Abstract
A cover disk () for a closed rotor of a radial flow machine or diagonal flow machine for defining a flow channel has a wall thickness which has a local maximum along the profile mean line of the meridional cross section of the cover disk between a first front side () and a second front side () of the cover disk. An outer surface () of the cover disk remote of the flow channel has in the area of this local maximum a convex curvature with a radius (R) whose ratio (R/D) to an outer diameter (D) of the rotor is within a range of 0.05 to 0.5 (0.05≦R/D≦0.5).
