Patent ID: 7910074

Claim:
A liquid transfer system operable to transfer liquid from at least one container to at least one destination, the liquid transfer system comprising: a) at least one container; b) at least one liquid input line including at least one valve, wherein the liquid input line leads to the at least one container; c) at least one vacuum source; d) at least one destination; e) a first chamber adapted to retain liquid, the first chamber including i) a first liquid inlet port connected to the at least one liquid input line, ii) a pressure port connected to the at least one vacuum source, and configured to subject the first chamber to a vacuum, and iii) a first liquid outlet port; f) a second chamber adapted to retain liquid, the second chamber including i) a second liquid inlet port, ii) a second liquid outlet port connected to the at least one destination, and iii) a vent; and g) at least one liquid output line wherein the at least one liquid output line leads from the first liquid outlet port to the second liquid inlet port; wherein the at least one valve of the at least one liquid input line is configured to move between an open position and a closed position to control the flow of liquid to the first chamber, wherein the at least one liquid output line is configured to move between an open position and a closed position to control the flow of liquid to the second chamber, and wherein the at least one vacuum source is configured to apply a vacuum when the at least one valve of the at least one liquid input line and the at least one liquid output line are in the closed position so as to define a closed system to degas liquid in the first chamber.
