Abstract
A drop tube employed in the discharge of fuel into a storage tank of the type having an inlet, riser pipe is described. The drop tube a tubular member and an overfill valve. The overfill valve comprises a valve member having open and closed positions which is controlled by a float mounted thereon. The drop tube is insertable through the riser pipe to a position wherein the float displaces the valve member towards its closed position when the fuel in the tank reaches a desired level. A depression in the tubular member receives the float to facilitate insertion of the drop tube through the riser pipe. The valve member is freely pivotal from its open position to its closed position, being displaced thereto by the force of fuel discharged into the tank. A pressure relief valve is provided to reduce the forces on the valve. A bleed valve is also provided for bleeding fuel from above the valve when it is in its closed position. Further mechanism, actuated by the float, close the bleed valve when the level of fuel is at a predetermined height above its desired level.
