Zusammenfassung:A sealed tensioner is used in an automotive application to keep a belt or chain under its intended tension as it wears and stretches. The sealed tensioner is hydraulic but lacks an outside oil supply. The sealed tensioner, in an example, includes an outer body having a first bore. A cartridge body is received in the first bore. The cartridge body has a second bore. A piston is carried in the second bore. A check valve is situated between a low pressure reservoir and a high pressure chamber. One or more baffle walls are located at the low pressure reservoir. The baffle wall(s) block an air pocket in the low pressure reservoir from entering the high pressure chamber.
