Abstract

Es wird Radialgebläse mit einem topfartigen Laufrad (10) vorgeschlagen, das an seinem Umfang mit einem Schaufelkranz (15) versehen ist. Ein das Laufrad (10) aufnehmendes Gehäuse (11, 11') erweitert sich ausgehend von einem teilkreisartig gekrümmten, direkt entlang des Schaufelkranzes (15) verlaufenden Umfangswandbereich (19) schneckenartig in Drehrichtung des Laufrads (10) radial zu einem Auslaß (21) und besitzt zwei die axialen Stirnseiten des Laufrads (10) abdeckende Seitenwandungen (23, 24). Eine an einer der Seitenwandungen (24) angeordnete Trennwand (26) greift in das topfartige Laufrad (10) ein und unterteilt dessen Innenraum in einen ersten und einen zweiten Saugraum. Dem ersten Saugraum ist eine Ansaugöffnung (28) zugeordnet, und der zweite Saugraum ist dem direkt entlang des Schaufelkranzes (15) verlaufenden Umfangswandbereich (19) zugewandt. Der direkt entlang des Schaufelkranzes (15) verlaufende Umfangswandbereich (19; 39) ist zur Verhinderung einer Luftströmung zwischen ihm und dem Laufrad (10) mit labyrinthdichtungsartigen Erhöhungen und/oder Vertiefungen (20) versehen.
