Abstract: The invention relates to a cooling device for an engine (1) exhaust gas recirculation circuit, notably that of a motor vehicle, said circuit comprising a valve (2) for controlling the circulation of said gas, said device comprising a heat exchanger (3), known as the EGR exchanger, intended to allow an exchange of heat between the exhaust gases passing through said recirculation circuit and a coolant fluid, and means (4) of cooling said valve. According to the invention, said device comprises a cooling loop (5), known as a high-temperature cooling loop and configured so that said valve cooling means (4) have a first fluid passing through them, and a second cooling loop (12), known as a low-temperature cooling loop and configured so that the EGR exchanger (3) has passing through it a second fluid at a temperature lower than that of the first fluid.

Abstract: 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.

Abstract: A fluid flow valve that includes a movable closure member and a body that includes a projecting part that receives the closure member. The body is designed to be attached to a support in such a way that the projecting part is introduced into a housing in the support. In addition, the body is designed to allow the valve to be secured to the support in a direction transverse to a longitudinal direction of extension of the projecting part. The invention is suitable for the recirculation of exhaust gases of motor vehicle engines.
