  • Valve for motor vehicle exhaust muffler
    Patent number: 9027592
    Abstract: A valve comprises a support including an exhaust gas passage opening, a plug able to move by tilting between a plugging position and a release position of the passage opening, and an elastic strip for returning the plug to its plugging position. The elastic strip has a first end fastened to the support and a second end bearing on the plug. The second end is able to slide on the plug between a first position, in which the plug is in the plugging position, and a second position, in which the plug is in the release position. The plug includes a stop forming a hard spot that cooperates with the second end of the elastic strip when the elastic strip is in the first position, so that this stop forms an obstacle for movement of the second end of the elastic strip from the first position to the second position.
