The invention relates to an engine control valve including a body defining an inner duct and comprising a flap (10) mounted such that it can pivot by means of a shaft (12) of the flap (10), said flap (10) including a first portion (11). The flap can pivot between an open position allowing the passage of gas into the duct and a closed position in which the flap (10) comes into contact with a seal (1) that is solidly connected to the body of the flap. The outer contour of the seal (1) surrounds the outer contour of the flap (10), said seal (1) comprising an opening (6) and a solid portion (3). The above-mentioned first portion (11) seals the opening (6) in the seal (1) when the flap (10) is in a closed position. The flap (10) comprises a boss (18), separate from the first portion (11), which is positioned such as to remain in contact with the solid portion (3) of the seal (1) when the flap (10) pivots between an open position and a closed position or vice versa. |
