Claims


1. A drip irrigation apparatus comprising: a tube formed of a sidewall, said tube having an exterior surface and having an interior conduit defined by an inner surface of said sidewall; a plurality fluid disbursement assemblies positioned sequentially along said inner surface of said tube, each said fluid disbursement assemblies forming a continuous passage for communicating fluid from said interior conduit to said exterior surface, said passage defined by: a first flowpath for fluid running axially along said sidewall; a second flowpath running along said sidewall substantially parallel to said first flowpath; an elongated inlet port communicating with said interior conduit; said inlet port running axially along said first flowpath; an elongated first labyrinth segment running axially along said first flowpath, said first labyrinth segment having a starting end and a terminating end; said inlet port in sealed communication with said starting end of said first labyrinth segment; an discharge chamber running along said second flowpath; said discharge chamber in sealed communication with the termination end of said first labyrinth segment; said inlet sorts running along said first flowpath of each of said sequentially spaced plurality of disbursement assemblies, overlapping the discharge chamber, of any preceding fluid disbursement assembly; and at least one discharge port communicating through said sidewall with said discharge chamber.

2. (canceled)

3. The drip irrigation apparatus of claim 1 additionally comprising: a second elongated inlet port running along said second flowpath; and said second inlet port in sealed communication with said starting end of said first labyrinth segment.

4. (canceled)

5. The drip irrigation apparatus of claim 3 additionally comprising: said sealed communication between said first inlet port and said starting end of said first labyrinth segment comprises a first conduit communicating between said inlet port and said starting end of said first labyrinth segment; and said sealed communication between said second inlet port and said first labyrinth segment comprises a second conduit communicating between said second inlet port and said starting end of said first labyrinth segment.

6. (canceled)

7. The drip irrigation apparatus of claim 5 additionally comprising: said first conduit and said second conduit communicating at said starting end of said first labyrinth segment in opposing directions, whereby fluid communicated from said first conduit and said second conduit communicate in a collision of fluid flows at said starting end.

8. (canceled)

9. The drip irrigation apparatus of claim 7 additionally comprising: said collision providing a means to convert a laminar fluid flow from both said first conduit and said second conduit, to a turbulent fluid flow.

10. (canceled)

11. The drip irrigation apparatus of claim 1 additionally comprising: a third flowpath situated between said first flowpath and said second flowpath; a fourth flowpath situated between said third flowpath and said second flowpath; said first labyrinth segment running along said first flowpath in sealed communication at its termination end with a second labyrinth segment running along said third flowpath which is in sealed communication with a third labyrinth segment running along said fourth flowpath; and said third labyrinth segment in sealed communication at a termination end with said discharge chamber, whereby fluid communicated from said conduit through said inlet port is communicated through successive labyrinths in different flowpaths, to said discharge chamber.

12. (canceled)

13. The drip irrigation apparatus of claim 1 additionally comprising: a third flowpath situated between said first flowpath and said second flowpath; a fourth flowpath situated between said third flowpath and said first flowpath; a second discharge chamber axially positioned along said second flowpath substantially inline with said first discharge chamber; a second labyrinth segment running axially along said third flowpath in a sealed engagement between said first labyrinth segment and said discharge chamber; and a third labyrinth segment running axially along said fourth flowpath in a sealed engagement between said first labyrinth and a second discharge chamber.

14. (canceled)

15. The drip irrigation apparatus of claim 1 additionally comprising: a third flowpath situated between said first flowpath and said second flowpath; a fourth flowpath situated between said third flowpath and said first flowpath; a second labyrinth segment; said first labyrinth segment running along said fourth flowpath in a sealed engagement to said second labyrinth segment running along said third flowpath; and said second labyrinth communicating in a sealed engagement with said first labyrinth segment and discharge chamber.

16. The drip irrigation apparatus of claim 15 additionally comprising: a fifth flowpath situated between said second flowpath and said third flowpath; and a third labyrinth segment running along said fifth flowpath in sealed engagement between said second labyrinth and said discharge chamber.

17. (canceled)

18. (canceled)

19. A method of forming drip irrigation tube providing for closer proximity of fluid disbursing outlets from said tube comprising the steps of: extruding a tube formed of a sidewall, and having an exterior surface and having an interior conduit defined by an inner surface of said sidewall; forming a plurality of fluid disbursement assemblies having a continuous passage for communicating fluid from said interior conduit to said exterior surface, forming each of said fluid disbursement assemblies with: an elongated inlet port communicating with said interior conduit; said inlet port running axially along said tube along a first flowpath; an elongated first labyrinth segment running axially along said tube, substantially inline with said inlet port from a starting end and a terminating end; said inlet port in sealed communication with said starting end of said first labyrinth segment; an outlet chamber running along said tube in a second flowpath substantially parallel to said first flowpath; said outlet chamber in sealed communication with the termination end of said first labyrinth segment; and at least one discharge port; placing said plurality fluid disbursement assemblies sequentially along said inner surface of said tube as said tube is being extruded; and forming at least one discharge port through said sidewall an into each of said outlet chamber positioned on said inner surface.

20. The method of forming drip irrigation tube providing for closer proximity of fluid disbursing outlets from said tube of claim 19 with the additional step of: overlapping the position of said inlet ports of said sequentially spaced plurality of disbursement assemblies, with the position of the outlet chamber, of any preceding fluid disbursement assembly during placement of said fluid disbursing outlets on said interior surface.

21. A method of forming the drip irrigation apparatus as defined in claim 1 comprising the steps of: extruding a tube formed of a sidewall, and having an exterior surface and having an interior conduit defined by an inner surface of said sidewall; placing a plurality of said fluid disbursement assemblies sequentially along said inner surface of said tube as said tube is being extruded; overlapping the position of said inlet ports of said sequentially spaced plurality of disbursement assemblies, with a respective said discharge chamber of any preceding fluid disbursement assembly during said placing of said fluid disbursing outlets on said interior surface; and forming at least one discharge port through said sidewall in a position on said sidewall to communicate with a respective of said discharge chambers positioned on said inner surface.
