The thermostat If to speak упрощенно the thermostat defines, the cooling liquid will be or not to circulate. That is, it defines, whether it is necessary a cooling liquid to pass on a small or big contour (see about it also in the beginning of this chapter). Naturally, the thermostat operates a stream of a cooling liquid depending on its temperature. It occurs by means of the sleeve filled with special wax and the plate of the valve strengthened on it.
At heating of a cooling liquid wax thaws, extends and opens a valve plate. Until the temperature of a cooling liquid rises, the thermostat opens access to cold water from a radiator more and more. If the working temperature, on the contrary, falls, the spring in the thermostat again presses a valve plate in position "is closed" (zu), closing thereby access to cold water before working temperature. |
