    • A mechanical valve tappet for timing the valves of an internal combustion engine comprising a cup-shaped housing (1), consisting of a hollow cylindrical wall (2) closed at one end by a bottom (3) which is exteriorly contacted by a control cam (6), while on the inner surface of the bottom (3), there is arranged an elevation (4) which cooperates with the end of a valve stem of a gas exchange valve (5) and while the other dimensions of the valve tappet remain unchanged, the elevation is made in each case with a different axial extent whereby the valve clearance can be adjusted without the adjusting elements hitherto required by the prior art by inserting the entire cup-shaped housing (1) having the appropriate elevation (4) into the cylinder head.
    • 一种用于对包括杯状壳体(1)进行定时的内燃机的阀的机械阀挺杆,该杯形壳体由在一端由底部(3)封闭的中空圆柱形壁(2)组成,该底部由控制凸轮 (6),而在底部(3)的内表面上,设有与气体交换阀(5)的阀杆的端部配合的高度(4),而阀挺杆的另一个尺寸 保持不变,在每种情况下以不同的轴向范围进行升降,由此通过插入具有适当高度(4)的整个杯形壳体(1),可以调节阀间隙,而不需要现有技术所要求的调节元件, 进入气缸盖。

    • What is proposed is a lever-type cam follower (1) made of sheet metal, typically for a valve train of an internal combustion engine, said cam follower (1) comprising two parallel side walls (3a, 3b) connected by a crossbeam (2), an underside (4) of the crossbeam (2) having a support (6) for at least one gas exchange valve on one end (5), said support (6) being limited by guide walls (7a, 7b) extending parallel to the side walls (3a, 3b), wherein the one end (5) of the cam follower (1) is narrower than the rest of the length of the cam follower (1), and at least in the region of said one end (5), the side walls (3a, 3b) have a smaller mean wall thickness (DSM) than over the rest of said length, which wall thickness (DSM) increases at least in said region continuously from ends (8a, 8b) of the side walls (3a, 3b) in the direction of the crossbeam (2), and the thickness (DF) of the guide walls (7a 7b) is smaller than the mean wall thickness (DSM) in the region of the narrow one end (5). Such a cam follower (1) requires only a small design space in the region of the one end (5) and has a particularly favorable mass moment of inertia.
    • 提出的是一种由金属板制成的杠杆式凸轮从动件(1),通常用于内燃机的气门机构,所述凸轮从动件(1)包括通过横梁连接的两个平行的侧壁(3a,3b) 横梁(2)的下侧(4)具有在一端(5)上用于至少一个气体交换阀的支撑件(6),所述支撑件(6)由延伸的导向壁(7a,7b)限制 平行于侧壁(3a,3b),其中凸轮从动件(1)的一端(5)比凸轮从动件(1)的长度的其余部分窄,并且至少在所述一个 端部(5),侧壁(3a,3b)的平均壁厚(DSM)比所述长度的其余部分小,该壁厚(DSM)至少在所述区域中从端部(8a,8b)连续地增加, 的横壁(2)的方向上的侧壁(3a,3b)的厚度(DF)小于导向壁(7a)的厚度(DF) 结束(5)。 这种凸轮从动件(1)在一端(5)的区域中仅需要小的设计空间,并且具有特别有利的质量惯性矩。
