Abstract

An apparatus for a liquid and pressurized gas includes a gas inlet hose for conducting the pressurized gas therethrough, a liquid inlet hose, extending through the interior of the gas inlet hose, for conducting the liquid therethrough, a hose separator connected to an end of the gas and liquid inlet hoses, a gas outlet hose connected through the hose separator so as to be in fluid communication with the gas inlet hose for further conducting the pressurized gas therethrough, a liquid outlet hose, separate from the gas outlet hose, connected through the hose separator so as to be in fluid communication with the liquid inlet hose for further conducting the liquid therethrough, and a main outlet hose connected to and in fluid communication with the liquid outlet hose and the gas outlet hose. The apparatus further includes a first valve positioned within the liquid outlet hose to regulate flow therethrough and a second valve positioned within the gas outlet hose to regulate flow therethrough.

Claims

1. An apparatus for dispensing liquids and pressurized gas, comprising:

gas inlet hose means having an interior for conducting a pressurized gas therethrough;

liquid inlet hose means for conducting a primary liquid therethrough in the same direction as the pressurized gas is conducted, said liquid inlet hose means extending through said interior along the entire length of said gas inlet hose means;

a hose separator connected to a first end of said gas inlet hose means and a first end of said liquid inlet hose means;

a gas outlet hose means having a first end and a second end, said first end of said gas outlet hose means connected through said hose separator so as to be in fluid communication with said gas inlet hose means for further conducting the pressurized gas therethrough;

a liquid outlet hose means external to said gas outlet hose means, said liquid outlet hose means having a first end and a second end, said first end of said liquid outlet hose means connected through said hose separator so as to be in fluid communication with said liquid inlet hose means for further conducting the primary liquid therethrough; and

a main outlet hose means connected to and in fluid communication with said second end of said liquid outlet hose means and said second end of said gas outlet hose means for conducting at least one of the pressurized gas and the primary liquid therethrough.

2. An apparatus as claimed in claim 1, further comprising a first valve means positioned within said liquid outlet hose means for regulating flow therethrough and a second valve means positioned within said gas outlet hose means for regulating flow therethrough.

3. An apparatus as claimed in claim 2, wherein said main outlet hose means includes an upstream end and a downstream end, said second end of said liquid outlet hose means being connected to said upstream end of said main outlet hose means and said second end of said gas outlet hose means being connected to said downstream end of said main outlet hose means.

4. An apparatus as claimed in claim 1 further comprising a tank for containing a supply of the primary liquid in a lower portion thereof and a supply of the pressurized gas in an upper portion thereof, wherein a second end of said gas inlet hose means is connected to said upper portion of said tank for conducting the pressurized gas therefrom and a second end of said liquid inlet hose means extends into said lower portion of said tank for conducting the primary liquid therefrom.

5. An apparatus as claimed in claim 4, further comprising a first valve means positioned within said liquid outlet hose means for regulating flow therethrough, and a second valve means positioned within said gas outlet hose means for regulating flow therethrough.

6. An apparatus as claimed in claim 5, wherein said main outlet hose means includes an upstream end and a downstream end, said second end of said liquid outlet hose means being connected to said upstream end of said main outlet hose means and said second end of said gas outlet hose means being connected to said downstream end of said main outlet hose means.

7. An apparatus as claimed in claim 1, further comprising a secondary liquid inlet hose means for conducting a secondary liquid therethrough, said secondary liquid inlet hose means extending through said interior of said gas inlet hose means wherein a first end of said secondary liquid inlet hose means is connected to said hose separator;

and

a secondary liquid outlet hose means having a first end and a second end, said secondary liquid outlet hose means being external to said gas outlet hose means, said first end of said secondary liquid outlet hose means connected to said hose separator so as to be in fluid communication with said secondary liquid inlet hose means for further conducting the secondary liquid therethrough, and wherein said second end of said secondary liquid outlet hose means is connected to said main outlet hose means.

8. An apparatus as claimed in claim 7, further comprising a first valve means positioned within said liquid outlet hose means for regulating flow therethrough, a second valve means positioned within said gas outlet hose means for regulating flow therethrough, and a third valve means positioned within said secondary liquid outlet hose means for regulating flow therethrough.

9. An apparatus as claimed in claim 8, wherein said main outlet hose means includes an upstream end and a downstream end, said second end of said liquid outlet hose means and said second end of said secondary liquid outlet hose means being connected to said upstream end of said main outlet hose means, and said second end of said gas outlet hose means being connected to said downstream end of said main outlet hose means.

10. An apparatus as claimed in claim 7 further comprising a primary tank for containing a supply of the primary liquid in a lower portion thereof and a supply of the pressurized gas in an upper portion thereof and a secondary tank for containing a supply of a secondary liquid in a lower portion thereof and a supply of the pressurized gas in an upper portion thereof, wherein a second end of said gas inlet hose means is connected to said upper portion of said priming tank for conducting the pressurized gas therefrom, a second end of said liquid inlet hose means extends into said lower portion of said primary tank for conducting the primary liquid therefrom, and a second end of said secondary liquid inlet hose means extends into said lower portion of said secondary tank for conducting the secondary liquid therefrom.

11. An apparatus as claimed in claim 10, further comprising a first valve means positioned within said liquid outlet hose means for regulating flow therethrough, a second valve means positioned within said gas outlet hose means for regulating flow therethrough, and a third valve means positioned within said secondary liquid outlet hose means for regulating flow therethrough.

12. An apparatus as claimed in claim 11, wherein said main outlet hose means includes an upstream end and a downstream end, said second end of said liquid outlet hose means and said second end of said secondary liquid outlet hose means being connected to said upstream end of said main outlet hose means, and said second end of said gas outlet hose means being connected to said downstream end of said main outlet hose means.
