According to this invention, since the series composite heat-responsive valve is equipped with an auxiliary valve that opens at a temperature lower than the opening temperature of the main valve and has a flow rate lower than that of the main valve, warm-up performance is not impaired. It is possible to obtain a stable coolant temperature and eliminate overshoot of the cooling water temperature, which prevents thermal strain cracks in engine cylinder heads and blow-through of gaskets. In the case of valves, when the coolant temperature suddenly rises due to overshoot, the heat gauge for indicating the coolant temperature installed on the instrument panel of the driver's seat rises, causing confusion for the driver. In the case of , there is no overshoot, so this problem can also be solved.Furthermore, the main valve body 6 is moved in parallel by the main thermally responsive expansion device 4 and opened, and the auxiliary thermally responsive expansion device 8 is moved in parallel. Auxiliary valve body 1 to be opened
0 are arranged in series and concentrically, so
It is possible to secure the required flow rate by setting the diameter of the main valve to be the same as a conventional heat-responsive valve with a limited outer diameter, and it can be easily installed in a conventional engine cooling water circulation path with replaceability. Moreover, when the auxiliary valve opens, the water temperature flows uniformly around the main thermally responsive expansion device 4, so the temperature distribution around the main thermally responsive expansion device 4 becomes uniform, and therefore, the temperature distribution of the main thermally responsive expansion device 4 becomes uniform. Since the temperature sensitivity can be improved and the thermal response of the series composite thermally responsive valve can be improved, and each of the thermally responsive expansion and contraction devices 4 and 8 can be arranged concentrically with respect to the main valve seat 3, It is also possible to use a bottom bypass type, and furthermore, in the case of the series composite heat-responsive valve of the present invention, even if the main valve fails and does not open, the auxiliary valve opens, improving engine safety. Effects such as being able to do this can be obtained.
