Abstract

A turbine housing of an exhaust gas turbocharger, includes an outer housing in which an inner housing with a tubular nozzle and an outlet duct for connection to an exhaust gas system is arranged. The outlet duct is coupled with the tubular nozzle for movement relative to the nozzle via a seal ring. The seal ring is inwardly everted and pushed onto the nozzle and embraced by an inner-housing support ring, so that a fluid tight fit on the inner housing nozzle is ensured. The seal ring is further pushed onto the outlet duct and there also coupled onto the outlet duct with an outlet duct support ring in a fluid tight manner so that an especially durable connection is created. Both support rings are additionally coupled in a materially bonded manner with the seal ring and the outlet duct nozzle or with the inner housing.
