Abstract:
A continuous compression ring for a piston reciprocally operable in a combustion cylinder of an IC engine, the piston having a cylindrical outer surface portion extending therearound including a circumferentially extending piston groove therein and an end portion adapted for connection to a connecting rod of the engine, the continuous compression ring comprising:a continuous annular member cooperatively receivable in the circumferentially extending piston groove, the continuous annular member having a generally G-shaped cross-sectional shape including an in-turned end portion which forms a circumferentially extending lip positioned to be located radially outwardly of the cylindrical outer surface portion around the piston when the annular member is cooperatively received in the circumferentially extending piston groove, the circumferentially extending lip being adapted for forming a substantially sealed condition around the piston in cooperation with an oil film on a wall defining the combustion cylinder when the piston is positioned for reciprocal operation therein.
