PCT No. PCT/EP96/03536 Sec. 371 Date Mar. 20, 1998 Sec. 102(e) Date Mar. 20, 1998 PCT Filed Aug. 9, 1996 PCT Pub. No. WO97/13081 PCT Pub. Date Apr. 10, 1997A tensioning device for the chain (3) of an internal combustion engine, for example of a control gear, comprises a guide rail (8), a pivoted tension lever (15) and a tension element (13) which exerts a tensioning force on the sliding block (18) through a compression spring (14). According to the invention, two sliding blocks (17, 18) acting in different directions on the chain (3) are arranged on the tension lever (15) which has a fixed axis of pivot (16). The device of the invention can thus be used in a very small mounting space and is able to compensate large chain elongations.
