Working principle of Mercedes-Benz 27 1 warm air water.
The warm air water valve is the warm air switch of the automobile heater. The working principle of the warm air of the automobile heater is that the radiator in the heater is connected with the circulating water of the engine through the inlet and outlet water pipes. The water valve is a circulating path for switching the size of cooling water. Thermostat can make cooling water have three circulation paths: small circulation, large circulation and mixed circulation.
When the water temperature of the engine reaches 349K or above 76℃, paraffin gradually turns into liquid, and its volume increases, forcing the rubber tube to contract, thus generating upward thrust on the lower cone surface of the central rod. Because the upper end of the rod is fixed, the central rod generates downward reverse thrust on the rubber tube and the inductor, overcomes the spring tension, makes the main valve gradually open, and the opening of the bypass valve gradually decreases.
