Abstract

An apparatus for distributing fluid comprises a circular, cylindrical valve body and a circular, cylindrical core. The body is centered with respect to a cylinder axis and has a perimeter. Three outlets, each of which communicates with one of three conduits, are positioned at 120 degrees relative to each other on the perimeter of the body. The core comprises a channel and a rotational axis which is collinear with respect to the cylinder axis of the body. The core has a periphery and fits into the body wherein the perimeter and periphery are in communication with each other. The core is rotatable within the body, and the channel connects two of the three outlets of the body to each other according to the position of the core with respect to the body.

Claims

1. An apparatus for distributing fluid, comprising:

a circular, cylindrical valve body comprising a cylinder axis and a perimeter, said body being centered with respect to said cylinder axis;

said body further comprising three outlets being positioned at 120 degrees relative to each other on said perimeter, each of said three outlets communicating with one of three conduits;

a circular, cylindrical core comprising a rotational axis and a channel, said rotational axis being collinear with respect to said cylinder axis;

said core further comprising a periphery, said core fitting into said body, said perimeter and said periphery being in communication with each other, said core being rotatable within said body; and

said channel connecting two of said three outlets of said body to each other according to a position of said core with respect to said body.

2. The apparatus of claim 1, wherein said channel of said core is one of secant and straight.

3. The apparatus of claim 1, wherein said channel of said core is straight, said channel being offset with respect to said rotational axis.

4. The apparatus of claim 1, wherein said core is hollow.

5. The apparatus of claim 1, further comprising a wheel being attached to said core to rotate said core within said body.

6. The apparatus of claim 1, wherein said channel has a diameter within a range of about 1 mm to about 2 mm.

7. The apparatus of claim 1, wherein said core has a diameter of about 8 mm.

8. The apparatus of claim 1, wherein said core and said body comprise plastic.

9. The apparatus of claim 1, wherein said core and said body are formed by injection molding.

10. The apparatus of claim 1, further comprising:

a clip in communication with said periphery of said core; and

said perimeter of said body further comprising a recess receiving said clip to retain said core within said body.

11. The apparatus of claim 1, said body further comprising a hollow needle extending into one of said three conduits, said hollow needle conveying fluid into said one of said three conduits.

12. The apparatus of claim 1, further comprising:

a receptacle for receiving a bottle having a plug; and

said body further comprising a hollow needle extending into one of said three conduits, said receptacle being positioned with respect to said hollow needle to facilitate perforating said plug with said hollow needle.

13. The apparatus of claim 1, further comprising a receptacle for receiving a syringe piston, said receptacle opening into one of said three conduits to convey fluid into said one of said three conduits.

14. The apparatus of claim 1, said body further comprising one of a syringe piston receptacle, a grooved connecting piece, and a syringe tip receptacle interconnecting with one of said three conduits to convey fluid into said one of said three conduits.

15. A method for distribution of fluid, said method comprising:

providing a circular, cylindrical core in a circular, cylindrical valve body to form a three-way valve, said body comprising a perimeter and first, second, and third outlets being positioned equidistant relative to each other on said perimeter, each of said first, second, and third outlets communicating with one of three conduits, said core comprising a channel having first and second holes at either end for conveying fluid between two of said first, second, and third outlets; and

configuring said three-way valve wherein in a first position of said core, said channel interconnecting two of said first, second, and third outlets.

16. The method of claim 15, further comprising rotating said core to a second position being 120 degrees with respect to said first position, wherein said channel interconnecting two outlets of said first, second, and third outlets, said two outlets being different with respect to said first position.

17. The method of claim 16, further comprising rotating said core to a third position being 240 degrees with respect to said first position, wherein said channel interconnecting two outlets of said first, second, and third outlets, said two outlets being different with respect to said first and second positions.

18. An apparatus for the distribution of fluid, comprising:

an array of three-way valves, each of said three-way valves comprising;

a circular, cylindrical valve body comprising a cylinder axis and a perimeter, said body being centered with respect to said cylinder axis, said body further comprising three outlets and three conduits, said three outlets being positioned at 120 degrees relative to each other on said perimeter and communicating with one of said three conduits;

a circular, cylindrical core comprising a rotational axis and a channel, said rotational axis being collinear with respect to said cylinder axis, said core further comprising a periphery, said core fitting into said body wherein said perimeter and said periphery being in communication with each other, said channel connecting two of said three outlets of said body to each other according to a position of said core with respect to said body; and

a common general conduit interconnecting said array, said common general conduit being in communication with at least one of said three outlets of each of said three-way valves.

19. The apparatus of claim 18, said array further comprising approximately 25 three-way valves.

20. The apparatus of claim 18, wherein said common general conduit being in communication with two of said three outlets of at least one of said three-way valves.
