Title: (EN) Oil-control ring for an internal combustion engine
(ZH) 用于内燃机的控油环
Abstract: front page image
(EN) An oil-control ring for an internal combustion engine, to be mounted between the sidewalls of a respective groove (10) of a piston (P) and comprising two ring segments (20) and an annular expander (30) disposed between the two ring segments (20) and presenting a support body (31) defining a seating plane for each ring segment (20) , said ring further comprising: at least one expander portion (40) axially projecting from the support body (31) of the expander (30) , beyond at least one of the seating planes of a ring segment (20); and at least one superficial irregularity (50) provided in at least one of the ring segments (20) and which is dimensioned to be contained in the thickness of the respective ring segment (20) and to interfere with at least one expander portion (40), in order to rotatively lock said ring segment (20) in relation to the expander (30) .
(ZH)

本发明公开一种用于内燃机的控油环,所述控油环安装在活塞(P)的相应槽(10)的侧壁之间,并且所述控油环包括:两个环段(20);以及环形胀环(30),其布置在两个环段(20)之间,胀环(30)具有为每个环段(20)限定支承平面的支撑体(31),所述控油环还包括:至少一个胀环部分(40),其从胀环(30)的支撑体(31)沿轴向凸出,超出环段(20)的至少一个支承平面;以及至少一个表面不规则部(50),其设置在至少一个环段(20)中,并且具有这样的尺寸,即:使其包含在相应环段(20)的厚度内,并与至少一个胀环部分(40)干涉,以便相对于胀环(30)旋转锁定环段(20)。
