Abstract
A hydraulic tensioning element for a traction mechanism drive, which has a cylinder, an axially movable piston guided in the cylinder, a spring element disposed between the cylinder and the piston, a pressure chamber configured in the cylinder, a storage chamber configured in the piston for a hydraulic fluid, and a valve enabling an exchange of the hydraulic fluid between the pressure chamber and the storage chamber as a function of an actuating movement of the piston. The piston and the cylinder are configured such that the damping generated by the piston movement is substantially independent of the temperature.
