15 ABSTRACT of the DISCLOSURE A vacuum flush water closet having the bowl, rim and pedestal made of china. The water closet has a self contained flushing water dispensing valve and sewage discharge valve control sys- tem,operatively mounted around and under the bowl. The water closet is secured to the floor by use of a base mounting plate. The sewage discharge valve is fixedly secured to the underside of the bowl and the said valve is manually opened and spring closed. Flushing water is supplied through a flexible flush tube mounted around the underside of the upper rim of the bowl. The flushing water is directed by a vacuum operated water dis- pensing valve. The operation of the water dispensing valve is controlled by a 3-way vacuum switch. The sewage discharge valve is manually operated by a foot pedal mounted below and in front of the bowl. The duration of the sewage discharge valve opening time is controlled by the manual operation and release of the foot pedal. The flushing water volume is limited by a programmed operation of the water dispensing valve and operates independently of the sewage discharge valve opening time. (15 Claims 8 Drawings)
