Abstract

A high-power radial flow ventilator comprises a bladed impeller 21 which is shielded at the side adjacent an inlet nozzle 11 by a shroud ring 10. The ring 10 overlaps the inlet nozzle 11 with an annular clearance "S". The curve which determines the shape of the ring and which is arcuate, parabolic or hyperbolic, is described with a radius R, or with several radii, the ratio of which to the smallest diameter (do) of the ring (inlet diameter), is 0.21- 0.30, and is preferably 0.225-0.280 to 1. <IMAGE>
