Abstract
A hydraulic chain tensioner for an internal combustion engine includes a support body forming a cylindrical housing which receives a piston slidable in the housing and which carries a pressure pad acted upon by the piston and arranged to come into contact with the chain. A high-pressure chamber is defined by the housing and the piston. A source of pressurized hydraulic liquid supplies the tensioner with lubricating liquid and completes the filling of the high-pressure chamber. The high-pressure chamber is connected to the ambient surroundings by gas-purging orifice
