Abstract (en)
[origin: WO2017134368A1] The invention relates to a method for protecting a coolant circuit of an engine (5) against an internal overpressure in an outlet casing (3) supplied with fluid at the outlet of the engine (5) and comprising at least three outlets (31 to 34) respectively to a radiator (4), a unit heater (1) and a return to the engine (5), the flow of fluid to the engine (5) being interrupted on exceeding a first fluid temperature, termed the regulation temperature, and the flow of fluid to the unit heater (1) being interrupted on exceeding a second fluid temperature (T2) greater than the first, in order that all the fluid leaving the casing (3) is fed to the radiator (4). Above the second temperature (T2), when the pressure (Pb) prevailing in the casing (3) is greater than a maximum permissible pressure (Pmaxadmi), a part of the flow to the radiator (4) is diverted to the unit heater (1).
