The downward - moving side of the rocker arm pushes on the valve stem to open the valve 摇臂向下移动的那一边推动气门杆以打开气门。
In a gas outfit of an automobile , the rocker arm insert and the valve rod form frictional mates that move back and forth , so their working conditions are complicated and bad 汽车发动机配气机构中的摇臂与气门杆构成往复运动的摩擦副,服役条件复杂而恶劣。
Abstract : the mechanical structure of washboard valve leveler is introduced , the alignment mechanics of curving bar and hemilateral pan of the valve is analyzed , the mechanical , the shape of washboard and the effect of alignment quality and efficiency cause by shrink - adaption range of the valve between two washboard are discussed 文摘:介绍了搓板式气门校正机的机械结构,分析了气门杆部弯曲校直和盘部偏歪校正的机理,讨论了机器结构,托板形状和气门在两搓板间的过盈配合量对校正质量和效率的影响。
