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.

Abstract: An improved split thrust washer assembly for a vehicle transmission speed shaft. The assembly includes a pair of semi-circular washer segments held in a speed shaft circumferential groove by a C-type compression retaining ring. The ring biases each washer segment interior surface into contact with the groove base wall during maximum shaft speeds thereby neutralizing the centrifugal force tending to separate the segments from the groove. The segments have radially extending opposed end faces having a predetermined minimal clearance therebetween thereby insuring that the segments are maintained in contact with the groove. The thrust washer assembly allows a shallower groove to carry the design thrust loads so as to improve shaft fatigue life.
