SMALL, LOW-NOISE SIDE CHANNEL COMPRESSOR, IN PARTICULAR FOR DEVICES IN VENTILATION THERAPY

摘要

The invention relates to a small, low-noise side channel compressor forproducing a defined volumetric flow, such as is needed in particular fordevices for ventilation therapy. This is achieved by means of a new typeof shape of the blade chambers (24) in the impeller (12) and the bladechamber walls (29), which separate the blade chambers and becomethicker toward the circumference of the impeller, supported by a high-speeddrive and a large number of blade chambers (24) at a smallimpeller diameter.
