Abstract
The invention relates to a radial compressor () comprising at least one impeller wheel (), which is driven rotatably in a compressor housing () and has a wheel front side () and a wheel rear side (), the wheel front side () being intended to convey a mass flow () by means of a number of blades (), the wheel rear side () of the impeller wheel () having a blading () by means of which a second pressure distribution () is generated on the wheel rear side () of the impeller wheel () during operation of the radial compressor (), which second pressure distribution counteracts a first pressure distribution () on the wheel front side () in order to reduce an axial force that is to be braced in the compressor housing (). In order to functionally improve the radial compressor (), in particular in respect of a use as air supply device in a fuel cell system, the compressor housing () is designed and is combined with the blading () on the wheel rear side () of the impeller wheel () such that, during operation of the radial compressor (), a cooling air mass flow () is conveyed by means of the blading () on the wheel rear side () of the impeller wheel () in addition to the mass flow conveyed by means of the blades () on the wheel front side ().
