Abstract

Zur Verbesserung des Wirkungsgrades einer Seitenkanal-Saugmaschine wird vorgeschlagen, in den Einlaßbereichen der Seitenkanäle (44) jeweils eine ebene Leitwand (102) vorzusehen, die vom Grund des Seitenkanales bis in die Stirnfläche des Gehäuseteiles (12) reicht, in welchem der Seitenkanal ausgebildet ist. Die Leitwand (102) ist gegenüber einem durch ihre Mitte gehenden Radiusstrahl verkippt, vorzugsweise um etwa 40o.
