摘要: A plastic ring for internal combustion engine pistons. In a preferred embodiment, the ring has an outer diameter lip for engaging the cylinder wall, an inner diameter portion bottomed in the ring groove of the piston, and an axial groove intermediate the outer diameter lip and the inner diameter portion whereby combustion gases will act in the groove to expand the inner diameter into sealing contact with the bottom of the ring groove and expand the outer diameter lip into sealing engagement with the cylinder wall.

摘要: A plastic ring for internal combustion engine pistons. In a preferred embodiment, the ring has a flat outer diameter adapted to engage the inner diameter of a compression piston ring and an inner diameter adapted to engage the backwall of the ring groove. An axial groove slightly spaced from the outer diameter extends into the ring from the top thereof, whereby combustion gases will expand the ring so that it acts as a circumferential expander for the compression ring while preventing blowby of gases through the ring groove. In another modification, the ring is used with its outer diameter acting against the cylinder wall.
