ABSTRACT:
A toilet assembly suitable for use on commercial passenger vehicles, including a bowl for receiving waste and waste outlet tubing connecting the bowl to a vacuum source. A flush valve assembly is provided in the outlet tubing and is selectively openable to connect the vacuum source to the bowl for sucking the waste out of the bowl. A disposable spray ring containing a plurality of holes and selectively coupled to a water source is wedged between the bowl and a separate lip member for dispensing water onto the interior surface of the bowl. The flush valve assembly includes a vacuum chamber with top and bottom vacuum inlet ports, a piston connected to a valve blade movable vertically within the chamber and a flush solenoid openable to selectively connect a second vacuum to the top and bottom inlet ports. The assembly is supported by a novel lightweight composite base having triangular composite legs.
