Claim:
1. A valve for regulating a gas flow in an EGR loop of a gas supply circuit of a vehicle engine, comprising: a gas inlet; a first gas outlet for directly feeding the gases into the supply circuit; a second gas outlet enabling said gases to flow into a duct passing through a cooler before injecting said gases into said supply circuit; a rotatable flap capable of pivoting between a first position in which blocks the second outlet whilst at the same time opening the first outlet and a second position in which the flap blocks the first outlet whilst at the same time opening the second outlet, the flap comprising a planar principal body capable of opening or closing the duct, said duct having a planar edge such that the principal body of the flap comes to bear in a planar manner against said edge when said flap is located in the second position thereof, the duct forming a loop with an inlet extending the second outlet of the valve and an outlet opening into the region of the first outlet of said valve, the flap having a planar secondary body contiguous with the principal body, said flap being positioned in the valve such that it may pivot about an axis of rotation placed between the principal body and the secondary body, the secondary body being capable of opening or closing the outlet of said duct, wherein the principal body is elongated in a first direction, perpendicular to the axis of rotation; and wherein the secondary body is elongated in a second direction, parallel to the axis of rotation.
