Abstract

PURPOSE: To reduce the frictional loss of oil film by half with reduced amount of oil by providing the oil film between a seal ring and a shaft only on the vacuum side for sealing the shaft by the oil supplied in an atmospheric pressure.
CONSTITUTION: The oil in an oil tank 11 is naturally dropped and supplied to a seal ring 3. The gap between the seal ring 3 and a shaft 1 is provided only on the side of a vacuum chamber 4. The gap part is filled with the oil supplied to the seal ring 3. Since the pressure of the oil is mostly based on an atmospheric one, almost all oil is introduced into a cacuum-side oil drainage chamber 4. This introduced oil is collected by a fixed method together with the oil issued to the atmospheric side, and returned to the oil tank 11 by an oil pump.
