Abstract
An exhaust valve includes a body defining a passage and a flap that pivots about an axis relative to the body to selectively close/open the passage. An actuator moves the flap and a device couples the flap to the actuator. This coupling device comprises: a compression spring having a proximal end that rotates about the axis with a first element between the flap and an actuator output shaft and a distal end; a seat engaged with the distal end, while the seat is fixed in rotation about the axis with the first element, and a torsionally-rigid transmission member fixed in rotation about the axis with the first element and that immobilizes the distal end relative to the proximal end in a plane that is orthogonal to the axis. The transmission member has a slot that is elongated parallel to the axis and is traversed by the distal end.
