Abstract

See full text

An apparatus for pressure assisted flush toilets that comprises an air tight enclosed flush tank, a feed valve, a volume control device and a flush valve. The flush tank is normally empty when it is not in use. A push on the feed valve starts a flush cycle by feeding the flush tank with pressurized supply water. The incoming feed water fills the flush tank and at the same time compresses the entrapped air therein. When the tank is filled to the desired volume, the volume control device triggers to close the feed valve and opens the flush valve. Then the pressure of the compressed air in the flush tank discharges the water to the toilet bowl. The discharging water stream from the flush tank cleans the toilet bowl. After the flush the flush tank remains empty until next use.
