    摘要： A camshaft has at least two completely machined individual cams fixedly mounted on a shaft in predetermined angular positions. The shaft includes an outside shaft and an inside shaft arranged concentrically in the former, and is to be manufactured in such a way that remachining of the joined camshaft is not necessary. This is by combining the individual cams even before they are mounted on a shaft and joining them to this shaft to form a machining module, such that the individual cams are combined in their mutual arrangement in relation to one another in which the cams are to be mounted on the finished camshaft. The final machining of the cams is performed within this machining nodule. When the cams are completely machined in this way, the cams are joined to the shaft of the camshaft within the machining module. This ensures that the desired mutual arrangement is maintained, i.e., that remachining is not necessary.

    摘要： To hermetically seal a fiber optic light guide (1) in a stripped or de-coated state, I.e. the bare optical fiber (2), in a feedthrough sleeve (5) the bare optical fiber (2) is sealed together with the feedthrough sleeve (5) by composite-glass solder with local heating. To make a permanent hermetic glass seal, the feedthrough sleeve (5) is made from an Invar alloy with very low thermal expansion and the composite-glass solder is low-melting with thermal expansion properties adapted to the alloy. The composite-glass solder is molded into prefabricated half-cylinder-shaped pressed parts (7) in a press/sinter technology process, The stripped optical fiber (2) is inserted between the pressed parts (7) arranged in the feedthrough sleeve (5) and sealed by melting the pressed parts together with each other and with the stripped optical fiber and feedthrough sleeve.

    摘要： The invention relates to a method for the production of glass-coated electric components, wherein the components are, inter alia, passivated by the application of the glass. The lead-free glass used is not affected through purification and processing steps and the electric component is protected from mechanical damaging and other detrimental influences, such as impurities. Further, the method remarkably helps to stabilise the electrical properties of the components. Inter alia, a sufficient acid resistance is achieved and it results in an improvement of the expansion adjustment of the glass.

    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： The present invention relates to a method for grinding of cam profiles on a camshaft (1), having an inner shaft (5) and an outer shaft (4) arranged coaxially one inside the other and mounted to rotate with respect to one another. The camshaft (1) additionally has first and second cams (2, 3) that can rotate with respect to one another over a limited circumferential angle about the camshaft axis (6), the first cams (2) of which are fixedly connected to the inner shaft (5) and the second cams (3) of which are fixedly connected to the outer shaft (4). It is essential to this invention that during and/or after the grinding operation a fluid is forced under pressure into the outer shaft (4), thereby preventing penetration of grinding dust into the interspace (8) between the first cams (2) and the outer shaft (4) or flushing out any grinding dust that has already penetrated.
