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.
Claims10
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 compressed state, and an expanded state, wherein the at least one rotor blade deforms as the rotor transitions between the compressed state, and the expanded state, wherein the at least one rotor blade has a leading side and a trailing side with respect to a direction of rotation during conveying pump operation, and wherein the rotor is configured such that when the rotor is rotating during conveying pump operation, a fluid counterpressure is produced counter to the direction of rotation against the leading side of the at least one rotor blade, and wherein the leading side of the rotor blade comprises a first material and wherein the trailing side of the rotor blade comprises a second material, wherein the first material has a predetermined permanent elongation limit wherein the predetermined permanent elongation limit is produced by stretch-resistant fibers embedded in the first material.
