Abstract
The invention relates mainly to a tensioner for a transmission belt, in particular a power transmission belt, e.g. a V-belt or a ribbed belt, and also for a toothed belt used for timing purposes in the automobile industry. The invention also relates to a transmission system including such a tensioner. According to the invention, a tensioner for a belt comprising two fixing members, in particular eye links mechanically interconnected by a spring, and two chambers containing fluid and hydraulically interconnected via a connection including a passage of calibrated section that determines a degree of damping provided by the fluid flowing from one chamber into the other under drive from pumping member whenever there is a variation in the distance between the two fixing members, wherein the two chambers are substantially coaxial.
