ABSTRACT:
A fluid flow machine has at least one disc-shaped rotor provided with flow channels for a flow medium, the intake and exit openings of said channels being located axially of said rotor. The distance of the intake openings from the axis of rotation is different from that of the exit openings. Each flow channel has a radially outer and a radially inner deflector elbow having two legs extending at an angle of about 90.degree. relative to one another, one leg of one elbow leading to an intake opening and one leg of the other elbow leading to the respective exit opening. The respective other legs of the two elbows are aligned with a substantially radial connecting section interconnecting the two deflector elbows. A higher pressure drop per stage is obtained by providing that the intake openings as well as the exit openings are located at the same axial surface of the rotor.
