[0022] figure 1 with figure 2 The positional relationship between related components in the embodiment of the engine variable valve drive mechanism of the present invention is described. These components are part of the valve drive chain 200 of the engine. The cam roller 235 is rotatably arranged on the roller shaft 231, and the roller shaft 231 is arranged on the component 210. The component 210 can be a rocker arm of an overhead cam engine, or a cam follower of a push rod engine (because people are familiar with engines, some engine parts, such as rocker arms, push rods, cam followers, And valves, etc., not listed here). The roller drive mechanism 100 is provided in the component 210. The roller drive mechanism 100 here includes a spring 156 and a piston 164. One side of the piston 164 (the left side in the figure) receives the force of the spring 156, and the other side of the piston 164 (the right side in the figure) receives the force of the fluid (such as engine oil).
