Abstract
The present invention relates to a blowing device, in particular for use in a respiration device for delivering a respiration gas. The blowing device according to the invention includes an impeller which is driven by way of a drive device and which delivers a respiration gas to an outflow passage. On the way into that outflow passage the gas being delivered flows over a flow breakaway step which together with a spirally enlarging peripheral wall deflects the gas as it flows immediately out of the radial impeller. The invention also relates to a CPAP-apparatus fitted with such a blowing device.
