  • Patent number: 5637047
    Abstract: There is described a hydraulic tensioner (1, 101) for endless transmission elements, in particular a chain tensioner for internal combustion engines. The tensioner includes a housing (2, 102), a pressure chamber (3, 103) arranged in the housing, a piston (4, 104) which is movable in the pressure chamber (3, 103), a hydraulic fluid supply to the pressure chamber (3, 103), a check valve (20, 120) which is arranged within the hydraulic fluid supply and is acted upon by pressure in the pressure chamber (3, 103), and a means (11, 111) for automatically reducing the pressure in the pressure chamber (3, 103). To provide such a tensioner with a pressure-relief valve (11, 112) for automatically reducing pressure in the pressure chamber (3, 103), i.e., in a manner which is simple under constructional and technical manufacturing aspects and also reliable, the check valve (20, 120) should be connected to the valve member (12, 122) of the pressure-relief valve (11, 111).
