    摘要： The invention relates to a radially compressible and expandable rotor for a pump having at least one impeller blade, wherein the impeller blade has an impeller blade body whose material is elastically deformable as well as at least one stiffening strut which is at least partially embedded in the material of the impeller blade body. The struts are designed suitably in size, shape and arrangement and are integrated in suitable hollow spaces of the impeller blade body for stabilizing the impeller blade. Elements with tensile strength can additionally be provided.

    摘要： The invention relates to a fluid pump, in particular to a liquid pump having a rotor with at last one rotor blade for conveying the fluid, the rotor being variable with respect to its diameter between a first, compressed state and a second expanded state. In order to produce a simple compressibility and expandability of the rotor of the pump, it is provided according to the invention that at least one rotor blade is deformable between a first state which it assumes in the compressed state of the rotor and a second state which it assumes in the expanded state of the rotor by means of a fluid counterpressure during a rotation of the rotor during pump operation.

    摘要： A rotor for a pump has a housing and a rotor, and has at least one blade. The rotor is able to be actuated to rotate about an axis of rotation in order to convey a fluid in the axial or radial direction, and the rotor is able to be deformed in the radial direction between a first, radially compressed state and a second, radially expanded state. At a maximum speed of rotation of the rotor at which the power of the pump is at a maximum, the blade is essentially radially oriented, and/or the rotor has its maximum diameter.
