    • A sealing apparatus for use in sealing a clearance between a cylinder (38) and a piston (50) without using a lubricating oil. An annular groove (66) is formed in the outer circumferential surface of the piston (50). First and second seal members (68, 70) formed out of a resin material are fitted annularly in an axially piled two-stage in this annular groove (66). A third seal member (72) is fitted annularly on the inner side of these first and second seal members (68, 70). On the inner side of the third seal member (72), a non-endless expander ring (74) adapted to press the first and second seal members (68, 70) against the inner circumferential surface of the cylinder (38) via the third seal member (72) is provided. The first, second and thrid seal members (68, 70, 72) are fitted in the groove (66) so that the clearances between both ends of these seal members are staggered from one another in the circumferential directions thereof and not aligned with one another, and, therefore, the three seal members (68, 70, 72) are arranged in the groove (66) as if a single endless ring were fitted therein.

    • A power cylinder assembly for an internal combustion engine is provided. The power cylinder assembly includes a cylinder wall having a channel formed therein and a piston body with a skirt. A piston ring is seated within the channel of the cylinder wall and is sealed against the skirt of the piston body. Specifically, the piston ring has a ring body with an inner face that presents two radially inwardly extending ridges spaced axially from one another by a valley region, and the outer face presents a groove which receives a spring to bias the ridges into sliding engagement with the outer surface of the skirt of the piston body. The ring body also has at least one oil drainage port which extends radially between the valley region of the inner surface and the groove of the outer face for conveying oil from between the ridges into the groove.

    • A sealing system for the compression ring (5) of a piston (1) of an internal combustion engine comprises placing an elastomeric material seal ring (15) behind the compression ring (5) to provide sealing to improve compression ratio and prevent loss of oil. The seal ring may be an O-ring of a neoprene/silicon blend elastomeric material of circular, U-shaped, oval, square, rectangular or trapezoidal shape, and may be hollow or solid. The seal ring may have a cross-sectional diameter of from 50 % to 100 % of the thickness of the compression ring (5) behind which it fits.
