Throttle valve device for internal combustion engine, has adjusting device directly fastened to housing in heat-conductive manner, and housing thermally coupled with channel, where heat conducting in device is supplied over channel

摘要

The device has a housing surrounding an exhaust gas conductive channel (3) streamed by a hot medium. A throttle valve (2) controls the channel, and a throttle valve shaft (19) fastens the valve and pivots the valve in a borehole of the housing. The valve shaft is firmly connected with a drive shaft (9) of an adjusting device (1) by microencapsulation. The adjusting device is directly fastened to the housing in a heat-conductive manner, and the housing is thermally coupled with the channel that streams a refrigerant, where a heat conducting in the device is supplied over the channel.
