摘要： In a liquid-coolant cooling system for an internal combustion engine, of the kind in which a piping by-passing the radiator and put in parallel with respect thereto, is provided, connected by a three-way valve to the radiator inlet piping, the improvement comprising a special throttling valve for the coolant, installed in the radiator-by-passing piping. The special valve allow the rate of flow of liquid through the radiator-by-passing pipe to be increased as the pressure therein is increased. The advantages of the device are to prevent localized overheatings in the engine block and reducing the emission of unburned hydrocarbons when the engine is running cold.
