Abstract
A valve has a body, a fluid inlet duct delimited by the body, two fluid outlet ducts into which the fluid inlet duct opens, an intersection formed by the two fluid outlet ducts, a butterfly valve disposed in the intersection, and a motor, to which the butterfly valve is connected, for actuating the butterfly valve between a first extreme position in which the butterfly valve directs the fluid mainly toward the first outlet duct and a second extreme position in which the butterfly valve directs the fluid mainly toward the second outlet duct. The motor is placed between the outlet ducts in the vicinity of a connecting zone connecting the two outlet ducts to one another. The butterfly valve is mounted in front of the connecting zone so that the butterfly valve forms a screen against the fluid for the connecting zone.
