ABSTRACT:
A tensioner for a power transmission belt that is adapted to be operated in an endless path and comprising a support unit for being fixed relative to the belt, a belt engaging unit carried by the support unit and being movable relative thereto, a mechanical spring unit operatively associated with the support unit and the belt engaging unit for urging the belt engaging unit relative to the support unit and against the belt with a force to tension the belt, and a fluid dampening unit operatively associated with the support unit and the belt engaging unit to dampen the movement of the belt engaging unit relative to the support unit in at least one direction of movement thereof, the fluid dampening unit comprising a piston and cylinder unit. The mechanical spring unit comprises a pair of coiled compression springs with their longitudinal axes disposed in substantially parallel side-by-side spaced relation. The fluid dampening unit is generally disposed between the springs and in substantially parallel relation therewith. The belt engaging unit and the support unit have a tongue and groove arrangement for providing sliding movement therebetween.
