To provide an underwater vehicle capable of reversibly increasing/decreasing ballast in order to repeat sinking, underwater navigation, and floating as well as being suitable for underwater navigation in deep sea.SOLUTION: An underwater vehicle includes: a tank 2 loaded on a machine body and having a gas unit and a volume variable liquid unit formed inside an inner space with a prescribed volume; and a water injection/drainage system 5. The water injection/drainage system includes: a reciprocating pump 6 having a pump suction opening 61 and a pump discharge opening 62; a water injection/drainage piping 7 for forming a water injection path from an intake opening for liquid to a liquid unit entrance/exit opening on a liquid unit 4 and the water drainage path from the liquid unit entrance/exit opening 21 to an outlet of liquid so that the flow of liquid passing the reciprocating pump is always one way from the pump suction opening to the pump discharge opening; and a path switching unit 9 for switching the flow path of the liquid flowing through the injection/drainage piping.SELECTED DRAWING: Figure 2

    【課題】沈降・潜航・浮上を繰り返すためにバラストを可逆的に増減可能な水中航走体であって、深海の潜航に好適なものを提供する。【解決手段】水中航走体は、機体に搭載され、所定の容積を有する内部空間に気体部と体積可変な液体部とが形成されたタンク2と、注排水システム5とを備える。注排水システムは、ポンプ吸入口61及びポンプ吐出口62を有する往復ポンプ6と、往復ポンプを通過する液体の流れが常にポンプ吸入口からポンプ吐出口への一方向となるように、液体の取水口から液体部4に開口した液体部出入口への注水流路及び液体部出入口21から液体の放水口への排水流路を形成する注排水配管7と、注排水配管を流れる液体の流路を切り替える流路切替部9とを備える。【選択図】図2
