A turbocharger, includes a turbine for expanding a first medium, the turbine has a turbine housing and a turbine rotor, a compressor for compressing a second medium, having a compressor housing and a compressor rotor that is coupled to the turbine rotor via a shaft. The turbine housing and the compressor housing are each connected to a bearing housing arranged between them, in which the shaft is mounted. In a connecting region between an inflow housing of the turbine housing and the bearing housing a sealing cover is arranged. On a radially inner section of the sealing cover a projection extending in the axial direction is formed, which engages into a groove introduced into the bearing housing forming a radially inner fit and a radially outer fit.
