ABSTRACT:
A pressurized flushing apparatus for commodes in which low volumes of pressurized water are used for flushing. The apparatus includes a pressurizeable tank having a closed water outlet. The tank is pressurized by the introduction of pressurized water into the tank until a pressure of between 8 and 25 psi is achieved. Within the tank is a bellows to which a plug is attached to one end for closing the water outlet. A restrictable open channel connects a pressure zone above the water in the tank with an internal chamber located within the bellows. The open channel is consticted by a needle valve which controls the rate at which the pressure within the pressure zone and the internal chamber are equalized. When the pressure within the internal chamber is reduced to ambient pressure, the bellows will collapse and withdraw the plug from the water outlet. When this occurs, the pressurized water within the tank will be forced out of the tank and into the toilet bowl. Fresh water will then be introduced and the bellows will expand at a rate controlled by the needle valve. When the bellows is fully expanded, the water outlet is closed and the tank is refilled with water. The commode is now ready for the next flushing sequence.
