Beschreibung
Zusammenfassung:	Electrical compressors for internal combustion engines, comprising a compressor housing (10) having a spiral channel (12), an impeller (16), which is arranged in the compressor housing (10), an electric motor (20), an electric-motor housing (24), in which the electric motor (20) is arranged and to which the compressor housing (10) is fastened, a drive shaft (18), which can be driven by the electric motor (20) and which is supported by means of a bearing unit (54) in the electric-motor housing (24) and on which the impeller (16) is fastened, and a seal unit, which is arranged axially between the impeller (16) and the bearing unit (54) of the electric motor (20), are known. In order to reliably prevent an ingress of dirt while simultaneously achieving low wear, according to the invention the seal unit has a slide ring seal (76) having at least two corresponding sealing elements (78, 80), the effective sealing surface (77) of which slide ring seal is arranged between the spiral channel (12) and a flow channel (90) with regard to flow, via which flow channel a sealing-gas flow can be sucked in.
