Abstract (en)
[origin: EP0374038A1] Device for the liquid cooling of an internal-combustion engine having a main cooling circuit comprising a radiator (4) connected to the engine (1) by means of a liquid intake pipe (5) and a return pipe (3), means (2) for circulating the liquid between the engine (1) and the radiator (4), and a thermostatic valve (6) capable of interrupting the circulation of liquid when the temperature of the latter is below a given value, at least one secondary cooling circuit connected in parallel with the main circuit and comprising a low-volume degassing chamber (14) connected to the engine (1) by means of a liquid intake pipe (17) and an offtake pipe (18), and means (2) for circulating the liquid between the engine (1) and the degassing chamber (14), and an expansion vessel (8) connected to one of the cooling circuits. The expansion vessel (8) is connected to the main cooling circuit, and one (19) of the walls of the degassing chamber (14) has a port (20) connected to the expansion vessel (8) by means of a shutter (21 or 26) designed to open when gas is present in the chamber (14). <IMAGE>
