The invention relates to a fluid pump, in particular to a liquid pump having a rotor (18) with at least one rotor blade (20, 21) 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 simple compressibility and expandibility 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 (23) during a rotation of the rotor during pump operation.
L'invention concerne une pompe à fluide, en particulier une pompe à liquide comportant un rotor (18) avec au moins un aubage de rotor (20, 21) pour transporter le fluide, le rotor ayant un diamètre variable entre un premier état compact et un deuxième état élargi. Afin de réaliser simplement la fonctionnalité de compression et d'élargissement du rotor de la pompe, l'invention comprend au moins un aubage de rotor déformable entre un premier état dans lequel l'aubage se trouve dans l'état compact du rotor et un deuxième état dans lequel l'aubage se trouve dans l'état élargi du rotor à l'aide d'une contrepression de fluide (23) lors de la rotation du rotor pendant le fonctionnement de la pompe.
