Abstract: An exhaust line valve for an internal combustion engine. A closure body is arranged in a duct of the valve and is fastened to a shaft. The closure body when closed separates upstream and downstream duct sections. Two projections extend into the duct, each having a valve seat pointing in an opposite direction of the duct. By pivoting the closure body from its closed position, the sealing surfaces of the closure body are raised from their respective valve seats. A polymer seal is arranged on the valve seats and in the closed position the polymer seal sealingly contacts the associated sealing surface of the closure body. A circumferential surface of the shaft or the closure body is located in an edge region of the closure body. The polymer seal contacts in a sealing manner at least a region of the circumferential surface facing the upstream section of the duct.

Abstract: A tensioner uses a low rate torsion spring in a first stage and a high rate torsion spring in a second stage to maintain tension in a chain or belt. The first stage is connected to the second stage by a torque coupling. The high rate torsion spring is maintained in an energized state between a ground and a dead stop to store energy and to provide tension under high loads. In some embodiments, the torque coupling is a damper. In other embodiments, the torque coupling is a clutch. A method stores energy in a high rate torsion spring of a tensioner.
