Abstract
A valve comprises a body having a gas inlet and outlet, a flap in the body,—a drive shaft which is rigidly connected to the flap, an actuator having a motor shaft, and a coupling of the motor shaft and the drive shaft. A mounting for the actuator on the body comprises a side wall defining a cavity and closed in part at angular sectors facing towards the inlet and towards the outlet. The wall has openings for circulating air between the inside and the outside of the cavity. A thermally insulating partition is between the body and the actuator and has a surface area which is greater than 50% of a cross section of the wall taken in a plane which is perpendicular to the axis of the shaft, and has an opening for receiving the shaft with a gap. A plate is connected to the shaft, which is axially interposed between the partition and the actuator, and covers the gap.
