Beschreibung
Zusammenfassung:	The invention relates to a valve (1) for regulating a gas flow in an EGR loop of a gas supply circuit of a vehicle engine, including a gas inlet (3), a first gas outlet (4) for directly feeding the gases into the supply circuit, and a second gas outlet (5) enabling said gases to flow into a pipe (6) passing through a cooler (2) before injecting said gases into said supply circuit, said valve (1) having a rotatable flap (7) capable of pivoting between a first position in which same blocks the second outlet (5) while at the same time opening the first outlet (4), and a second position in which same blocks the first outlet (4) while at the same time opening the second outlet (5). The main feature of a valve according to the invention is that the flap (7) includes a main flat body (11) capable of opening or closing the pipe (6) and that said pipe (6) has a flat rim (20), whereby the main body (11) of the flap (7) bears flatly against said rim (20) when said flap (7) is in the second position thereof.
