Abstract
A tensioner for a power transmission belt is disclosed comprising a return spring associated mechanically with a tensioner roller with which the belt cooperates for controlling the movement of said roller under the action of said spring, wherein the vibrations likely to arise in the belt are damped by a rubber sheath integral with said spring for forming a chamber closed at its ends by seals, one at least of which has a nozzle for the inlet and/or outlet of air into and/or out of the chamber defined by said sheath and said seals.
