PROBLEM TO BE SOLVED: To provide an air separator and a gas-liquid separator which simplify a structure and can effectively remove air bubbles in a liquid at low cost.SOLUTION: A gas-liquid separator includes: an air separator which has a storage chamber 35 whose cross section is formed into a substantially circular shape or a substantially annular shape, an inflow port 31 for flowing a liquid in a direction that is lateral and is deviated from a center point of a cross section, into the storage chamber 35, a first outlet port 32 for flowing out the liquid having reduced air bubbles from the storage chamber 35, and a second outlet port 33 for flowing out air separated from the liquid from the storage chamber 35 first piping 11 that connects the first outlet port 32 and a first opening 41 provided below a tank 40 and flows in the liquid having flowed from the first outlet port 32 from a first opening 41 into the tank 40 and second piping 12 that connects the second outlet port 33 and a second opening 42 and flows in air having flowed out from the second outlet port 33 from the second opening 42 into the tank 40.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】構造を簡素化して低コストで液中の気泡を有効に取り除くことができるエアーセパレータおよび気液分離装置を提供する。【解決手段】横断面が略円形あるいは略円環形状に形成された収容室35と、収容室35に、横向きであって横断面の中心点から逸れる向きに液を流入させる流入口31と、気泡が減じられた液を収容室35から流出させる第1流出口32と、液から分離した空気を収容室35から流出させる第2流出口33とを有するエアーセパレータ、第1流出口32と、タンク40の下部に設けられている第1開口41との間を繋ぎ、第1流出口32から流出した液を第1開口41から40タンク内に流入させる第1配管11、および、第2流出口33と第2開口42との間を繋ぎ、第2流出口33から流出した空気を第2開口42からタンク40内に流入させる第2配管12とを備えた。【選択図】図1
