    • To control fluctuation of blown air temperature of a heat exchanger to a small value without adding a movable mechanism such as a variable restricting valve, a heat exchanger for heating air by exchanging heat between hot water supplied from a water-cooling type engine and air, a flow control valve for controlling a hot water flow amount to the heat exchanger and a bypass circuit for allowing hot water to flow while bypassing the heat exchanger are provided. A pressure-responsive valve is provided on the bypass circuit and an opening degree of the bypass circuit corresponding to a pressure rise of the hot water is increased. The flow of returning hot water from the heat exchanger is blocked by the flow of the bypass side hot water at a merging portion where the bypass side hot water discharged from the pressure-responsive valve merges with the returning hot water discharged from the heat exchanger.

    • A flow-quantity control valve controlling hot-water flow to a heat exchanger and a bypass circuit allowing hot water to bypass the heat exchanger are provided along with a pressure-actuated valve in the bypass circuit which is responsive to a pressure increase of hot water from an engine. Inlet-side opening portions, outlet-side opening portions, and a bypass-side opening portion are provided in a control passage of a valve body of the flow-quantity control valve. Main flow of dynamic pressure of hot water sprayed from portions on a small opening-degree side act upon a valve body side of the pressure-actuated valve. Due to this, dynamic pressure of the hot water in a small opening-degree region of the flow-quantity control valve can be effectively used to increase a valve-lift quantity of the pressure-actuated valve, thereby reducing a fluctuation range of blown-air temperature of the heat exchanger. Also, the flow may be bent so that hot-water flow having a high dynamic-pressure component from the hot-water inlet pipe is not applied directly to the valve body of the differential-pressure valve; thus, lift of the differential-pressure valve can be prevented from becoming excessive, and a drop in heat-exchanger blown-air temperature at a predetermined opening-degree position of a flow-quantity control valve can effectively be suppressed.
    • 控制向热交换器的热水流动的流量控制阀和允许热水绕过热交换器的旁路回路与旁路回路中的压力致动阀一起设置,其响应于热水的压力增加 从发动机。 入口侧开口部,出口侧开口部和旁通侧开口部设置在流量控制阀的阀体的控制通路中。 从小开度侧的部分喷射的热水的主动力流动作用在压力致动阀的阀体侧。 由此,可以有效地利用流量控制阀的小开度区域中的热水的动态压力来增加压力致动阀的气门升程量,从而减小吹出 - 热交换器的空气温度。 此外,流动可以弯曲,使得来自热水入口管的具有高动态压力分量的热水流不直接施加到差压阀的阀体; 因此,可以防止差压阀的升高变得过大,并且可以有效地抑制流量控制阀的预定开度位置的热交换器吹出空气温度的下降。

    • According to the present invention, the cooling apparatus is equipped with a thermostat for opening or closing a water passage between a radiator and a water-cooled engine and a cooling water passage switching valve for switching a water introducing passage for introducing the cooling water around a thermosensitive member of the thermostat. When the engine is in a high-load operating condition and when the temperature of the cooling water is equal to or higher than a predetermined temperature, the cooling water immediately after having flowed out of the water-cooled engine flows into around the thermosensitive member of the thermostat by the operation of the cooling water passage switching valve. As a result, the thermostat is operated in response to the temperature of the high temperature cooling water having flowed out of the water-cooled engine, and the set temperature of the cooling water by the thermostat can be shifted to a lower temperature. In this way, it is possible to prevent preferably an excessive rise in the temperature of the cooling water not only when the engine is in a high-load operating condition but also when the engine is in a state of hot soak such as in idling after the vehicle has travelled on an upward slope with a low speed.

    • An air conditioning apparatus for a vehicle includes a heat exchanger for heating air to be blown into a passenger compartment of the vehicle using hot water as a heating source, a plurality of electric heating members formed integrally with the heat exchanger, and a control unit for controlling electric power supplying to the electric heating members and an amount of air blown from a blower.

Thus, even when number of the electric heating members to be turned on is changed, the temperature of air blown into the passenger compartment can be set to the target temperature by controlling the amount of air blown from the blower. As a result, the passenger compartment can be effectively quickly heated using the electric heating members.
