The invention relates to a gas distribution device (1) for an EGR circuit comprising a cylindrical body (2) diametrically intersected by a dividing wall (11) dividing it into two chambers (12, 13), a first distribution orifice (5) opening into the first chamber (12), a second distribution orifice (6) opening into the second chamber (13), an inlet (3) positioned in a first flat circular end (9) of the body (2) and an outlet (4) positioned in a second flat circular end (10) of the body (2) and distribution means (14, 15) comprising a first (14) and a second (15) flap in the form of an angular sector, these being positioned at right angles to the dividing wall (11), angularly opposite each other and able to turn while at the same time remaining in contact with an opposite side of the dividing wall (11). This device makes it possible to reverse the direction of flow through an associated heat exchanger or to short-circuit said exchanger. |
