摘要：A clearance-sensing slack adjuster operated by an air cylinder brake applicationstroke has two linearly disposed spindles axially aligned. A screw threaded adjusterspindle is rotatably mounted in a rotationally immovable adjustment nut with a clearancespace separating the spindle end in a normal position from the end of the other pushspindle member which is rotatable within the brake push rod, so that the two spindlesmembers can axially engage each other and rotate in a direction selected by one wayclutch arrangements to adjust slack on the return stroke. Means is provided to preventadjustment during the elasticity part of the release stroke. The screw threads of the twospindles have the same pitch but different diameters so that only the adjuster nut is non-self-locking.
