Patent abstract
A system operating in an environment under a vacuum draw in which liquid accumulates utilizes the weight of the liquid to discharge the liquid from the system. The system includes a first holding tank and a second holding tank interconnected by a liquid passageway and a pressure equalization passageway. A number of valves are provided for controlling flow into and out of the second holding tank. The valves are operated in a sequence to use gravity to bring accumulating liquid from the first holding tank to the second holding tank in the vacuum environment, and then to discharge the liquid from the second holding tank to the environment outside of the system.
