    • PURPOSE: The cup is hard ended in a heat treatment process and the inner part is unhardened in order to eliminate the processing of the cup. CONSTITUTION: A valve tappet actuated by the cam of an internal combustion engine is made up iron-metal materials, and comprises of a base(3) which closes the end of the shell(2), an inner part(6), and an oil chamber. On the exterior, the shell(2) has a peripheral groove(4) and, on the interior, it is provided with at least one bead(5,21). Disposed concentrically inside the cup(1) is an inner part(6) of which the casing(9) abuts the bead(5,21). An oil chamber is located between the casing(9) and the shell(2), and makes oil channels, and a hydraulic valve clearance compensating element (10) is guided in an axially movable manner inside the inner part (6).
    • 目的:杯子在热处理过程中硬化,内部未硬化,以消除杯子的加工。 构成:由内燃机的凸轮致动的阀挺杆由铁金属材料制成,并且包括封闭壳体(2)的端部的基部(3),内部部分(6)和 油室。 在外壳上,外壳(2)具有周边槽(4),并且在其内部设置有至少一个胎圈(5,21)。 杯子(1)内同心地配置有内壳(6),外壳(9)抵靠珠子(5,21)。 油室位于壳体(9)和壳体(2)之间,并且形成油通道,并且液压阀间隙补偿元件(10)以可轴向移动的方式被引导到内部部分(6)内。
