The invention relates to a fluid circulation valve (10) having a body delimiting a duct (2) and comprising a flap (3) mounted such that it can pivot on an axis (4) dividing said flap (3) into a first part (5) and a second part (6), said flap (3) being able to pivot between an open position that allows fluid to pass into the duct (2), and a closed position that prevents said passage, and for which the second part (6) of said flap (3) comes into abutment against a seal (7). Said seal (7) has depression means (11, 12) downstream of the second part (6) of the flap (3) in order to increase the force with which said second part (6) is pressed against said seal (7). |
