To provide a compressor capable of suppressing the leakage of fluid from a second chamber to a first chamber via the radial outside of a vane.SOLUTION: A compressor 10 includes a rotary shaft 12, a rear rotor 80 having a rear rotor surface 90, an intermediate wall part 51 having a second wall face 53 opposed to the rear rotor surface 90 in an axial direction Z, and a vane 100 abutting on the rear rotor surface 90 in the state of being inserted into a vane groove formed in the intermediate wall part 51, and adapted to be moved in the axial direction Z with the rotation of the rear rotor 80. The compressor 10 further includes a first rear compression chamber and a second rear compression chamber in which volumetric changes are caused by the vane 100 along with the rotation of the rear rotor 80, the compressor 10 also including an oil supply part 116 for supplying oil separated by an oil separator 115 to a vane outside end face as the end face on the outside in a radial direction R of the vane 100.SELECTED DRAWING: Figure 1 【課題】ベーンの径方向外側を介して第２室の流体が第１室に向けて漏れることを抑制できる圧縮機を提供すること。【解決手段】圧縮機１０は、回転軸１２と、リアロータ面９０を有するリアロータ８０と、リアロータ面９０と軸方向Ｚに対向する第２壁面５３を有する中間壁部５１と、中間壁部５１に形成されたベーン溝に挿入された状態でリアロータ面９０と当接しており、リアロータ８０の回転に伴って軸方向Ｚに移動するベーン１００と、を備えている。圧縮機１０は、リアロータ８０の回転に伴ってベーン１００によって容積変化が生じる第１リア圧縮室及び第２リア圧縮室を備えている。ここで、圧縮機１０は、オイルセパレータ１１５によって分離されたオイルを、ベーン１００における径方向Ｒ外側の端面であるベーン外側端面に供給するオイル供給部１１６を備えている。【選択図】図１
