水を送ることができなくなる。 In an automobile engine coolant circulation circuit that is equipped with a radiator circuit, a car heater circuit, a bypass circuit, and a heat-responsive valve that controls opening and closing of the radiator circuit, the water flow resistance of the car heater circuit is relatively large, so the water flow resistance of the bypass circuit is increased. This prevents hot water from the car engine from being sent to the car heater circuit.
このため従来は、バイパス回路を冷却水循環用
ポンプの手前で常時直径6.4mmの円の面積に相当
する断面に絞つている。 For this reason, in the past, the bypass circuit was always narrowed down to a cross section equivalent to the area of a circle with a diameter of 6.4 mm before the cooling water circulation pump.

る。 However, if the bypass circuit is throttled even when the heat-responsive valve is closed and circulation in the radiator circuit is stopped, the amount of water flowing through the bypass circuit will be insufficient, easily causing temperature unevenness in the automobile engine, and the pump There is a problem in that the inlet side becomes negative pressure and bubbles are generated, which causes cavitation and makes the pump case, impeller, etc. more likely to corrode.

る。 In the thermally responsive valve of the first embodiment, when the water temperature around the container 5 is below a certain level, for example below 60°C,
As shown in FIG. 2, since the thermally responsive expansion and contraction device 3 is shortened, the main valve body 7 closes the pipe 14, and the water passage hole 30 in the throttle valve body 9 is separated from the bypass pipe 15. Because of the protrusion, the bypass line 15 is fully opened, so that the cooling water of the automobile engine 12 does not pass through the radiator 13, but instead flows through the water passage hole 30 and the amount of cooling water set by the annular passage formed by the gap δ. circulates through the bypass circuit. Furthermore, when the bypass circuit is fully opened in this manner, the water flow resistance of the bypass circuit is considerably greater than the water flow resistance of the car heater circuit, so that almost no cooling water from the automobile engine 12 is sent to the car heater 19. It is circulated through a bypass circuit.

つてバイパス回路の両量が絞られる。 Next, when the water temperature around the container 5 reaches, for example, 60°C to 80°C, as shown in FIG. 30 is inserted into the bypass line 15, and a small amount of cooling water is circulated through the bypass circuit, defined by an annular passage of small cross-sectional area due to the gap δ. That is, both volumes of the bypass circuit are throttled by the throttle valve body 9.
このようにバイパス回路の流量が絞られると、
その通水抵抗が大きくなるので、自動車エンジン
１２の温水がカーヒータ回路を循環する。 When the flow rate of the bypass circuit is reduced in this way,
Since the water flow resistance increases, hot water from the automobile engine 12 circulates through the car heater circuit.
また前述のように60℃〜82℃程度の水温で主弁
体７が閉じられているときでも、バイパス回路に
少量の循環流を確保しておくことにより、自動車
エンジンの焼付事故を防止することができる。 Furthermore, as mentioned above, even when the main valve body 7 is closed at a water temperature of about 60°C to 82°C, by ensuring a small amount of circulation flow in the bypass circuit, it is possible to prevent a seizure accident in the automobile engine. I can do it.

回路をも少量の温水が循環する。 Next, when the water temperature around the container 5 rises above 82° C., for example, as shown in FIG.
1, the main valve body 7 is moved open. Therefore, hot water from the automobile engine circulates through the radiator circuit in addition to the car heater circuit, and a small amount of hot water also circulates through the bypass circuit.

を示している。 The characteristic line in FIG. 5 shows the relationship between the water temperature and the amount of expansion of the thermally responsive expansion device 3. At point A, the throttle opening movement of the throttle valve body starts, and then at point B, the main valve body 7 starts moving. Opening movement is started. The characteristic line in FIG. 5 shows the relationship between the water temperature and the bypass flow rate by the throttle valve body 9. The characteristic line in FIG. 5 shows the relationship between water temperature and bypass flow rate in a conventional cooling water circulation circuit.

の熱応動弁の場合と同様である。 FIG. 6 shows a heat-responsive valve according to a second embodiment of the present invention, in which a bypass closing annular valve body 31 is slidably fitted into the end of the container 5 on the throttle valve side. A spring 32 is interposed between the annular valve body 31 and the large diameter portion of the container 5, and the spring 32
The annular valve body 31 is pressed against the upper end surface of the throttle valve 9 by the elasticity of the valve, but the other structure is the same as that of the thermally responsive valve of the first embodiment.

９がさらにバイパス管路内に挿入されていく。 In the case of the heat-responsive valve of the second embodiment, when the water temperature further increases after the main valve body 7 is opened to a predetermined position, the flange of the annular valve body 31 opens to the bypass pipe 1.
5, the bypass circuit is almost completely closed, so that hot water from the car engine is circulated only to the radiator circuit and the car heater circuit. Furthermore, if the thermally responsive expansion and contraction device 3 is further extended after the flange of the annular valve body 31 abuts against the end face of the bypass conduit 15, the spring 32 is compressed by the expansion movement, and the throttle valve body 9 is compressed. It is further inserted into the bypass pipeline.

られる。 In the case of the second embodiment, for example, the water temperature is 60°C to 85°C.
In this range, the water passage hole 30 enters the bypass pipe 15 and the bypass circuit is throttled, and when the water temperature rises above 85° C., the bypass circuit is almost completely closed.

With the radiator circuit closed,
Moreover, when the water temperature is relatively low, the throttle valve body 9 is placed in the open position, so even when the radiator circuit is closed by the main valve body 7, a large flow rate in the bypass circuit can be secured. Therefore, it is possible to almost eliminate temperature unevenness in the automobile engine, and when the water temperature is relatively low, there is no negative pressure on the inlet side of the circulation pump, which prevents cavitation and air bubbles from forming in the pump. It is possible to prevent or almost eliminate corrosion of the valve and impeller, etc., and when the water temperature becomes relatively high with the radiator circuit closed by the main valve body 7, the throttle valve body 9
This narrows the bypass circuit and increases its water flow resistance, so relatively high temperature water, which is slightly lower than the temperature at which the radiator circuit is opened by the main valve body 7, can be circulated to the car heater and used effectively. Effects such as this can be obtained.
