1·The phosphorus plays a similar, though lesser, role in protecting the engine’s valve gear.

磷尽管发挥的作用较小但也有类似功效，都是为了保护发电机的阀动装置。

2·Longer mainly for underground pipes or difficult to close the valve valve gear for extended use.

用途use加长机构主要适用于地下管道阀门或不易接近的阀门用于加长传动装置使用。

3·The cylinder head carries the valves, valve springs and the rockers on the rocker shaft, this part of the valve gear being worked by push-rods.

缸盖上装有气门、气门弹簧和摇臂轴上的摇臂，推杆推动这部分气门传动机构工作。

4·Valve gear is regarded as stiffness in the traditional design and its elastic deformation in motion is neglected. This method is called static design.

配气凸轮传统的设计方法是把配气机构看成绝对刚体，不考虑它在运动时的弹性变形，这种设计也称为静态设计。
