Insertion tube liquid evacuator system for vapor recovery hose

In a liquid distribution system including a product hose for pumping liquid from a storage tank to a nozzle for transfer to another tank, a vapor recovery hose coaxial with and enclosing said product hose, said vapor recovery hose being connected to the nozzle at one end and a vapor return connection at its other end for returning vapors developed about said nozzle (via a vapor recovery path between said vapor recovery and product hoses) to said storage tank, wherein liquid may back up from said nozzle into said vapor recovery path of said vapor recovery hose and tend to accumulate at a low point thereof, causing blockage of the vapor recovery path of said vapor recovery hose, the improvement comprising:

• tubing means for providing a pathway for evacuating liquid from said vapor recovery hose, said tubing means having one open end located in said vapor recovery path substantially at the liquid accumulation area of said vapor recovery hose;
• and
• pumping means connected to another end of said tubing means for sucking liquid from said vapor recovery hose, and further including means for returning the recovered liquid to said storage tank.

In a liquid distribution system including a plurality of product hoses for pumping liquid from a storage tank to a plurality of nozzles, respectively, for transfer to other individual tanks, respectively, a plurality of vapor recovery hoses coaxial with and enclosing said product hoses, respectively, being connected at one end thereof to individual ones of said nozzles, respectively, said vapor recovery hoses being connected at their other ends to vapor return means for returning vapors developed about said nozzles, respectively, from said nozzles via vapor return paths between said vapor recovery hoses and product hoses, back to said storage tank, wherein liquid overflow from said nozzles into said vapor recovery hoses accumulates at low points thereof, respectively, causing blockage of affected ones of the vapor return paths of said vapor recovery hoses, the improvement comprising:

• a plurality of tubing means each for providing a pathway for liquid, each having an open end located within the vapor return path in the liquid accumulation areas of said vapor recovery hoses, respectively;
• and
• pumping means connected to the other ends of said plurality of tubing means, respectively, for sucking liquid from said vapor recovery hoses via respective ones of said plurality of tubing means.
