Abstract
A centrifugal compressor includes a rotor shaft including an impeller and a casing including a suction port and a discharge port. The casing includes a diaphragm that covers the rotor shaft, an outer casing that covers the diaphragm, a discharge scroll that guides a working fluid discharged from the impeller to the discharge port, and a flow path forming member including a scroll outer circumferential surface that is located on an outer side in a radial direction and faces an inner side in the radial direction in the discharge scroll. The rotor shaft and the diaphragm form a bundle that is accommodated in the outer casing in an insertable and removable state. The flow path forming member is formed to have an outside diameter smaller than an outside diameter of the bundle in the radial direction, extends in a circumferential direction, and is fixed to the diaphragm from an axial direction.
