This patent was filed a long time ago but at that time it was technically very interesting, because it allowed to regulate the opening and closing of engine valves efficiently even at extremely high engine speeds, and this while having the valves axes placed far more freely than a conventional system. The principle is simple: a camshaft rotating in the center of the system pushes the cylinders up, thus pushing the levers eventually acting on the valves. When the camshaft is in its low position, the spring forces the valve to close, thereby pushing the lever back in its normal position and thus making the cylinder go down. |
