Beschreibung
Zusammenfassung:	The disclosed rolling piston type compressor comprises a needle bearing sandwiched between two bearing washers and serving as a thrust bearing for a rotary shaft and a resilient sealing ring of polytetrafluoroethylene press fitted into a space defined by the outer periphery of the needle bearing and the two bearing washers. Alternatively the sealing ring may be formed of cast iron and seal the space with an oil film disposed in a clearance between the ring and one of the bearing washers.
