91/156 ENHANCED VACUUM ASSISTED TOILET ABSTRACT OF THE DISCLOSURE A water saver toilet is provided, of the type that applies a vacuum to the toilet bowl outlet to assist flushing, which can apply a considerable vacuum in a toilet of low height. The vacuum source (60, Fig. 1) is coupled to the pressured water inlet (44) that supplies water under a pressure of a plurality of pounds per square inch to fill the tank after each flushing, with the pressure of the water being used to energize the vacuum source. A prior art type of tank inlet valve (16) is used, of the type that has a float (42) that drops and opens the valve when the tank water level drops at the beginning of flushing. The opening valve directs pressured water through a conduit (72) to the vacuum source to energize it to apply a vacuum shortly after the tank water level drops. The vacuum source includes an actuator (76, Fig. 3) with a plunger (84) that is lifted by pressured water flowing into the actuator, the plunger lifting a diaphragm (90). to produce a vacuum in a chamber (92) that is coupled to the toilet bowl outlet.
