Abstract: A turbocharger having a turbine with a turbine rotor, a compressor with a compressor rotor that is coupled to the turbine rotor via a shaft. A bearing housing arranged between the turbine housing and the compressor housing, wherein both the turbine housing and also the compressor housing are connected to the bearing housing, with at least one bearing, via which the shaft is mounted in the bearing housing, wherein the respective bearing includes a bearing bush that is mounted on the bearing housing in a rotationally fixed manner, wherein between the bearing bush and the bearing housing a radially outer lubricating cap and between the bearing bush and the shaft a radially inner lubricating gap is formed, and wherein axial ends of the respective bearing bush, at a radially outer section of the same have a greater axial extent than on a radially inner section of the same.

Abstract: A turbocharger, with a turbine a turbine housing and a turbine rotor, with a compressor with a compressor housing and a compressor rotor that is coupled to the turbine rotor via a shaft, with a bearing housing arranged between the turbine housing and the compressor housing, wherein both the turbine housing and also the compressor housing are connected to the bearing housing, with at least one bearing, via which the shaft is mounted in the bearing housing, wherein the respective bearing comprises a bearing bush arranged in the bearing housing, wherein between the bearing bush and the bearing housing a radially outer lubricating gap and between the bearing bush and the shaft a radially inner lubricating gap are formed, wherein the radially outer lubricating gap and the radially inner lubricating gap are suppliable with lubricating oil emanating from an oil supply main line independently of one another.

Abstract: A radial compressor (10), with a compressor rotor having moving blades and with a compressor housing (11) accommodating an insert piece (12) and a diffuser (13), in which the insert piece (12) delimits a flow duct leading to the moving blades of the rotor and the diffuser (13) a flow duct leading away from the moving blades of the rotor at least in sections, and in which the diffuser (13) is designed as bladeless diffuser and as an integral part of the insert piece (12).
