摘要： A sealed-type automatic tensioner has a body assembly composed of upper and lower tubular bodies held in threaded engagement with each other, a tubular plunger slidably disposed in the body assembly, a piston slidably disposed in the tubular plunger and having a portion extending slidably through a hole in a top wall of the upper tubular body. The lower tubular body and the tubular plunger jointly define a larger-diameter hydraulic chamber, and the tubular plunger and the piston jointly define a smaller-diameter hydraulic chamber. A bottom wall of the tubular plunger has an aperture through which the larger- and smaller-diameter chambers communicate with each other. A compression coil spring is disposed in the first tubular body and acts between the top wall of the upper tubular body and the tubular plunger for normally urging the tubular plunger to move into the larger-diameter chamber.
