ABSTRACT:
The chain for transmitting the drive between two overhead camshafts of a combustion engine for motor vehicles has an associated tensioning device comprising a rod-like support body fixed to the head in a position offset from the plane of the chain and a bush which can slide coaxially on the rod and is formed with a bracket carrying a shoe in sliding pressure contact with a free pass of the chain. The tensioning device incorporates means for automatically taking up the play between the shoe and the chain, including frictional axial positioning means between the bush and the rod for enabling the braked sliding of the former relative to the latter under the action of resilient and hydraulic thrust means.
