ABSTRACT:
A vacuum flush water closet having a bowl and rim which are made from steel stampings covered with chemical resistant procelain. The water closet has a self-contained flushing water and sewage valve discharge control system which is operatively mounted around the bowl and enclosed by an outer shroud made of a molded high impact plastic material. The water closet is shock proof and is mounted on a base plate that may be fixedly secured to a mounting surface, such as a floor or ship's deck. The bowl is mounted on a sewage discharge valve which is spring closed and vacuum opened. Flushing water is supplied through a spray ring mounted around the upper end of the bowl. The flushing water is controlled by a vacuum operated valve. The operation of the flushing water valve and the sewage discharge valve is controlled by a vacuum-gravity timer which is activated by a push button switch mounted at the rear of the bowl rim. The length of the flushing cycle and the sewage discharge cycle is controlled by the vacuum-gravity timer. The flushing cycle takes place in a short time interval and a minimum amount of water is employed for flushing purposes.
