Abstract
A piston ring for sealing gas flow past a sliding cylinder is provided at the interface of the turbine and bearing housings, and is axially close to the turbine inlet. A V-band or similar connection joins the turbine and bearing housings but it is axially further away from the turbine inlet. The piston ring is provided with a spacer element between it and the bearing housing that is at least partially thermally decoupled from the bearing housing.
