ABSTRACT:
A fluid-flow machine. At least one substantially disc-shaped rotor has a plurality of fluid-flow channels therethrough. Each fluid-flow channel comprises rectangular shaped inlet and outlet openings on opposite sides of the rotor disposed at different distances from the axis of rotation of said rotor, a tangential inlet channel portion including the inlet opening for receipt of a fluid-flow medium, a tangential outlet channel portion including the outlet opening for discharge of the fluid-flow medium and a circular radial connecting section between the channel portions having curved opposite ends connecting said inlet portion to said outlet portion completely around the perimeter thereof. Each channel portion has a direction, for directing the fluid-flow medium, which has a transverse and an axial component relative to the axis of rotation of the rotor. The axial components are in the same direction and the transverse components are in the opposite direction. The fluid-flow channels are formed so as to transform from the rectangular inlet and outlet channel portions into the curved cross-section in said radial connecting section.
