ME 644 Final Term Project

A flushometer is a metal water-diverter that uses an inline handle to flush toilets or urinals. It was invented by William Elvis. "A diaphragm separates a pressure chamber from the main water supply. A narrow passageway leads from the main water supply into the pressure chamber. It is the narrowness of this passage that meters the flow by slowing repressurizing of the pressure chamber after the action of a flush. The diaphragm technology allows the flush valve to open and let water into the bowl. A main cylinder valve operates up and down. A groove in this cylinder allows water from the main supply to flow through when it is in a mid position. The valve is shut off at both its top and bottom positions. A second valve, placed within the main cylinder valve, releases the water in the topmost pressure chamber when the flush lever is activated, sending the main cylinder valve shooting upwards. The topmost pressure chamber slowly refills through its narrow passageway, pushing the valve cylinder back down gradually.
