ABSTRACT:
An oil ring assembly comprising a pair of split rails and a piston ring spacer/expander on which said rails are mounted. Each rail is provided with a radially inwardly extending protrusion that lies substantially entirely within the thickness of the rail. The protrusion extends into and engages the spacer expander to limit the circumferential movement of the rail relative to the spacer/expander.
