Abstract
The ring (5) connected to the ends of the fan blades beyond the axial impeller in the air inlet direction. It has a constantly increasing dia. in the region projecting beyond the impeller (3), starting from the impeller. The ring can be widened to form a nozzle. The ring can cover two thirds of the axial width of the fan blades. The ring dia. in the projecting region can increase constantly from approx. the middle of the blades.
