Abstract
A battery-powered, sensor-operated flush valve for controlling water flow through a toilet room device such as a urinal or water closet includes a flush valve body with an inlet and an outlet. There is a valve mechanism for controlling flow through the flush valve body. A solenoid is attached to the flush valve body and has a piston which is positioned to contact the valve mechanism relief valve. The solenoid is in circuit with a battery and a sensor whereby a user of toilet room device will cause battery power to be applied to the solenoid coil, which will in turn move the piston to contact the relief valve to institute a flushing operation.
