ABSTRACT:
A pressurized flushing assembly mounted in the tank of a toilet for providing a rapid and thorough flushing of the toilet bowl with a low volume of water. The assembly includes a water storage tank defining an outlet aperture communicating with the cistern drain and a valve assembly disposed within the storage tank for opening and closing the outlet aperture. The valve assembly communicates with a supply of pressurized water for directing water under pressure into the storage tank to compress the ambient air therein. The valve assembly includes a housing, a control valve, a fluid control piston, a cistern drain valve and a push button actuator for opening the control valve. Opening the control valve allows water within the valve assembly to flow therethrough and from the valve assembly, creating a pressure drop within the housing above the fluid control piston causing the fluid control piston rapidly to rise and allowing water to flow past the piston and from the valve assembly. The raising of the piston creates a pressure drop in the housing below the piston, causing the the cistern drain valve disposed therebelow rapidly to rise off the storage tank outlet aperture whereupon the compressed air within the storage tank drives the water therein through the tank's outlet aperture to effect a flushing of the toilet.
