Abstract
The aim of the invention is to produce a cost-effective oil scraper ring (1) from segments which respectively consist of a metallic retaining ring segment (2) and a plastic insertion ring segment (4) which is positioned in the retaining ring segment in a non-positive manner with play. The non-positive connection is carried out, for example, by means of recesses (24) located in the extension of the bottom of grooves (22) provided in the respective retaining ring segments, and by means of lateral bulges (44) on the insertion ring segments (4). In this way, a tongue-and-groove joint is produced between the two ring segments. The insertion ring segments (4) comprise a plurality of relief wells (49) located between two parallel scraper lamellae (41), said relief wells communicating with oil relief wells (29) in the retaining ring segments (2). Compared to solutions using only plastic and solutions using metallic oil scraper lamellae, the inventive solution is more cost-effective, reducing the wear on the piston rods and thus the oil consumption.
