摘要： A lash adjuster in a valve actuator includes a lifter body having an end plate having its top surface in contact with a cam and formed with a threaded hole in its bottom surface. An adjuster screw is inserted in the threaded hole with its external thread in engagement with the internal thread of the threaded hole. An elastic member is mounted in the threaded hole over the adjuster screw to bias the adjuster screw axially downward. Both of the threads have a sawtooth-shaped section with its pressure flank having a greater flank angle than its clearance flank. One of the pressure flanks is formed with a satin-finished rugged surface which is covered by a hard film which is non-reactive with a low-friction oil. With this arrangement, even after the threads have become worn, the friction coefficient between the thread surfaces is kept substantially constant.
