The invention relates to a multi-part oil scraper ring for pistons of internal combustion engines. Said ring comprises two lamellae consisting of a steel strip and having parallel flanks and an expanding spring that is located between the lamellae, the interspaced spring elements of said spring pressing both axially against respective flanks of an annular groove in the piston and radially against the cylinder wall. The aim of the invention is to effectively prevent the displacement of the ring elements in relation to one another without adversely affecting the flexibility of the ring. To achieve this, at least one of the lamellae (1, 2) has at least one axially prominent deformation (9) on the flank (5) that faces the expanding spring, said deformation engaging in the space (A) between the spring elements (4). |
