Abstract

A three way coupler includes a housing having a bore to receive fluid, and having two ends for coupling to pipes, and having an orifice communicating with the bore of the housing. A barrel is secured to the housing and includes a hole communicating with the bore of the housing. An adjusting device includes a shank rotatably engaged into the orifice of the housing, and having a passage to selectively align with the bore of the housing, and to adjust a flowing of the fluid through the bore of the housing. Another adjusting device may be attached to the barrel, to adjust a flowing of the fluid through the hole of the barrel.

Claims

1. A three way coupler comprising:

a housing including a bore formed therein for receiving fluid therethrough, and including two ends for pipe coupling purposes, and including an orifice formed therein and communicating with said bore of said housing,

a barrel secured to said housing, and including a hole formed therein, and communicating with said bore of said housing, and

a first adjusting device including a shank rotatably engaged into said orifice of said housing, and including a passage formed in said shank, for selectively aligning with said bore of said housing, and to adjust a flowing of the fluid through said bore of said housing.

2. The three way coupler as claimed in claim 1 further comprising a second adjusting device attached to said barrel, to adjust a flowing of the fluid through said hole of said barrel.

3. The three way coupler as claimed in claim 2., wherein said second adjusting device includes a stem rotatably engaged into said hole of said barrel and includes a pathway formed in said stem and communicating with said bore of said housing.

4. The three way coupler as claimed in claim 3, wherein said barrel includes a manifold extended therefrom and having a passage formed therein and communicating with said hole of said barrel, said stem includes a port formed therein and communicating with said pathway of said stem to selectively align with said passage of said manifold when said stem is rotated relative to said barrel, and to adjust the flowing of the fluid through said passage of said manifold.

5. The three way coupler as claimed in claim 3 further comprising means for positioning said stem to said barrel.

6. The three way coupler as claimed in claim 5, wherein said stem includes a knob having a plurality of depressions formed therein, said positioning means includes a spring biased projection received in said barrel, and selectively engageable into either of said depressions of said knob, to position said stem to said barrel at selected angular position.

7. The three way coupler as claimed in claim 3 further comprising two sealing rings engaged between said stem and said barrel, to make a fluid-tight seal between said stem and said barrel.

8. The three way coupler as claimed in claim 3 further comprising a retaining ring attached to said stem, and engaged with said barrel, to rotatably secure said stem of said second adjusting device to said barrel.

9. The three way coupler as claimed in claim 1 further comprising means for positioning said shank of said first adjusting device to said housing.

10. The three way coupler as claimed in claim 9, wherein said shank includes a knob having a plurality of depressions formed therein, said positioning means includes a spring biased projection received in said housing, and selectively engageable into either of said depressions of said knob, to position said shank of said first adjusting device to said housing at selected angular position.

11. The three way coupler as claimed in claim 1 further comprising two sealing rings engaged between said shank and said housing, to make a fluid-tight seal between said shank and said housing.

12. The three way coupler as claimed in claim 1 further comprising a retaining ring attached to said shank, and engaged with said housing, to rotatably secure said shank of said first adjusting device to said housing.

13. A three way coupler comprising:

a housing including a bore formed therein for receiving fluid therethrough, and including two ends for pipe coupling purposes, and including an aperture formed therein and communicating with said bore of said housing,

a barrel including a first end engaged into said aperture of said housing, and secured to said housing, and including a hole formed therein, and communicating with said bore of said housing, and including a passage formed therein and communicating with said hole of said barrel, and

a first adjusting device including a stem rotatably engaged into said hole of said barrel, and including a pathway formed in said stem, and communicating with said bore of said housing, and including a port formed in said stem, and communicating with said pathway of said stem, for selectively aligning with said passage of said barrel, and to adjust a flowing of the fluid through said passage of said barrel.

14. The three way coupler as claimed in claim 13 further comprising means for positioning said stem of said first adjusting device to said barrel.

15. The three way coupler as claimed in claim 14, wherein said stem includes a knob having a plurality of depressions formed therein, said positioning means includes a spring biased projection received in said barrel, and selectively engageable into either of said depressions of said knob, to position said stem of said first adjusting device to said barrel at selected angular position.

16. The three way coupler as claimed in claim 13 further comprising a second adjusting device attached to said housing, to adjust a flowing of the fluid through said bore of said housing,

17. The three way coupler as claimed in claim 16, wherein said housing includes an orifice formed therein and communicating with said bore of said housing, said second adjusting device includes a shank rotatably engaged into said orifice of said housing and includes a passage formed in said shank for selectively aligning with said bore of said housing, to adjust the flowing of the fluid through said bore of said housing.

18. The three way coupler as claimed in claim 17 further comprising means for positioning said shank to said housing.

19. The three way coupler as claimed in claim 18, wherein said shank includes a knob having a plurality of depressions formed therein, said positioning means includes a spring biased projection received in said housing, and selectively engageable into either of said depressions of said knob, to position said shank to said housing at selected angular position.
