サイフォン
From [i]Oxford Dictionaries Online[/i]: A tube used to convey liquid upwards from a reservoir and then down to a lower level of its own accord. Once the liquid has been forced into the tube, typically by suction or immersion, flow continues unaided.

For so-called a syphon coffee maker, use [[coffee maker]] instead.
