Abstract
The present invention relates to an oil sealing ring, especially that used in piston of internal combustion engine or compressor. This oil sealing ring comprises a base ring (2) with a split. An elastic ring (3) is provided in the inner circumference surface of the base ring. A radially outward annular flange (18) is provided in the outer circumference surface of the base ring. An axially upward annular projecting part (19) is provided in the area beyond the outer circumference surface of the projecting part (19). The splits of said disc ring (1) and said base ring (2) are respectively staggered from each other. This oil sealing ring can effectively prevent the leakage of the oil and the gas.
Claims15
