Abstract
The invention relates to a cooling device for an engine () exhaust gas recirculation circuit, notably that of a motor vehicle, said circuit comprising a valve () for controlling the circulation of said gas, said device comprising a heat exchanger (), 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 () of cooling said valve. According to the invention, said device comprises a cooling loop (), known as a high-temperature cooling loop and configured so that said valve cooling means () have a first fluid passing through them, and a second cooling loop (), known as a low-temperature cooling loop and configured so that the EGR exchanger () has passing through it a second fluid at a temperature lower than that of the first fluid. The invention also relates to an assembly of an exhaust gas recirculation circuit and of such a cooling device, and to a system for supplying an engine, notably a supercharged diesel engine, with charge gases and comprising an engine air supply circuit and such an assembly.
