OIL SEAL CONSTRUCTION
CHU011011910S06
• To prevent the oil that is supplied to the inner rotor for cooling and for lubrication of the bearings from leaking
into the combustion chambers from the side surfaces, two oil seals have been added to each side of the rotor.
• The tapered lips press against the housing friction surface to perform oil sweeping and have employed hard-
chrome plating for improved wear resistance.
• The addition of oil seal springs between the oil seals and the rotor maintain a oil seal against the side housing
friction surface. Colored marks for identification of the spring have been added on the oil seal spring.
