Abstract (en)

[origin: FR2904857A1] The device has an oil/liquid exchanger (11) with a bypass line (23) connected to lubrication oil inlet and outlet of the exchanger. Flow of oil through the line is controlled by solenoid valves (24, 26) driven based on a temperature of a coolant e.g. water, at an inlet (4) of a thermostat (3). The valves occupy a position to stop lubrication oil circulation through the exchanger and to circulate the oil in the line at a temperature value. The valves take another position to stop the oil circulation in the line and to allow circulation of the oil in the exchanger at another temperature value.
