein the tongue extends a distance, D T1 , from the first axial face,
wherein the groove extends a distance, D G1 , into the body from the first axial face,
wherein D G1 is different than D T1 , and wherein an outermost radial surface of the tongue and an innermost radial surface of the tongue are both positioned a radial distance from an outermost radial edge of the body and the innermost radial edge of the body at the first axial end; and

a second component comprising:
a body having a first axial end, a second axial end with a second axial face, and a hollow conduit extending between the first and second axial ends,
a tongue extending longitudinally from the second axial face; and
a groove recessed into the second axial face,

wherein the tongue extends a distance, D T2 , from the second axial face,
wherein the groove extends a distance, D G2 , into the body from the second axial face,
wherein D G2 is different than D T2 ,
wherein the tongue of the first component is adapted to engage with the groove of the second component, and
wherein the tongue of the second component is adapted to engage with the groove of the first component such that the hollow conduit of the first component is in fluid communication with the hollow conduit of the second component.

3. The fluid transport assembly of claim 2 , the assembly further comprising a nut comprising a hub and a flange, the nut adapted to threadably engage the first and second components together such that the tongue of the first component couples with the groove of the second component and the tongue of the second component couples with the groove of the first component, wherein, in an engaged position, a line extending parallel with a central axis of the fluid transport assembly intersects the flange of the nut, the tongue of the first component, and the groove of the second component.

4. The fluid transport assembly of claim 3 , wherein a ratio of D G1 to D T1 is at least 0.25.

5. The fluid transport assembly of claim 3 , wherein a ratio of D G1 to D T1 is no greater than 5.

6. The fluid transport assembly of claim 3 , wherein a ratio of D G2 to D T2 is at least 0.25.

7. The fluid transport assembly of claim 3 , wherein a ratio of D G2 to D T2 is no greater than 5.

8. The fluid transport assembly of claim 3 , wherein the tongue of the first component and the groove of the second component have complimentary profiles.

9. The fluid transport assembly of claim 3 , wherein the groove of the first component and the tongue of the second component have complimentary profiles.

10. The fluid transport assembly of claim 3 , wherein the body of the first component comprises a flexible polymer tube.

11. The fluid transport assembly of claim 3 , wherein the body of the second component comprises a flexible polymer tube.

12. The fluid transport assembly of claim 3 , wherein the tongue and groove of the first component are monolithic with the first body; and wherein the tongue and groove of the second component are monolithic with the second body.

13. The fluid transport assembly of claim 3 , wherein the body of the first component comprises threading disposed on an outer surface of the body, and wherein the body of the second component comprises threading disposed on an outer surface of the second body.

14. The fluid transport assembly of claim 3 , wherein the body of the first component comprises threading disposed on an outer surface of the body, wherein the body of the second component comprises a flange extending radially from the body, and wherein the fluid transport assembly further comprises a nut comprising internal threading, wherein the internal threading on the nut is adapted to engage with the threading of the first component and the flange of the second component such that as the nut is tightened, the first component and the second component are urged towards each other to form a fluid tight coupling between the first component and the second component.

15. The fluid transport assembly of claim 3 , wherein the nut comprises a flange adapted to contact with a flange of the second component.

16. The fluid transport assembly of claim 3 , wherein the fluid transport assembly maintains a leakproof coupling between the first component and the second component after at least 100,000 cycles of 100 psig inlet pressure with a 3 second on and a 3 second off interval with no back pressure.

17. The fluid transport assembly of claim 3 , wherein the body of the second component is smooth on at least one of the outer or inner surface of the body.

18. A fluid transport assembly comprising:
a first component comprising:
a body having a hollow conduit and an axial end and an axial face;
a tongue extending from the axial face;
a groove recessed into the axial face; and
threading disposed on an outer surface of the body, and wherein an outermost radial surface of the tongue and an innermost radial surface of the tongue are both positioned a radial distance from an outermost radial edge of the body and the innermost radial edge of the body at the first axial end;
