Abstract
A toilet room flush valve for use in flushing toilets and urinals includes a valve body having a water inlet and a water outlet. There is a valve within the body for controlling flow between the inlet and the outlet. A handle is mounted on the valve body for pivotal movement about a handle axis to operate the valve. There is an assembly mounted on the valve body for causing sensor initiated movement of the handle, which assembly includes a motor driven handle interface pivotally mounted on the valve body for movement about the handle axis and having a portion thereof positioned to contact and pivotally move the handle. A drive motor is mounted on the valve body and connected to the interface to cause pivotal movement thereof. A battery for operating the drive motor is connected to a sensor mounted on the valve body, with the sensor being connected to cause the application of battery power to the drive motor.
