ABSTRACT:
A ratchet type tensioner with a buffer mechanism is capable of buffering an impact force applied from a chain side to a plunger, irrespective of the amount of backlash in a ratchet mechanism, and is capable of exhibiting an excellent effect of suppressing vibration of the chain. An inner plunger is inserted in a protrudable and retractable manner into an outer plunger whose backward movement is restricted by a ratchet mechanism. The inner plunger is urged in its protruding direction by means of an inner plunger spring more powerful than a plunger spring which urges the outer plunger in the protruding direction. At one end of inner plunger is an oil storage chamber in communication with a high pressure chamber at the opposite end of the inner plunger through a check valve. A clearance path is provided between the two chambers to allow oil in the high pressure chamber to bypass the check valve and flow through the clearance path.
