Abstract
An exhaust valve assembly for controlling the flow of exhaust comprising a hollow elongated member, desirably in the form of an exhaust pipe or component thereof, having an open end, a flap associated with the open end and a spring having two ends. The flap is pivotable between a first position to close the open end and a second position to open the open end, and is adapted to pivot toward the second position when the exhaust gas within the elongated member achieves a predetermined pressure. One end of the spring is associated with the flap and the other end of the spring is associated with the elongated member along the length of the elongated member. The spring biases the flap toward the first position. The spring desirably extends generally parallel to a longitudinal axis of the elongated member when the flap is in the first position. The flap desirably includes a lateral edge having a hook and the one end of the spring is mounted to the hook. The exhaust valve assembly further includes a magnet associated with the open end of the elongated member for biasing the flap toward the first position when the pressure of exhaust gas within the elongated member is less than the predeter…
