Abstract

Durch die Erfindung wird ein Lüfterrad einfachen Aufbaus geschaffen, das insbesondere für den Einsatz in Kühlsystemen von Brennkraftmaschinen vorgesehen ist und dort durch Umkehrung der Förderrichtung auch als Reinigungsgebläse zum Freiblasen des Kühlers und/oder entsprechender Lufteintrittsöffnungen nutzbar ist.

Figure 00000001
The invention provides a fan wheel of simple construction, which is provided in particular for use in cooling systems of internal combustion engines and can also be used there by reversing the conveying direction as a cleaning fan for blowing out the cooler and / or corresponding air inlet openings.
