    • A slack adjuster for narrow gauge rail cars including a housing having a body with a first clevis joint, a coupling secured to the body, and a guide tube secured to the body coupling. A lever is pivotally coupled to the housing for moving an actuator coupled to a clutch. The clutch is engaged with the external threads of a rod and moveable between a first captured position, a second position where the clutch is free to rotate, and a second captured position to selectively control movement of the rod. Movement of the lever withdraws the actuator so that the clutch releases and can spin, allowing the threaded rod to translate from the retracted to extended positions. Opposing forces applied to a ram causes the clutch to move to the second captured position, thereby preventing rotation of the clutch and preventing the threaded rod from retracting further into the housing.
    • 一种用于窄轨道车厢的松弛调节器,包括具有主体的壳体,壳体具有第一U形夹接头,固定到主体的联接器和固定到主体联接器的引导管。 杠杆枢转地联接到壳体,用于移动联接到离合器的致动器。 离合器与杆的外螺纹接合并可在第一捕获位置,离合器自由旋转的第二位置和第二捕获位置之间移动,以选择性地控制杆的运动。 杠杆的移动使执行机构退回,使得离合器释放并且可以旋转,从而允许螺杆从缩回位置到伸展位置平移。 施加在压头上的相对力导致离合器移动到第二捕获位置,从而防止离合器旋转并防止螺杆进一步收回到壳体中。
