Abstract
A tensioner for a chain, includes a tensioner piston bearing upon a chain and guided by a cylinder for movement in the direction of the chain. The cylinder and the piston define a pressure chamber for receiving hydraulic fluid, wherein hydraulic fluid is able to escape from the pressure chamber via a leakage gap. A control member is provided to at least reduce the leakage gap in size, when a pressure in the pressure chamber increases.
