Beschreibung
Zusammenfassung:	An oil seal construction for rotary engines includes an oil scraper ring disposed in an oil seal groove of the rotor. The ring extends into sealing contact with adjacent surfaces of the rotor housing wall. An annular Belleville type spring is disposed in the groove for urging the ring against the wall. This spring possesses openings for decreasing stiffness with a cover of elastic material covering the opening while extending over surfaces of the spring abutting the grooved surfaces and scraper ring.
