ABSTRACT:
A tensioning arrangement for a chain incorporated in a transmission and intended to be driven in an endless path. The tensioning arrangement comprises a spring element that acts on a piston to move it outwards to tension the chain when the transmission is not in operation. The tensioning arrangement is also designed with a space that is supplied with oil when the transmission is in operation, in which connection the oil imparts to the piston a limited inward movement to slacken the chain.
