As shown in FIG. 1, since an annular space is formed by the inner surface of the cylindrical closed container 20 and the outer surface of the cylindrical portion of the partition plate 21, the oil flowing from the inflow pipe 30 together with the refrigerant gas flows into the closed container 20. The gas flows in and turns along with the flow of the gas refrigerant in the annular portion. Accordingly, the oil droplets swirl together with the gas refrigerant, and the oil droplets having a high density adhere to the inner surface of the closed container 20 due to the action of the centrifugal force, are separated, flow down, and accumulate in the lower portion of the closed container 20. The gas refrigerant flows into the closed vessel 20 and turns around the annular portion, and then flows into the outflow pipe 3 through the opening 21 a of the partition plate 21.

【発明の効果】この発明に係る油分離器は、筒状の密閉
容器内面と仕切り板の筒状部外面とにより環状の空間を
形成しているため、流入管から冷媒ガスと共に流入する
油は密閉容器へ流入し、環状部をガス冷媒の流れととも
に旋回することとなり、遠心力の働きで密度の大きい油
滴は密閉容器内面に付着させて分離することができる。According to the oil separator of the present invention, the annular space is formed by the inner surface of the cylindrical airtight container and the outer surface of the cylindrical portion of the partition plate. After flowing into the closed container, the annular portion is swirled with the flow of the gas refrigerant, and the oil droplets having a high density can be separated from the inner surface of the closed container by the action of centrifugal force.
【００３４】また、流入管より流入した冷媒ガスと油と
が旋回し流入管細孔部よりその一部が徐々に流出するよ
うにしていることと、流入管出口から流出する冷媒ガス
速度が十分低下するために、効率良く油を分離すること
できる。Further, the refrigerant gas and the oil flowing from the inflow pipe are swirled so that a part thereof gradually flows out of the inflow pipe pore portion, and the speed of the refrigerant gas flowing out of the inflow pipe outlet is sufficient. Due to the decrease, oil can be separated efficiently.
【００３５】また、流入管より流入する冷媒ガスと油は
容器下部より流入して、開口部より密閉容器の内面に当
てられることにより、油が密閉容器の内面に付着し分
離、また冷媒ガス流速が低下することにより密度差によ
り分離することができる。The refrigerant gas and oil flowing from the inflow pipe flow from the lower part of the container and are applied to the inner surface of the closed container through the opening, whereby the oil adheres to the inner surface of the closed container and is separated. Can be separated by density difference.
【００３６】また、仕切り板の筒状部内部に油分離部材
を設け、小さな油滴を油分離材で捕捉するため分離効率
がさらに高められる。Further, since an oil separating member is provided inside the cylindrical portion of the partition plate and small oil droplets are captured by the oil separating material, the separating efficiency is further improved.
【００３７】また、油分離材を通過する冷媒ガス速度が
整流板流により均一化されるため油滴の油分離材での捕
捉される効率を高くできる。Further, since the velocity of the refrigerant gas passing through the oil separating member is made uniform by the flow of the flow regulating plate, the efficiency of catching oil droplets by the oil separating member can be increased.
