PURPOSE:To maintain the intra-circuit pressure constant by constituting a circuit of the gas/liquid two-phase flow not maintaining constant the liquid level of a cooling water in a water jacket, and releasing the cooling water to a cooling water storing means outside of the system associate with rise of the intra-circuit pressure when the engine temp. has risen. CONSTITUTION:An oitlet pipeline 6 connected with a water jacket 3 for cooling an engine 2 is led to a gas/liquid separator 4, which is connected with a condenser 10 via a line 8 in communication with the vapor phase 5 in the separator 4. Another line 12 for dispatching the cooling water liquefied is connected with the lower part of this condenser 10, and this line 12 converges with a line 14 in communication with the lower liquid phase 7 of the gas/liquid separator 4 and leads to a water supply pump 16 via a suction side line 13. One of the divergent lines 20 from the discharge side line 18 of this water supply pump 16 is led to the water jacket 3 via No.1 solenoid valve 22 while the other divergent line 24 is put in communication via a solenoid valve to an accumulator 28 for storing temporarily the cooling water in the circulation system 17. |
