A rear housing (5) includes a first path (5d) extended toward a communication hole (2h) of a valve forming plate (2) from a reception chamber (5c). A cylinder block (1) includes a connection part (1f) connected to an external device, an exit space (1e) opening toward the connection part, and a second path (1d) extended toward a communication hole (2h) of a valve forming plate from the exit space. A discharge path (6s) comprises a discharge chamber (5b), a reception chamber (5c), a first path (5d), a communication hole (2h), a second path (1d), and an exit space (1e). A flow path cross-sectional area (S3) of a communication hole (2h) is larger than at least one between a flow path cross-sectional area (S1) of a first path and a flow path cross-sectional area (S5) of a second path. Moreover, high degree of freedom is obtained when a discharge path is designed. |
