Patent ID: 8615822

Claim:
An air activated toilet flush system, comprising: a toilet bowl; a reservoir; a fluid conduit between the reservoir and the toilet bowl; a system for supplying water into the reservoir, the system comprising a fill valve activated by the height of water in the reservoir; and a system for supplying ambient air into the reservoir, wherein a supply of ambient air into the reservoir causes fluid to flow from the reservoir through the fluid conduit and into the toilet bowl, and wherein the system for supplying ambient air into the reservoir can be operated in different flush profiles, and (i) wherein the system for supplying ambient air into the reservoir comprises an open air path therethrough permitting free passage of air between the reservoir and the ambient environment when the system for supplying ambient air is turned off, and (ii) wherein the system for supplying ambient air overcomes the free passage of air in the open air path between the reservoir and the ambient environment and pushes ambient air into the reservoir when the system for supplying ambient air is turned on, and (iii) wherein ambient air pushed into the reservoir can only exit the reservoir back through the system for supplying ambient air into the reservoir such that the reservoir has only one combined air inlet/outlet when the water level in the reservoir is above the bottom end of the fluid conduit; and wherein the water level in the reservoir is higher than the water level in the toilet bowl.
