FLAP FOR SHUTTING OFF A DUCT OF AN INTERNAL COMBUSTION ENGINE

摘要

The invention relates to a flap for shutting off a duct along which a fluid flows in an internal combustion engine and which is designed to be moved between an open position and a position in which it shuts off the flow of fluid along the duct. The flap is made of a metal alloy of which the mean coefficient of expansion for temperatures ranging between 0 and 300 degrees (°C) is less than or equal to 5.2 × 10-6 per degree Celsius (°C-1).
