    • In a cooling water circuit system, cooling water pumped by a mechanically-driven first water pump circulates in a cooling water circuit, and flows through a radiator and a heater core in parallel in the cooling water circuit. An electrically-driven second water pump is disposed in the cooling water circuit at a position where cooling water to be supplied to the radiator from the first water pump and cooling water to be supplied to the heater core from the first water pump flow together. A check valve is provided in the cooling water circuit in parallel with the second water pump so that cooling water flows in one way from a water suction side of the second water pump toward a discharge side thereof. Thus, when the second water pump is operated, a total amount of cooling water pumped by the first water pump and the second water pump can flow through the radiator and the heater core. As a result, the cooling water circuit system can improve engine-cooling effect in the summer, while improving heating effect of a passenger compartment in the summer.
    • 在冷却水回路系统中,由机械驱动的第一水泵泵送的冷却水在冷却水回路中循环,并且在冷却水回路中流过散热器和加热器芯。 电驱动的第二水泵设置在冷却水回路中,从第一水泵向散热器供给的冷却水和从第一水泵供给到加热器芯的冷却水一起流动。 在与第二水泵并联的冷却水回路中设置止回阀,使得冷却水从第二水泵的吸水侧向排出侧单向流动。 因此,当第二水泵操作时,由第一水泵和第二水泵泵送的冷却水的总量可以流过散热器和加热器芯。 结果,冷却水回路系统可以在夏季提高发动机冷却效果,同时提高夏季乘客车厢的加热效果。

    • To be able to control minute flow in a heat exchanger flow control valve without requiring a minute opening portion, an opening surface area of a hot-water inlet pipe into which hot water flows from an engine is restricted by a first restricting portion of a control passage provided in a needle valve of a flow control valve, and along with this, an opening surface area of a hot-water outlet pipe connected to an inlet side of a heat exchanger for heater use is restricted by a second restricting portion of a control passage formed in the needle valve, and a middle portion of these two control passages is constantly connected to a bypass circuit by a third restricting portion. Pressure of the middle portion thereof can thereby be lowered, pressure applied to the heat exchanger can be adequately reduced, and for this reason minute flow through the valve can be controlled even without establishing a minute opening portion using the needle valves Also, change in heat-exchanger hot-water flow can be reduced by structuring the first and second restricting portions in a configuration whereby flow constant is reduced as amount of flow increases and, along with this, structuring the third restricting portion in a configuration whereby flow constant is maintained substantially uniformly even if amount of flow increases.
    • 为了能够在不需要微小开口部的情况下控制热交换器流量控制阀中的微小流量,热水从发动机流入的热水入口管的开口面积受到控制的第一限制部分的限制 设置在流量控制阀的针阀中的通道,与此同时,连接到用于加热器使用的热交换器的入口侧的热水出口管的开口表面区域受到控制的第二限制部分的限制 通道形成在针阀中,并且这两个控制通道的中间部分通过第三限制部分恒定地连接到旁路回路。 因此能够降低其中部的压力,能够适当地降低施加到热交换器的压力,因此即使不使用针阀形成微小的开口部,也可以控制通过阀的微小流量。另外,热量的变化 换热器热水流可以通过以如下结构来构造第一和第二限制部分来减少流动常数随着流量的增加而减小的结构,并且与此同时,构造第三限制部分的结构使流量常数保持在基本上 均匀,即使流量增加。

    • A heating apparatus of a re-heat type for an air conditioning system for a vehicle provided with an internal combustion engine. The heating apparatus includes a flow control valve for controlling an amount of an engine hot water directed to a heat exchanger for heating. When the degree of the opening of the flow control valve is 2/8 or less and when the target degree of the opening of the flow control valve is 2/8 or more, a control of the degree of the opening of the flow control valve to the target opening plus a predetermined overshoot amount is initially executed, which is followed by a control to the target opening. When both of the initial and target opening is larger than 2/8 or the initial and target opening are identical, the overshoot control is not carried out, i.e., the degree of the opening of the flow control valve is directly controlled to the target value.
