摘要： A single-piece oil control ring for a piston may include a body having at least one upper portion and at least one lower portion each facing towards a cylinder wall of an internal combustion engine. At least one of the upper portion and the lower portion may respectively define a first surface extending substantially perpendicular to the body and a receding second surface extending from the first surface substantially at an incline. The first surface may protrude towards the cylinder wall in relation to the second surface. The first surface may have a first area of contact with the cylinder wall, and at least 95% of the first area may contact the cylinder wall.
