As shown in FIG. 10 (a), the thermostat 丨 〇〇 closes the coolant flow path 11 〇 between the time when the engine starts and the time when the temperature in the engine E becomes an appropriate temperature. . σ means' because the coolant from the engine E does not go to the radiator r, it passes through the bypass passage 110A and then circulates to the engine E (refer to the arrow in Figure 10), and it reaches the proper temperature early and becomes within the engine E. After the temperature is adjusted, as shown in FIG. 10 (b), the valve body 103 of the thermostat 100 is opened, and the coolant flow path of the radiator R1 (1) is opened. As a result, the cold liquid passes through the radiator R and is cooled in the engine E: circulation (refer to the arrow in FIG. 10 (b)) to the engine E to maintain a proper temperature. Problem to be Solved by the Invention However, since the conventional thermostat is located inside the coolant flow path, in order to maintain the constant flow rate of the coolant, it is necessary to make the official diameter of the cold liquid flow path of the thermostat thicker. As a result, the diameter of the coolant flow path must be changed

Description of the invention (9) is always in contact with the fixed cover. In fact, the element (valve body) 2a resists the rebound force of the coil spring 4 and is pushed down due to the relative movement of the piston 2g. Then, when the thermal valve 2 slides downward, the inlet opening 1a and the outlet opening 1b of the casing 1 outside the use element (valve body) 2a becomes closed, and the flow path area f A communicates. As a result, the coolant flows from the radiator side to the engine side as shown by a blank arrow in FIG. 6. In addition, in order to make the forced self-closing state independent of the liquid temperature of the coolant into an open state, electric power is supplied from the connection wire 10a, and the wax case 2c is heated by a thermoelectric element. The inlet opening portion 1a of the case 1 and The outlet opening jb is opened, and the flow path area FA becomes connected. Next, the effect of the thermostat A from the open state to the closed state will be described. When the engine is stopped, the water pump is stopped and the circulation of the coolant in the coolant flow path 3 is stopped. The temperature of the cooling liquid decreases with time, and this temperature change is also transmitted to the wax 2 b through the element (valve body) 2 a and the wax shell 2 c. As the temperature decreases, the expanding wax 2b contracts, and the biasing force of the coil spring 4 that always biases the thermal valve 2 upwards slides the thermal valve 2 upwards. As a result, the outer peripheral surface of the element (valve body) 2a finally closes the inlet opening portion la and the outlet opening portion lb of the case 1 and closes the flow path area (see FIG. 5). Next, a second embodiment of the present invention will be described with reference to FIG. 7. In addition, Fig. 7 is a longitudinal sectional view showing a state where the buried thermostat is installed in the internal combustion engine, and shows a state where the flow path region is cut off.
