PROBLEM TO BE SOLVED: To provide a fluid machine capable of performing compression and expansion of fluid in phases by rotation of single movable scroll member and capable of miniaturizing each scroll member. SOLUTION: Since a first compression chamber P1 and a second compression chamber P2 are included, compression and expansion of refrigerant can be performed in phases by rotation of the single movable scroll member 20. A connecting member 50 connects an outer circumference surface side of the movable scroll member 20 and an eccentric part 40a of a drive shaft 40. When the drive shaft 40 rotates, the movable scroll member 20 performs predetermined rotation via the connecting member 50, and when the movable scroll member 20 performs the predetermined rotation, the drive shaft 40 rotates via the connecting member 50. Consequently, it is not necessary to insert the drive shaft 40 into scroll projections 10a, 20a, 20b, 30a of each scroll member 10, 20, 30. COPYRIGHT: (C)2007,JPO&INPIT
