Abstract
A chain tensioner acts by means of tensioning elements on the taut section and the slack section of an endless chain whcih preferably cooperate with chain sprockets of parallel cam shafts of an internal combustion engine. The tensioning elements are provided with relatively movable pistons which are nested one within the other, have a common pressure space and are accommodated in a cylindrical housing. The housing is provided with a fastening eye which extends axially parallel to the housing whereby the fastening eye is secured at an internal combustion engine housing part by a bolt. Oil is conducted to the pressure space between the pistons by way of the bolt.
