Abstract

The long-life piston ring is cut so as to form one or more horizontal lips (8) extending in the lengthwise direction, parallel on the top and bottom faces. This forms grooves extending in all directions for the assage of lubricant etc. There can be an expansion spring fitted between the vertical faces where the lips are formed. Any wear taking place on the outer ring surface thus does not increase the gap between the ends.
