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…
