Abstract
A sensor-operated battery powered flush valve for a toilet device includes a valve body having a water inlet and a water outlet. A diaphragm valve movable within the valve body controls the flow of water between the inlet and the outlet. A latching solenoid is mounted within the valve body and controls movement of the diaphragm between open and closed positions. A battery is mounted to provide the power for the latching solenoid. An infrared sensor connects the battery to the latching solenoid to cause the solenoid to move the diaphragm to a valve open position. A magnetically-operated switch is positioned within the valve body and a magnet carried by the diaphragm will cause the switch to close when the diaphragm moves to a valve open position. Closure of the magnetic switch causes the solenoid to move to a position in which the diaphragm will close flow between the inlet and the outlet of the flush valve.
