Abstract

An essentially non-electric automatic fluid dispensing system is provided wherein a first induced pressure induces flow of a first fluid, which in the preferred embodiment is a liquid sanitizer. The system further divides the first fluid into a first divided fluid and second divided fluid, said first divided fluid inducing flow into a second fluid located in an airtight container for the second fluid, a regulator valve for varying the second divided fluid, a dispensing valve for displacing the second fluid from the said container under pressure and for varying the flow rate of the said displaced second fluid, and connector for impressing the displaced fluid into a receiving line which in the preferred embodiment is a water circulation circuit.

5. An automatic fluid dispensing system in accordance with claim 1 wherein:

the fluid disposed within the container is of greater specific gravity than the first divided flow portion, and whereby displacement of fluid disposed within said container is induced by pressure induced upon the first divided portion and impressed upon fluid disposed within the container.

6. An automatic fluid dispensing system in accordance with claim 1 wherein:

the means for displacing fluid disposed within the container comprises strainer means, tubing means connected to the strainer means and weight means coupled to the strainer means, all immersed within said disposed fluid, passageway connector means attached to said tubing means, and output connector means connected to the passageway connector means for displaced fluid, and

wherein the strainer means forms an anti-clogging means.

7. An automatic fluid dispensing system in accordance with claim 1 wherein:

means that varies said fluid flow at the second fluid dividing means comprises a valve with a variable passageway interposed in the transmitting means that transmits the second fluid flow divided portion to second fluid dividing means.

8. An automatic fluid dispensing system in accordance with claim 1 wherein:

the means of transmitting said displaced fluid from said output to the second fluid flow dividing means permits fluid flow in only one direction.

9. An automatic fluid dispensing system in accordance with claim 8 wherein:

the transmitting means comprises a check valve, and the fluid flow in one direction comprises displaced fluid.

10. An automatic fluid dispensing system in accordance with claim 9 wherein:

said induced pressure in the water circulation line is impressed upon the second fluid flow dividing means and the displaced fluid flow is the result of a combination of said induced pressure in a water circulation circuit, and pressure induced upon the displaced fluid, and pressure induced upon the second divided fluid portion and valve means for varying said pressure.

11. An automatic fluid dispensing system in accordance with claim 1 wherein:

the means for transmitting said displaced fluid from the second fluid flow dividing means to the displaced fluid receiving means comprises tubing, and wherein said fluid is the result of induced pressure impressed upon displaced fluid, and pressure induced upon second divided fluid portion and valve means for varying said pressure.

12. An automatic fluid dispensing system in accordance with claim 1 wherein:

the means for transmitting said displaced fluid from the second fluid flow dividing means to the displaced fluid receiving means is tubing, and wherein the receiving means comprises a circulation, having induced pressure.

13. An automatic fluid dispensing system in accordance with claim 1 wherein:

the fluid flow input means comprises tubing, and wherein the diverter valve means connected to said tubing forms selective means of impressing input fluid, to either first fluid flow dividing means, or the displaced fluid output connector thereby forming selectable means for reverse flow of pressure thereby induced, and thereby forming selectable separate passageway anti-clogging means.

14. An automatic fluid dispensing system in accordance with claim 1 further including:

valve means wherein induced pressure on the input fluid is impressed upon valve means that activates when predetermined pressure is exceeded, thereby releasing unwanted pressure, and thereby forming over-pressure safety means.

15. An automatic fluid dispensing system in accordance with claim 1 further including:

gauge means wherein induced pressure on the input fluid is impressed on the gauge means which forms input fluid pressure readout means.

16. An automatic fluid dispensing system in accordance with claim 1 wherein:

the displaced fluid output means comprises separate passageways, and includes orifice means that is removable and is therein disposed, and gasket means to form an airtight seal which forces the flow of displaced fluid through said orifice, and thereby forming a means of varying an extremely small displaced fluid flow rate.

17. An automatic fluid dispensing system in accordance with claim 1 further including:

a plurality of first fluid flow dividing means which divides the inputted fluid flow into a plurality of first fluid flow divided portions and a plurality of second fluid flow divided portions;

a plurality of airtight containers;

means for impressing said first fluid divided portions and said induced pressure upon fluid disposed within a plurality of said containers;
