COMPRESSOR

To provide a compressor which can suppress size enlargement in a radial direction.SOLUTION: A compressor 10 comprises a discharge recess 71 provided at a rotating body ring part 70, located inside a radial direction with respect to a cylinder internal peripheral face 31, and introduced with a compressed fluid which is compressed in compression chambers A4, A5. The compressor 10 also comprises: a discharge port for making the compression chambers A4, A5 and the discharge recess 71 communicate with each other by being opened at rotating body faces 71a, 72a; and a rotating shaft 12 inserted into a rotating body cylinder part 61, and rotating integrally with the rotating body cylinder part 61. The rotating shaft 12 has: an in-shaft passage 171 extending in an axial direction Z and communicating with the discharge chamber A1; and a communication hole 172 for making the in-shaft passage 171 and the discharge recess 71 communicate with each other.SELECTED DRAWING: Figure 4 【課題】径方向への大型化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、回転体リング部７０に設けられ、且つシリンダ内周面３１に対して径方向の内側に位置し、圧縮室Ａ４，Ａ５にて圧縮された圧縮流体が導入される吐出凹部７１を備えている。圧縮機１０は、回転体面７１ａ，７２ａに開口することによって圧縮室Ａ４，Ａ５と吐出凹部７１とを連通させる吐出ポートと、回転体筒部６１の内部に挿入され、当該回転体筒部６１と一体回転する回転軸１２と、を備えている。回転軸１２は、軸方向Ｚに延びて吐出室Ａ１に連通する軸内通路１７１、及び軸内通路１７１と吐出凹部７１とを連通させる連通孔１７２を有する。【選択図】図４
