Charging device
A charging device may include a turbine housing and a bearing housing. The bearing housing may have a bearing arrangement for a shaft carrying a turbine wheel and a compressor wheel. A gasket may be arranged by metal-to-metal connection between a radially orientated flat surface of the turbine housing and a radially orientated flat surface of the bearing housing. The gasket may be resilient.
1. A charging device comprising:
a turbine housing,
a bearing housing having a bearing arrangement for a shaft carrying a turbine wheel and a compressor wheel, a gasket arranged by metal-to-metal connection between a radially orientated flat surface of the turbine housing and a radially orientated flat surface of the bearing housing, wherein the gasket is resilient; and
a guide vane cage disposed between the turbine housing and the bearing housing by a floating contact connection, wherein the guide vane cage forms a radially extending side wall of a nozzle.
2. The charging device according to claim 1 , wherein the gasket is a disc spring.
3. The charging device according to claim 1 , wherein the gasket is at least one of a heat-resistant steel material and a nickel-based alloy.
