A scroll fluid machine comprises a stationary scroll that has a spiral stationary wrap, and an orbiting scroll that has a spiral orbiting wrap to form a compression chamber between the stationary and orbiting wraps. In the stationary and orbiting wraps, an outer low-pressure pressurizing portion is separated from an inner high-pressure pressurizing portion. A plurality of outlets and inlets are formed in the low-pressure and high-pressure pressurizing portions respectively. At least one of the outlets or at least one of inlets is selectively closed.
