Abstract
A chain tensioner comprises a body which is received in a bore formed through a side wall of a chain case, and includes a generally cylindrical portion. A plunger is slidably received in the cylindrical portion so as to press a timing chain. A check valve is arranged in the body. A damping chamber is defined by the cylindrical portion and the plunger, and is fluidly communicated with an oil pump via an oil supply passage. On the other hand, an oil reservoir is defined by the bore and the body, and is fluidly communicated with the damping chamber through the check valve via an oil passage, and also with the damping chamber via a flow restrictor.
