摘要： A control device for an intake valve of an internal combustion engine comprising an adjusting element and a control element. According to the invention, the adjusting element comprises a base body (2) and is displaceably arranged between the control element and the valve. The control element rotates during the operation of the control device. Rotating control element circumferential areas with contours that vary in the circumferential direction are provided as control cams throughout the rotating control element. Force introduction areas KEB (6, 7), which are positioned in a non-uniform manner, and a force transfer area KUB (3) are provided on the base body (2) of the adjusting element. Switching means for the alternately M contacting assignment of the KEB areas (6, 7) are provided on the different control cam areas of the control element The aim of the invention is to enable the largest possible number of different controls for an engine valve. To this end, the invention provides that, (“f”) in a control device of this type, the mutual assignment between the one KUB area (3) and the at least two KEB areas (6,7) can be modified among one inside the adjusting element base body (2) by means of the switching means.

摘要： The aim of the invention is to functionally improve a hydraulic play compensation element for a valve gear of an internal combustion engine. To this end, the play compensation element is characterized by the following features. Both components (4; 6) enclose a pressure chamber (7) between them, which is sealed from the exterior and which has a volume that depends on the relative position of both components (4; 6). A pressure spring (5) that presses both components (4; 6) away from one another is mounted inside the pressure chamber (7). The pressure chamber (7) can be connected to the storage chamber (8) via a spring-loaded one-way valve (10) through which media can flow exclusively into the pressure space. An additional controllable stop valve (11) is provided in the connection of the pressure chamber (7) to the storage chamber (8). A throttling channel (17), which serves as a bypass to the one-way valve (10), is provided between the pressure chamber (7) and the controllable stop valve (11). The throttling channel (17) is connected to a reversibly size-changing buffer chamber (22).
摘要翻译：本发明的目的是在功能上改进用于内燃机的阀齿轮的液压游隙补偿元件。为此，播放补偿元件的特征在于以下特征。两个部件（4; 6）都包围在它们之间的压力室（7），该压力室（7）从外部密封并具有取决于两个部件（4; 6）的相对位置的体积。将两个部件（4; 6）彼此远离的压力弹簧（5）安装在压力室（7）内。压力室（7）可以通过弹簧加载的单向阀（10）连接到储存室（8），通过该弹簧加载的单向阀（10），介质可以通过该单元阀专门流入压力空间。在压力室（7）与储存室（8）的连接处设置有一个可控制的止回阀（11）。在压力室（7）和可控截止阀（11）之间设有用作到单向阀（10）的旁路的节流通道（17）。节流通道（17）连接到可逆尺寸改变的缓冲室（22）。

摘要： The invention relates to a camshaft made of cast steel having an inner cavity with a cylindrical inner shape, especially a profiled cylindrical inner shape produced rationally according to a lost-foam casting method known per se. A steel camshaft thus produced exhibits a long service life and can withstand extremely high hertzian surface pressures on its bearing surfaces without any damages.
