摘要： An introduction flow channel (51) configured to guide a first fluid (G1) toward an impeller (3), an intermediate suction flow channel (62) adjacent to the introduction flow channel (51) and configured to guide a second fluid (G2) toward the impeller (3), and a curved flow channel (52) connected to downstream sides of the introduction flow channel (51) and the intermediate suction flow channel (62) are defined. The curved flow channel (52) extends so that an inner surface is curved from a position of connection with the introduction flow channel (51) toward one side in the direction of the axial line (O). The diaphragm includes a flow-regulating vane (54) that is provided in the introduction flow channel (51) to regulate the first fluid (G1) to flow along the radial direction; and a partition wall (9) that partitions the introduction flow channel (51) and the intermediate suction flow channel (62) in the direction of the axial line (O). A radially inner end portion (9c) of the partition wall (9) is located further on a radially inner side than a radially outer end portion (54d) of the flow-regulating vane (54), and further on a radially outer side than a boundary (F) between the introduction flow channel (51) and the curved flow channel (52).

摘要： The present invention includes a plurality of blades (40) that are provided at intervals in a circumferential direction on a side of a surface of a disk (30) which is rotated around an axis (O) and is directed in a direction of the axis (O). Each of the blades (40) has a primary blade (50) which extends to a rear side in a rotation direction (R) as the primary blade (50) goes from an inner side toward an outer side in a radial direction and of which a rear edge (52) is positioned on the inner side of an outer circumferential edge portion of the disk (30) in the radial direction; and a secondary blade (60) which is provided at intervals on a side in front of the primary blade (50) in the rotation direction (R), of which a front edge (61) is positioned on the outer side of a front edge (51) of the primary blade (50) in the radial direction, and of which a rear edge (62) is positioned in the outer circumferential edge portion of the disk (30).

摘要： A seal mechanism (20A) is disposed on an outer circumferential side of a rotor (2) extending along an axis (O) to perform sealing between the seal mechanism and the outer circumferential surface (2a) of the rotor (2). The seal mechanism (20A) includes a main body portion (21A) having a cylindrical shape, and into which the rotor (2) is inserted; and a plurality of hole portions (22) formed on an inner circumferential surface of the main body portion (21A) to face an outer circumferential surface of the rotor (2). The hole portions (22) are within a range in which a hole depth h is equal to or smaller than a hole diameter d.
