Beschreibung
Zusammenfassung:	A sealing device in a transmission with pressure-medium controlled, continuously variable gear ratio for sealing a pressure medium connection between a channel in the transmission housing and a central, axial bore in a pulley shaft rotating in the housing consists of two concentric sleeves with slide surfaces of fine surface finish. One end of the inner sleeve is pressed into the housing channel and is sealed against its wall by means of a sealing ring. The outer sleeve is divided into a shorter portion of large outer diameter with a longer portion of smaller outer diameter. The shorter portion is fitted into the shaft bore and is sealed against the wall of the bore with a sealing ring, there being a space between the wall of the bore and the longer portion.
