ABSTRACT:
A water supply system for an aircraft is constructed to prevent freeze-up by causing the water to repeatedly flow back and forth between a water supply tank and one or more water displacement tanks. For this purpose, the displacement tank or tanks are connected through a pressurized pipe and through a switch-over valve to a junction between two series connected pressure controllers, preferably closed loop pressure controllers, that connect a source of gas pressure, such as air pressure, to a water tank, which in turn is connected through a water supply pipe to the water displacement containers and to respective faucets. A filling and draining valve is connected to the tank, to the water supply pipe, and to a venting and overflow pipe. A control unit switches the switch-over valve back and forth between a position in which the pressure in the pressure pipe transports the water from the displacement containers into the tank and another position in which the pressure in the tank transports the water from the tank into the displacement containers while some of the air in the displacement containers is vented. Such a back and forth movement prevents freeze-up and avoids the use of downwardly slanted pipe sections that lead to a drainage port. A plurality of displacement containers with respective valves are connected in parallel to each other between the pressure pipe and the water supply pipe.
