Mechanical clamping system for clamping e.g. driving chain in vehicle, has pressure and reservoir chambers connected together over through-holes, piston supported in receiving chamber, where reservoir chamber is expandable against force

摘要

The system (2) has a housing (4) provided with a single-side opened receiving chamber (6), where a clamping piston (18) is movably supported in the receiving chamber. The receiving chamber and the clamping piston commonly enclose a pressure chamber (26). A reservoir chamber (10) is expandable against a return force. The pressure chamber and the reservoir chamber are connected together over through-holes (22, 24). A leakage gap (28) between an inside wall of the receiving chamber and an exterior wall of the piston is sealed over a seal ring (30).
