Abstract

The invention has for its object an impeller for cross-flow fans. consisting of two circular end plates with axially extending blades mounted distributingly over the circumference thereof, and of at least one ring- or disc-shaped stiffening element arranged between the two end plates. The stiffening element 1 is provided along its circumference with a number of teeth 2 with thickened ends 3, bent in the direction of rotation of the impeller, with the number of said teeth 2 corresponding to the number of blades, and the internal edges of said teeth being shaped in accordance with the curvature of said blades. <IMAGE>
