Abstract
In a hydraulic tensioner, a tensioner housing is provided with an oil outflow channel communicating with a high pressure oil chamber formed by a plunger and the tensioner housing. A control valve in the oil outflow channel can be adjusted manually or automatically to optimize the damping performance of the tensioner in different engines and under different operating conditions, thereby obviating individualized machining of tensioner components to achieve optimum damping.
