摘要： 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).
摘要翻译：在用于内燃机的两部分油刮环（10）的情况下，具有设置有轴向压痕（2）的U形膨胀弹簧环（1），用于形成径向向外对准的弹性臂 3,4），它们通过径向向内定位的腹板（5）彼此连接，并且具有环形体（7），每个环形体均设有平行的侧面（7a，7b）和行进面（9）根据本发明，应该获得具有改进的刮油效果的最小轴向安装高度，因为环形体的侧面（7a，7b）在其径向向内定位的壁区域中具有切口（11）其具有用于接合膨胀弹簧环的弹性臂（3,4）的支撑面（12），并且成形为使得刮油环的标称高度仅由环形体的高度确定（ 7）。

摘要： In the case of a multi-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 at least two annular lamellae (7, 8) which are provided with in each case parallel flanks (7a, 7b; 8a, 8b) and are stacked via their flanks as stacking planes (SE) to a height (hL) and are arranged between the resilient limbs of the expanding-spring ring in order to define a nominal height of the oil scraper ring, according to the invention, an at least three-part oil scraper ring of a minimum axial installation height and with an improved oil-scraping effect should be obtained in that at least in each case one of the flanks (7a, 7b; 8a, 8b) of the lamellae has, in its radially inwardly situated wall region, a cut-out (11) which has a support face (12) for the engagement of the resilient limbs (3, 4) of the expanding-spring ring and is shaped such that the nominal height of the oil scraper ring is determined exclusively by the stack height (hL) of the lamellae (7, 8).
摘要翻译：在用于内燃机的多部分刮油环（10）的情况下，具有设置有轴向压痕（2）的U形膨胀弹簧圈（1），用于形成径向向外对准的弹性臂 3，4），它们通过径向向内定位的腹板（5）彼此连接，并且具有至少两个环形薄片（7,8），每个环形薄片分别具有平行的侧面（7a，7b; 8a，8b）），并且通过其侧面作为堆叠平面（SE）堆叠到高度（hL），并且布置在膨胀弹簧环的弹性臂之间以便限定刮油环的标称高度，根据本发明，应该获得具有最小轴向安装高度并且具有改进的刮油效果的至少三部分的刮油环，其中至少在每种情况下，薄片的侧翼（7a，7b; 8a，8b）中的一个具有在其径向向内定位的壁区域中具有切口（11），该切口（11）具有支撑面（12）膨胀弹簧环的弹性臂（3,4）的接合被成形为使得刮油环的标称高度仅由片层（7,8）的叠层高度（hL）确定。
