Abstract
The invention relates to a rotor for an axial flow pump for conveying a fluid having an axis of rotation and having an impeller blade which has at least one part surface which extends transversely to the axis of rotation and beyond it, wherein the impeller blade has throughgoing webs or a network of webs which connect a different marginal regions of the impeller blades to one another. A good compressibility is hereby achieved in the radial direction with high stability during operation.

A compressible rotor for an axial flow pump for conveying a fluid having an axis of rotation and having an impeller blade which has at least one part surface which extends transversely to the axis of rotation and beyond it, wherein the impeller blade has webs which each, individually or as a network, connect one or more respective further webs forming a respective margin of the impeller blade to one another in different marginal regions of the impeller blades, wherein the connecting webs and the further webs, which form the margin of the impeller blade, comprise the same material.
A compressible rotor for an axial flow pump for conveying a fluid having an axis of rotation and having an impeller blade, wherein the impeller blade is made neckless as a body flat with respect to its contour which is spirally rotated about an axis.
