Portable fluid exchange system for concurrently pumping liquid from a source container to a destination container and pumping vapor from the destination container to the source container
First Claim
1. A portable fluid exchange system for concurrently pumping liquid from a source container to a destination container and pumping vapor from said destination container to said source container, said portable fluid exchange system comprising:
- a source container having a substantially hollow interior for retaining liquid and vapor therein;
a liquid and vapor pumping means for pumping liquid from said source container to said destination container and for pumping vapor from said destination container to said source container, and having a liquid inlet, a liquid outlet, a vapor inlet and a vapor outlet;
wherein said liquid inlet and said vapor outlet of said liquid and vapor pumping means are connected in fluid communication with said substantially hollow interior of said source container;
liquid delivery means for delivering liquid from said liquid and vapor pumping means to said destination container;
vapor delivery means for delivering vapor from said destination container to said liquid and vapor pumping means; and
,a selectively controllable actuation mechanism for actuating said liquid and vapor pumping means to thereby concurrently pump liquid from said liquid and vapor pumping means through said liquid outlet and vapor into said liquid and vapor pumping means through said vapor inlet, and concurrently pump vapor from said liquid and vapor pumping means through said vapor outlet and liquid into said liquid and vapor pumping means through said liquid inlet.

Abstract
A portable fluid exchange system comprises a source container, a liquid and vapor pump for pumping liquid from the source container to the destination container and for pumping vapor from the destination container to the source container. The liquid inlet and vapor outlets of the liquid and vapor pump are connected in fluid communication with the source container. A liquid delivery hose delivers liquid from the pump to the destination container. A vapor delivery hose delivers vapor from the destination container to the pump. A selectively controllable actuation mechanism actuates the liquid and vapor pump to thereby concurrently pump liquid from the liquid and vapor pump through the liquid outlet and vapor into the liquid and vapor pump through the vapor inlet, and concurrently pump vapor from the liquid and vapor pump through the vapor outlet and liquid into the liquid and vapor pump through the liquid inlet.
