Title: CRUCIFORM WATER DISTRIBUTION VALVE FOR AIRCRAFT GALLEY PLUMBING SYSTEM
Abstract:
A four-way distribution valve is provided that allows for efficient filling and drainage of a potable water supply and waste system including a potable water distribution manifold and water filter in a commercial aircraft galley. The water distribution valve includes a cruciform manifold having a filter drain port connected to the water filter, two supply manifold ports connected to the potable water distribution manifold, and a drainage discharge port. A rotary closure element within the cruciform manifold actuates in accordance with four selectable filling and discharge modes for the valve to fill and drain potable water in the potable water supply and waste system. As a result, the valve can be used to fill the potable water supply system with potable water before a flight, and to selectively drain potable water from the potable water distribution manifold, the water filter, or both after a flight, all through the same valve.
