Abstract
A cooling system for an internal-combustion engine which is cooled by means of a liquid coolant and is arranged in a circulating system having a coolant radiator, to which circulating system at least one heat exchanger of an accessory device is connected by means of a switching valve. As a switching element for switching the valve element, a thermostatic working element is used which is loaded by means of a restoring spring, is acted upon by the coolant and is provided with an electric heater. The thermostatic working element contains an expansion material which is designed to a switching temperature which is higher than a maximal operating temperature of the coolant flowing to the thermostatic working element.
