Abstract
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.

A fluid pump, comprising a rotor with at least one rotor blade for conveying fluid, the rotor being variable with respect to its diameter between a first compressed state, and a second expanded state, wherein the at least one rotor blade transitions from the first compressed state to the second expanded state by deformation and further wherein the at least one rotor blade has a leading side and a trailing side in a direction of movement during conveying pump operation, wherein the at least one rotor blade includes a plurality of shaped elements on the trailing side, wherein the plurality of shaped elements support the at least one rotor blade and prevent further deformation of the rotor blade during operation of the rotor in the second expanded state.
