Abstract
This centrifugal rotary machine includes an impeller having a disk, blades, and a cover. The centrifugal rotary machine further includes a casing which accommodates the impeller radially inward and forms a gap between an outer circumferential surface of the cover and the casing. The centrifugal rotary machine further includes a sealing device which seals the gap. The casing includes an end wall surface which is disposed to face one axial side of a cover end surface facing one axial side of the cover, extends in the radial direction and forms a radial flow path between the end wall surface and the cover end surface. The casing further includes a foreign matter introduction path which is formed inside the casing and communicates with a radially outer side of the radial flow path.
