摘要： A turbo-machine arrangement having a compressor section comprising a compressor shaft, an electric machine having a shaft, the compressor shaft is coaxial to the shaft. The compressor shaft is coupled to the electric machine shaft. The electric machine and compressor section are arranged in a common housing and mounted via bearings. The housing having a supply line via which uncompressed working medium is supplied, a discharge line, via which compressed working medium is discharged, and an ejector, supplied via a first connection with working medium at a first pressure level for drawing in working medium at a lower second pressure level via a second connection. A mixture formed in the ejector is supplied to the electric machine and/or another assembly to be cooled via a third connection.
