Abstract (en)
[origin: EP0602558A1] In an apparatus for transporting a gaseous medium with a radial-flow blower (1), the flow channel (8) is widened in the region (14) of the outlet openings (15) of the impeller (2), designed as a paddle wheel, both in the axial direction and in the radial direction from the outlet openings (15) in the direction of the axis of rotation (16) of the impeller (2). This widening (18) has the effect of returning part of the expelled medium to the impeller (2). An increase in the energy potential of the transported medium occurs. At the same time, noise reduction is achieved and the occurrence of periodic pressure fluctuations is avoided. <IMAGE>
