<p>A hydraulic tensioning system (1) for a belt drive, including a cylinder (4) that is designed to receive a linearly displaceable piston (6), these elements together forming a piston-cylinder unit (3) and delimiting a pressure chamber (10) that is filled with hydraulic fluid. A relative movement between the piston (6) and the cylinder (4) causes the hydraulic fluid to be exchanged between the pressure chamber (10) and a storage chamber (12) or vice versa. At least one annular spring valve (14), which opens depending on the pressure, is positioned in an outflow section (17) for the hydraulic fluid between the pressure chamber (10) and the storage chamber (12) as a one-way valve.</p> |
