Abstract:
An elongated securing device or anti-rotation bridge as a mounting aid for a valve drive for an internal combustion engine, the device or bridge having a plurality of first and second receptacle spaces with each space for receiving a valve tappet and the receptacle spaces being arranged at intervals one after the other;a respective first valve tappet being located in each of the first receptacle spaces and a respective second valve tappet being located in each of the second receptacle spaces, wherein the valve tappets can be displaced longitudinally in their respective receptacle spaces; each of the valve tappets being secured in its respective receptacle space against rotation of the valve tappet in the receptacle space with respect to the device, wherein each tappet has an outer surface including two parallel planar keying faces formed on the outer surface, and the receptacle space for the tappet has corresponding inner surfaces defining the receptacle space and shaped and positioned for bearing against the keying faces of the respective tappet; wherein the first receptacle spaces have a relatively smaller interval dimension between the respective inner surfaces, and the keying faces of the first valve tappets have a corresponding interval dimension for receiving the first keying faces against the first inner surfaces of the first valve tappets and wherein the second receptacle spaces have a relatively larger interval dimension between the respective inner surfaces, and the keying faces of the second valve tappets have a corresponding interval dimension for receiving the second keying faces against the second inner surfaces of the second valve tappets.
