ABSTRACT:
A liquid-cooled internal combustion engine with a control of the cooling medium temperature of its cooling medium circulation by a thermostatically operating mixing valve which includes a mixing chamber in open communication with the suction connection of a circulating pump interconnected into the cooling medium circulation, a return chamber adapted to be closed off with respect to the mixing chamber by a return control valve and connected with the cooling medium outlet of a radiator by way of a radiator return line, and a by-pass channel connected with the cooling medium outlet of the internal combustion engine and adapted to be closed off with respect to the mixing chamber by a by-pass control valve; the cooling medium outlet line of the mixing valve is connected by way of a radiator inlet line with the radiator inlet of the radiator while the return chamber is connected by way of a vent connection with an auxiliary chamber fed with cooling medium by the circulating pump by way of the radiator inlet line for the formation of a liquid seal; the auxiliary chamber, which in its turn is provided with a vent connection leading to a geodetic high-point of the cooling medium circulatory system serving for the air separation, is located in series between two vent lines, of which one is connected to the return chamber and the other to the radiator inlet line.
