燃機関の冷却装置。In a cooling system for an automobile internal combustion engine in which a thermostat is installed in the radiator inlet passage to control the amount of coolant flowing to the radiator according to the coolant temperature, the coolant is placed downstream of the thermostat and upstream of the water pump. A control valve is provided that responds to the engine suction negative pressure and shuts off the passage when the engine is under low load or no-load conditions, while a control valve is installed in the suction negative pressure passage of this side valve to control the temperature of the coolant upstream of the thermostat. A cooling device for an internal combustion engine for an automobile, characterized in that a thermal vacuum valve is provided for introducing atmospheric air into the suction negative pressure passage when the temperature of the coolant exceeds a certain set temperature in response to the temperature.
