Abstract

In order to guarantee a high degree of efficiency, even with different speeds, a lateral channel (2, 2A, 2B) with an elliptical cross-sectional surface is provided, which tapers from an aspiration side through to a pressure side. Here, the elliptical cross-sectional geometry is formed by a supporting ring (18) of an impeller (12) and by an inside wall area (28) of a casing (6, 8). The supporting ring (18) and the inside wall area (28) enclose the lateral channel (2) almost fully, the elliptically curved wall areas passing homogeneously into each other.
