Patent number: 9341081Abstract: 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, wherein the outlet duct is coupled to the tubular nozzle via a sealing lip for relative movement. The sealing lip is inwardly evertedly pushed onto the nozzle and for positional fixing, a sliding sleeve is further arranged on the nozzle, wherein the sliding sleeve and the nozzle form a gap in which an end of the sealing lip is received. This avoids that the sealing lip lifts of due to pressure differences and thus that gas leaks occur. Further, an end of the sealing lip is arranged so as to be thermally protected.Type: GrantFiled: May 19, 2011Date of Patent: May 17, 2016Assignee: BENTELER AUTOMOBILTECHNIK GMBHInventors: Christian Smatloch, Elmar Grussmann
