Abstract
The invention relates to a rotor for a pump, having at least one blade, the rotor being able to be actuated to rotate about an axis of rotation in order to convey a fluid in the axial or radial direction, the rotor being able to be deformed reversibly elastically in the radial direction between a first, radially compressed state and a second, radially expanded state which the rotor adopts without the effect of external forces, and a third state of the rotor being provided in which, in pumping operation under fluid loading, the rotor is deformed from the first state to beyond the second state.

28. A rotor for a pump comprising:
- the rotor being able to be actuated to rotate about an axis of rotation in order to convey a fluid in the axial or radial direction, the rotor being able to be deformed reversibly elastically in the radial direction between a first, radially compressed state and a second, radially expanded state which the rotor adopts without the effect of external forces, and at least one third state of the rotor being provided in which, in pumping operation under fluid loading, the rotor is deformed from the first state to beyond the second state.

46. A rotor for a pump, comprising at least one blade, the rotor being able to be actuated to rotate about an axis of rotation in order to convey a fluid in the axial or radial direction, the rotor being able to be deformed in the radial direction between a first, radially compressed state and a second, radially expanded state and the blade having, in an operating state, an entry angle of the blade (β

51. A pump, comprising a housing and a rotor situated therein for a pump, having at least one blade, the rotor being able to be actuated to rotate about an axis of rotation in order to convey a fluid in the axial or radial direction, the rotor being able to be deformed in the radial direction between a first, radially compressed state and a second, radially expanded state, and the blade, at the maximum speed of rotation of the rotor, at which the power of the pump is at a maximum, being essentially radially orientated and/or the rotor having its maximum diameter at this speed of rotation.
