Abstract
A conveying member, especially a rotor or stator, for conveying a flowable, preferably gaseous medium, comprises a plurality of blades (S-S) arranged following each other with a circumferential distance in a circumferential direction (U) around a central axis (A). Either a first circumferential distance (a) or a second circumferential distance (b) differing from the first circumferential distance (a) is provided between a blade and a respective blade following it in the circumferential direction (U) in a group of blades directly following each other in a circumferential direction (U), which the group comprises at least some of the blades (S-S). The first circumferential distance (a) is provided between at least two blades (S-S) located directly adjacent to one another, and the second circumferential distance is provided between at least two blades (S-S) located directly adjacent to one another.
