摘要： Provided is a centrifugal compressor which can be stably operated in a wide range by increasing an operating range on a low-flow-rate side and on a high-flow-rate side, with a simple structure of combining a recirculation flow path and a reverse swirling flow generation unit including fixed blades, without providing a complicated movable mechanism for a guide vane. A compressor 3 includes: a compressor casing 9 including an air intake port 13 open in a direction of a rotational shaft 5 of the compressor 3 and an air intake path 11 connected to the air intake port 13, an impeller 7 which is disposed rotatable about the rotational shaft 5 and compresses intake gas flowed in through the air intake port 13, a reverse swirling flow generation unit 41 which generates a swirling flow of the intake gas, flowed in through the air intake port 13, in a direction opposite to a rotation direction of the impeller 7, and a recirculation flow path 25 which communicates between an outer periphery of the impeller 7 with the air intake path 11 on an upstream side of the impeller 7. The reverse swirling flow generation unit 41 includes reverse swirling fixed blades 43 which generates a swirling flow at a predetermined angle with respect to the direction opposite to the rotation direction of the impeller 7.
