Non recirculating method of disposing of waste products for aircrafts

摘要

A method of flushing a toilet for aircraft or the line using vacuum and pressure, in which there is a toilet or other waste receiving bowl, a waste the holding tank, and a valve means for opening or closing the drain line. A vacuum is created in the waste holding tank and the drain line. The drain line is closed or opened by the action of the valve means. In the method the valve means is actuated by vacuum to open the drain line to connect the bowl to the holding tank to apply vacuum on the bowl to suck the contents from the bowl and deliver it to the holding tank. When the bowl has been emptied, pressure is applied to the valve means for closing the drain line to again build up vacuum in the system for subsequent operation.
