- exhaust valve lifter 排气阀挺杆
- The cam has a high point, or lobe; every time the cam rotates, the lobe comes around under the valve lifter and move it upward. 凸轮有一个最高点,即凸角,每一次,凸轮旋转,凸角旋转到挺杆的下部,使其向上移动。
- On most engines, this mechanism, called the valve train, includes a cam on the camshaft, a valve lifter, a push rod, and a rocker arm. 在大多数发动机中,这套装置叫做气门机构。这套装置中包括凸轮轴上的一个凸轮、一个气门挺杆、一个气门推杆和一个摇臂。
- When the piston nears the top of this stroke, the inlet valve is opened and the exhaust valve closed. 随着曲轴转动，复又向上带动活塞，同时废气经由气缸头盖上的排气阀排出。
- The New Way of Calculation on Valve Lift of Cam Mechanism 凸轮机构气门升程的新算法
