<p>A tensioning arrangement for a chain (2) the like incorporated in a transmission (1) intended to be driven in an endless path. The tensioning arrangement comprises a spring element (31) which acts on a piston (21) moving it outwards to tension the chain when the transmission (1) is not in operation. The tensioning arrangement is moreover designed with a space (26) which is supplied with oil when the transmission is in operation, in which connection the oil imparts to the piston (21) a limited inward movement to slacken the chain.</p> |
