Abstract (en)
[origin: WO2007016894A1] In the case of a two-part oil scraper ring (10) for internal combustion engines, having a U-shaped expanding-spring ring (1), which is provided with axial indentations (2), for forming radially outwardly aligned resilient limbs (3, 4) which are connected to one another by means of radially inwardly situated webs (5), and having an annular body (7) which is provided with in each case parallel flanks (7a, 7b) and a running face (9), according to the invention, a minimum axial installation height with an improved oil-scraping effect should be obtained in that the flanks (7a, 7b) of the annular body have, in their radially inwardly situated wall region, cut-outs (11) which have a support face (12) for the engagement of the resilient limbs (3, 4) of the expanding-spring ring and are shaped such that the nominal height of the oil scraper ring is determined exclusively by the height of the annular body (7).
