ABSTRACT:
A circuit is provided for thermally regulating a vehicle equipped with an electric retarder (2), using the forced circulation of a liquid successively through the engine (1,5) of the vehicle, a radiator (7) and a drive pump (6). An auxiliary circuit section (10) is provided comprising a heat exchanger (11) adapted to remove heat coming from the retarder or to yield up heat to the air current thrown back by the rotor of this retarder and a three-way electro-magnetic valve (12) adapted to bring this section (10) into circuit depending on whether the retarder is energized or not and/or whether the temperature of the liquid in the radiator exceeds a certain threshold or not. A second auxiliary circuit section (15-17) allows the passenger space of the vehicle to be heated.
