ABSTRACT:
A seal assembly (54) for closing a cavity (55) between a rotor (24), a bearing retainer (38) and a crankshaft (80) to retain a fluid therein for lubricating bearings (48, 50, 90) associated with the crankshaft (80). Seal assembly (54) has a disc (72) with a first resilient member (56) that engages the rotor surface (44) and a second eccentrically positioned resilient member (62), that engages surface (65) on bearing retainer (38). Disc (72) which is attached to crankshaft (80) rotates with ring gear (36) around pinion (32) to maintain a sealed cavity (55) even though the first and second resilient members (56 and 62) rotate on their respectively sealing surfaces (44 and 65) with different revolutions per minute.
