To discharge separated oil from a silencer efficiently, and enhance pressure resistance, in the silencer having an oil separation function.SOLUTION: A silencer (80 (80A, 80B, 80C)) comprises a silencer housing (82) having a refrigerant inflow port (84), a refrigerant outflow port (86), and an oil outflow port (88). At least a portion of oil is separated from a refrigerant (R) containing mist-like oil having flowed into the silencer housing through the refrigerant inflow port, the separated oil is discharged from the silencer housing through the oil outflow port as liquid oil (O), and then a refrigerant (R) from which at least the portion of oil has been separated is discharged from the silencer housing via the refrigerant outflow port. The silencer housing is formed into a substantially spherical shape. The silencer is preferably provided downstream of a compressor in a vehicular refrigeration cycle device.SELECTED DRAWING: Figure 3

    【課題】オイル分離機能を有する消音器において、分離したオイルを消音器から効率良く排出するとともに、耐圧性を高める。【解決手段】消音器(80(80A,80B,80C))は、冷媒流入ポート(84)と、冷媒流出ポート(86)と、オイル流出ポート(88)とを有する消音器ハウジング(82)を備える。冷媒流入ポートを介して消音器ハウジング内に流入してきたミスト状のオイルを含む冷媒(R1)から少なくとも一部のオイルが分離され、分離されたオイルが液状のオイル(O)としてオイル流出ポートを介して消音器ハウジングから排出され、オイルの少なくとも一部が分離された冷媒(R2)が冷媒流出ポートを介して消音器ハウジングから排出される。消音器ハウジングは略球形である。消音器は、好ましくは、車両用冷凍サイクル装置において圧縮機の下流側に設けられる。【選択図】図3
