摘要:
An internal-combustion engine has a camshaft drive in which the outlet camshaft driven by the crankshaft drives the inlet camshaft via a chain. For the tensioning of the chain, two hydraulic pistons are pressed in opposite directions with respect to one another against the loose end and the load end of the interior side of the chain. For adjustment of the relative camshaft rotating position, the unit consisting of the hydraulic piston and the chain is shifted transversely to the camshafts so that the loose end is shortened and the load end is lengthened, or vice versa.
