FLUSH VALVE HANDLE ASSEMBLY A flush valve handle assembly includes a collar adapted to be attached to a flush valve body. There is an opening in the collar and a flush valve handle extends through the opening. A piston is movable within the collar and in contact with that portion of the flush valve handle extending through the opening. An operating rod is attached to and movable with the piston and is integral with a flexible diaphragm which is in sealing contact with the flush valve body. A spring member is attached to the piston and is effective to urge the operating rod and piston to a normally unoperated position. |
