Abstract
A fluid-flow machine for compressing or expanding a compressible medium is described, having a rotor on which there is arranged perpendicularly to the rotor axis at least one moving-blade row, the individual moving blades of which have moving-blades ends, which are free on the radial side and face the inner wall of a casing, surrounding the rotor, in a freely movable manner, through the interior space of which casing the compressible medium flows axially relative to the rotor axis. An annular-passage system is open to receive the compressible medium on either side of the moving-blade row and the flow in the interior of the casing, and in a modified form may have surface contours on the ends of the blades to create pressure conditions which correspond approximately to the static pressure conditions at the opposite sides of the blades.
