Desmodromic system

Since the start of the invention of the four-stroke internal combustion engine an attempt to reduce the weight of the motor is possible, in proportion to the power, because this is necessary especially for sports and racing engines. One of the possibilities to increase the specific power is higher revving . It is the distribution, which limits the number of RPM’s to make a powerful engine. This problem is solved with a desmodromic valve control, which is known by many. All existing Desmodromic systems are complex and require a very high precision in production, and are therefore not used. The subject of the invention are, the cams 13, 14 and the camshaft 4 enclosing bearing 11. Cam 14 of bearing 11 is a cam which opens the valve 9 through the lower cam follower 3. A second cam 13 closes valve 9 and pulling it with the lower closure 12 caliper portion, pin 8, top caliper portion 7 and the valve pin 10 upwards towards the valve seat in the cylinder head. The drawings show approximately the shape of a part of the desmodromic distribution. Such a desmodromic system takes a very small place, both in terms of height, width and depth. It can reach high speeds without the risk of failure of the distribution. For engines that do not require high speed a high lift of the valves, in combination with a small valve overlap, can be achieved. It can be made with a substantially higher acceleration and deceleration of the valve without any consequences like the wear of the valveguides and valve seats because of the force of the valve springs. The production is simple. The cams can be carried out by conventional methods, and the second cam is produced by inverted copying of the first cam. The patent subject Desmodromic distribution , in which the double cams [13 , 14], mounted on their shaft [ 4] briefly at the lower [11 ] and the cam followers [3 ] are associated with valve lifters [2 ], which are operated by the double cams [ 13, 14 ]. 1 sheet drawings
