First Claim
Patent Images
1. A fluid pump comprising:
- at least one impeller blade which is rotatable about an axis of rotation and conveys a fluid in operation; and
comprising a support device which supports the at least one impeller blade in at least one support region, wherein the support device is changeable between a first state in which the at least one impeller blade is radially compressed and a second state in which the at least one impeller blade is radially expanded; and
wherein the at least one impeller blade extends at least partly radially inwardly with respect to the axis of rotation from the at least one support region in the radially expanded state of the at least one impeller blade;
wherein the support device is formed by at least one ring concentrically journalled with respect to the axis of rotation,wherein the at least one ring is designed in meandering form in the peripheral direction.

Abstract
A fluid pump has at least one impeller blade which is rotatable about an axis of rotation and conveys a fluid in operation. The fluid pump has a support device which supports the at least one impeller blade in at least one support region. The support device is changeable between a first state in which the at least one impeller blade is radially compressed and a second state in which the at least one impeller is radially expanded. The at least one impeller blade extends at least partly radially inwardly with respect to the axis of rotation from the at least one support region in the radially expanded state of the blade.
