Provided is a radial turbine in which fluids having a plurality of pressures are handled with a single or integrated turbine wheel and whose cost is reduced by decreasing the number of parts. A radial turbine (100) includes a radial turbine wheel (15) that is provided with a main pathway (26) in which blade height progressively increases while curving toward an axial direction from a radial direction, that converts swirling energy from a fluid that flows into the main pathway (26) from a main inlet (21) on an outer circumferential side and having a flow in the radial direction as the main component thereof into rotational motive power, and that expels the fluid in the axial direction, wherein a sub-inlet (29) into which flows a fluid whose pressure (P2) differs from pressure (P1) of the fluid supplied from the main inlet (21) is formed on a shroud side of the radial turbine wheel (15) at a position separated from the main inlet (21) in the radial direction and the axial direction; and a blade shape that forms the sub-inlet (29) is such that, in a plane orthogonal to the axial line of the radial turbine wheel (15), a center line of the blade (19) is inclined at a predetermined angle toward the rotation direction with respect to the radial direction. |
