    • A valve clearance adjustment mechanism for use in small internal combustion engines such as, for example, side valve engines and overhead valve engines, which generally include intake and exhaust valves actuated by lifters pivotally mounted within the engine housing, which in turn are actuated by cam lobes driven in timed rotation with the crank shaft. An adjustment member is provided for mounting each lifter to a shaft, wherein the adjustment member is eccentric relative to the shaft, such that rotation of the adjustment member modifies the position of the lifter and in turn modifies the valve clearance between the lifter and the valve. After the valve clearance has been properly set, the adjustment member is fixed in position.
    • 用于小型内燃机(例如侧阀发动机和顶置阀发动机)的阀间隙调节机构,其通常包括由枢转地安装在发动机壳体内的升降器致动的进气门和排气门,该升降器又由凸轮 带曲柄轴定时转动的叶片。 提供了一种用于将每个升降器安装到轴上的调节构件,其中调节构件相对于轴是偏心的,使得调节构件的旋转改变升降器的位置,并且进而改变升降器和阀之间的间隙 。 阀门间隙正确设定后,调整部件固定就位。
