Abstract

Die Erfindung betrifft ein Radialgebläserad, mit einem Nabenkörper und einem Umfangsrand, einer Vorderseite und einer Rückseite, sich von dem Nabenkörper bis zum Umfangsrand im wesentlichen radial erstreckenden Schaufeln, einem Ansaugbereich und einem Abströmbereich, mit einer ringförmigen Deckscheibe auf der Vorderseite, in der eine Ansaugöffnung ausgebildet ist und mit einer rückseitigen Tragscheibe, wobei_die ringförmige Deckscheibe eine Breite RD aufweist, die vom Rand der Ansaugöffnung gemessen, kleiner ist als der Abstand Rand- Ansaugöffnung bis Austrittsöffnung -Umfangsrand.

Figure imgaf001
The invention relates to a radial impeller, having a hub body and a peripheral edge, a front and a back, extending from the hub body to the peripheral edge substantially radially extending blades, a suction and a discharge area, with an annular cover plate on the front side, in which a suction port is formed and with a rear support plate, wherein_ the annular cover plate has a width R D , which is measured from the edge of the suction port, smaller than the distance between the edge suction port to exit port peripheral edge.
