ング。 In a combination oil ring consisting of one side rail 10 fitted in an oil ring groove 22 of a piston 20 and a spacer expander 12 supporting it, an auxiliary ring 15 is disposed inside and below the spacer expander, The center of gravity B of the auxiliary ring is the fulcrum A of the side rail rocking, where the inner end of the side rail contacts the upper inner surface of the oil ring groove.
The moment of inertia of the auxiliary ring around the fulcrum in the direction of pushing down the side rail is equal to the sum of the moments of inertia of the side rail and the spacer expander in the direction of lifting the side rail. A combination oil ring characterized by being larger than that.
