Reduced friction oil control piston rings

A liquid lubricant seal for internal combustion engines, gas pumps and gas compressors for use in a piston;

• wherein the seal is diametrically expandable multiple component ring assembly, and comprises an outside diameter, an inside diameter, and upper and lower faces substantially perpendicular to the piston ring axis;
• the piston has an annular ring groove comprising an upper flank, a lower flank and a bottom, and the piston is reciprocally moveable in a bore;
• the seal ring assembly is disposed in the ring groove such that the outside diameter of the seal assembly is in sliding contact with the cylinder bore surface, the inside diameter is spaced away from the groove bottom, and the seal assembly upper and lower faces are adjacent the upper and lower groove flanks respectively;
• and
• the seal assembly comprising at least one thin annular scraper ring with a first flank surface in sliding contact with an adjacent piston groove flank, an annular spring means applying an outward radial force to the scraper ring distributed around the circumference of the inner ring diameter, and at least one support ring providing substantially uninterrupted axial contact with the second scraper ring flank surface such that the first scraper ring is supported in the axial direction and the first flank surface is maintained in sliding contact with the adjacent piston groove flank.
