摘要： A control system for changing permanently and stepless valve timing in engines with internal combustion.The system is based on the fact that camshaft turns two times slower then the crankshaft.The system contains a double gear that is pivoting around the camshaft gear.The pinion gear is coupled with the camshaft gear.The driver gear is connected to the crankshaft gear through satellite gears, chain or belt. Pivoting the system around the camshaft gear can change valve timing in large limits.There are two different cassettes, the first one (FIG. 3, FIG. 3b and FIG. 4) is for pushrod engines and helps eliminate the inertia of the moving parts. Its movement is controlled by the accelerator pedal.The second cassette (FIG. 5 and FIG. 6) is designed for OHC (over head camshaft) engines and it must pivot around the camshafts moved by actuators under the control of the car computer.

摘要翻译： 一种用于在具有内燃机的发动机中改变永久和无级气门正时的控制系统。 该系统基于凸轮轴比曲轴慢两倍的事实。 该系统包含围绕凸轮轴齿轮枢转的双齿轮。 小齿轮与凸轮轴齿轮联接。 司机齿轮通过卫星齿轮，链条或皮带连接到曲轴齿轮。 围绕凸轮轴齿轮旋转系统可以在极限范围内改变气门正时。 存在两个不同的盒，第一个（图3，图3b和图4）用于推杆发动机并且有助于消除运动部件的惯性。 其运动由加速踏板控制。 第二盒（图5和图6）被设计用于OHC（过头凸轮轴）发动机，并且它必须围绕在汽车计算机的控制下由致动器移动的凸轮轴枢转。
