Abstract: The invention relates to a radial turbine. The radial turbine comprises: —a turbine housing having a radial gas inflow channel; —a nozzle ring, which is disposed in the radial gas inflow channel; and —an annular cleaning device for cleaning the nozzle ring. The annular cleaning device is connected to a cleaning-agent feed by means of an axially insertion-connectable supply line such that, after or during the demounting of the nozzle ring, the annular cleaning device can be removed from the turbine housing in the axial direction. The invention also relates to a method for mounting a cleaning device for cleaning a nozzle ring of a radial turbine and to a method for demounting the cleaning device.

Abstract: An exhaust turbocharger comprises a turbine having a turbine wheel and a compressor having a compressor wheel. The turbine wheel and the compressor wheel are connected by a shaft rotatably mounted in a bearing housing. A means for axially securing the shaft and the turbine wheel connected thereto is provided between the compressor wheel and the turbine wheel. The means limits an axial movement of the shaft and of the turbine wheel connected thereto in the direction of the turbine in the event of the compressor wheel bursting. The means comprises a component which is screwed onto the shaft during mounting and is fixed in the axial direction in the housing.
