Abstract
An exhaust-gas turbocharger for an internal-combustion engine is described, its turbine having a double flow housing with two channels for supplying the exhaust gases to the turbine wheel, of which on channel can be closed off as a function of a variable operating parameter by means of a sliding sleeve which is mounted in the housing so as to be axially displaceable by means of a control device. To ensure a clearly defined relationship between the adjustment of the sliding sleeve and the input variables and to create a heat-resistant control device, the sliding sleeve is connected to an axially fixed and circumferentially rotable driving ring via a positive sliding fit driving the sliding sleeve in the circumferential direction, a slot pin fixed to the housing engaging into an oblique helical groove in the sliding sleeve, and a shaft engaging on the driving ring via a positive connection and being guided radially out of the housing via a bearing in the latter.
