Abstract: This invention comprises an improved hydraulically operated flush valve for toilet flush tanks and similar devices. Its main components are a cylinder and piston assembly positioned with its longitudinal axis directly above and vertically aligned with the vertical axis of the outlet or flush tube of the flush tank. The moveable piston within the fixed cylinder acts as the moving and sealing element of the flush valve. By means of an inner valve connected to the flush tank operating lever hydraulic force is caused to lift the piston thereby opening the flush valve. There is no direct mechanical connection between the operating arm and the flush valve, and there are no chains or hinges. There is a positive permanent flush valve alignment and a minimum of friction. In addition, the amount of water used per flushing action can be regulated to prevent water and energy wastage.

Abstract: The preferred embodiment of the invention disclosed in this application includes a building module having at least one compartment therein in which is contained a toilet system for bacteriologically breaking down solid waste and paper to provide a relatively pure liquid effluent. The toilet communicates with a flush tank into which the effluent is discharged and which communicates with a pump for pumping the effluent to an evaporator for removing excess effluent from the toilet system. Preferably the evaporator utilizes the effluent as a heat exchange medium for heating or cooling air discharged to each toilet compartment which air is circulated back to the atmosphere through a vent opening to help remove odors from the compartment. The evaporator may be arranged to aerate the effluent which is then discharged back to the flush tank so that it can be used to flush the toilet and enhance the biological breakdown of waste.
