ABSTRACT:
The invention relates to bearing support of a throttle valve shaft in the housing of an exhaust gas line in which the shaft is rotatably supported on both sides in a bearing sleeve element constructed cup-shaped. The cups themselves are retained by spring force against the housing extending correspondingly conically within these areas. In order to keep small the actuating forces necessary for the rotation of the throttle valve shaft, each bearing sleeve element is retained by itself against the housing by means of a spring supported at the housing and the securing of the shaft against any axial displacement takes place by a separate axial bearing.
