Abstract
A liquid siphon including a tank and a pair of concentric shells within the tank. One end of the external-most shell has an enlarged bell part formed thereon. A deformable gasket is retained against an interior portion of the bell part to close the same. A passageway in the bell part communicates the interior thereof with the outside surface and is closed by the gasket when the same is deformed by priming the siphon.
