させることができる等の効果が得られる。If there is one thing in this invention, the thermally-responsive valve has a main valve opening temperature of 0.1.1
Equipped with an auxiliary valve that opens at a lower temperature than the 6, stable water temperature can be obtained without impairing warm-up performance, and overshoot of cooling water temperature can be eliminated.
It can prevent thermal distortion cracks in the engine cylinder head, etc., and gasket blow-out.In addition, in the case of conventional heat-responsive valves, when the cooling water temperature rises rapidly due to open neatness, the driver's instrument panel The heat gauge installed on the panel to indicate the cooling water temperature rose, causing confusion for the driver, but this invention does not overshoot, so this problem can be solved, and furthermore, the main thermal response expansion and contraction The main valve opened by the device 4 and the auxiliary thermal response expansion and contraction device 8
Since the auxiliary valve, which is opened by the It can be easily installed in the engine cooling water circulation path with interchangeability, and when the auxiliary valve opens, the flow of cooling water is generated toward the center of the thermally responsive valve, so the temperature around the main thermally responsive expansion and contraction device 4 increases. In addition to uniform distribution, the auxiliary heat-responsive expansion device 8 can be made small, so it can be made with good thermal response, and the heat-response expansion device can be placed concentrically with respect to the main valve seat. It is also possible to use a bottom bypass type valve, 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.
