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 for producing a defined volumetric flow, such as is needed in particular for devices for ventilation therapy. This is achieved by means of a new type of shape of the blade chambers (24) in the impeller (12) and the blade chamber walls (29), which separate the blade chambers and become thicker toward the impeller circumference, supported by a high-speed drive, a large number of blade chambers (24), and a small impeller diameter.
