ABSTRACT:
Pivoted flap valves are positioned at different angles by valve seats formed on a flush valve body on opposite sides of a vertical axis extending through a lower outlet section of the valve body. Flexible actuating elements depending at different angles from the flush lever, control opening of the flap valves in a one- or two-stage flush operation in response to displacement of the flush lever in one direction.
