Abstract

Die Erfindung betrifft einen mehrteiligen Ölabstreifring für Kolben von Verbren­nungsmotoren, mit zwei aus Stahlband bestehenden Lamellen mit parallelen Flanken und einer zwischen den Lamellen angeordneten Spreizfeder, deren beabstandete Federelemente die Lamellen sowohl axial gegen jeweils eine der Flanken einer Ringnut im Kolben als auch radial gegen die Zylinderwand drücken. Erfindungsge­mäss soll eine Relativbewegung der Ringelemente gegeneinander ohne Beeinflus­sung der Ringflexibilität wirksam dadurch verhindert werden, indem mindestens eine der Lamellen (1, 2) auf seiner zur Spreizfeder gerichteten Flanke (5) mindestens eine axiale erhabene Verformung (9) aufweist, die in den zwischen den Federelementen (4) bestehenden Abstand (A) eingreift.
