摘要： A hermetically sealed autotensioner used for adjusting tension of engine belts comprises a cylinder, a plunger slidably fitted in the cylinder and having a rod projeced from the cylinder, a free piston slidably fitted in the cylinder, and a rod guide fitted in the tip portion of the cylinder so as to slidably support the rod. When a large thrust force acts on the rod, the rod guide serves as a bearing for the rod so that no scuffing or rocking motion occurs between the cylinder and the plunger.

摘要： For preventing very small amplitude vibrations of the rod in a tensioner during high speed movement of a belt to be tensioned by the tensioner, a tube which is connected to a plunger which moves together with the rod is overlapped with a stationary member so as to define an annular clearance therebetween in an operating chamber of the tensioner. By filling an operating fluid in the clearance, shear strain is generated upon high speed movement of the plunger, which resists movement of the plunger.

摘要： An automatic tensioner for adjusting the tension in a timing belt, V belt, or the like has a locking mechanism. The tensioner has a plunger always biased toward a large oil chamber containing oil. A rod having a head that is pressed against the timing belt or the like is inserted in the body of the tensioner so as to form a small oil chamber. A piston is received in the body of the tensioner. Normally, the piston bears against the plunger. If oil should leak from the large oil chamber, then the plunger will move downward, permitting the piston to engage the rod. Thus, the rod is locked.
