Description
上記課題を解決するリザーブタンクは、気液分離部（１００）と、流入部（１２０）と、流出部（１３０）と、筒状の突出部（１１０）と、を備える。気液分離部は、所定の軸線を中心に有底筒状に形成される。流入部は、気液分離部に設けられ、気液分離部の内部に冷却水を流入させる。流出部は、気液分離部に設けられ、気液分離部の内部から冷却水を流出させる。突出部は、気液分離部の内部において底壁部（１０１）から所定の軸線に沿って延びるように形成される。気液分離部の内周面と突出部の外周面との間に形成される隙間により環状流路（ＦＰ）が形成されている。気液分離部の内面において流入部に連通される開口部を流入開口部（１０３）とし、気液分離部の内面において流出部に連通される開口部を流出開口部（１０４）とするとき、流出開口部は、所定の軸線に沿った方向において流入開口部よりも気液分離部の底壁部側に配置され、流入開口部は、所定の軸線に沿った方向において突出部の先端部よりも気液分離部の底壁部側に配置されている。突出部の先端部には、突出部の内部空間を気液分離部の内部空間に連通させる開口部が形成されている。突出部の内部空間は、開口部を通じて気液分離部の内部空間のみに連通されている。流出開口部及び流入開口部は、突出部の内部空間に連通されず、且つ環状流路のみに連通されるように気液分離部に設けられている。 A reserve tank that solves the above problems includes a gas-liquid separation section (100), an inflow section (120), an outflow section (130), and a cylindrical projecting section (110). The gas-liquid separation part is formed in a cylindrical shape with a bottom centering on a predetermined axis. The inflow part is provided in the gas-liquid separation part and causes cooling water to flow into the gas-liquid separation part. The outflow part is provided in the gas-liquid separation part and causes the cooling water to flow out from the inside of the gas-liquid separation part. The projecting portion is formed to extend along a predetermined axis from the bottom wall portion (101) inside the gas-liquid separating portion. An annular flow path (FP) is formed by a gap formed between the inner peripheral surface of the gas-liquid separation portion and the outer peripheral surface of the protruding portion. When an opening on the inner surface of the gas-liquid separation section that communicates with the inflow section is defined as an inflow opening (103), and an opening that communicates with the outflow section on the inner surface of the gas-liquid separation section is defined as an outflow opening (104), The outflow opening is arranged closer to the bottom wall portion of the gas-liquid separator than the inflow opening in the direction along the predetermined axis, and the inflow opening is located closer to the tip of the protrusion in the direction along the predetermined axis. are arranged on the bottom wall side of the gas-liquid separation section. An opening is formed at the distal end of the protrusion, which communicates the internal space of the protrusion with the internal space of the gas-liquid separation section. The internal space of the protruding portion communicates only with the internal space of the gas-liquid separation portion through the opening. The outflow opening and the inflow opening are provided in the gas-liquid separation section so as not to communicate with the inner space of the projection but only with the annular flow path.
