    • A water pump is provided to automatically adjust a pressure difference between front and rear surfaces of an impeller to prevent damage to some components due to excessive pressure difference. A water pump includes a return line(17a), a valve retainer(21), a valve plunger(22), and elastic members. The return line axially passes through an impeller adapter(17). The valve retainer has a hollow center part to be in communication with the impeller adapter and fastened to the impeller adapter. The valve plunger is restrained by the valve retainer to selectively open the return line. The elastic members resiliently support the valve plunger by using the valve retainer. The return line is formed at the impeller adapter to function as a passage for returning cooling water. The impeller adapter is provided to fasten the impeller to a cooling water pump housing.
    • 提供水泵来自动调节叶轮的前表面和后表面之间的压力差,以防止由于过大的压力差导致的某些部件损坏。 水泵包括返回管线(17a),阀保持器(21),阀柱塞(22)和弹性构件。 回流管线轴向通过叶轮适配器(17)。 阀保持器具有中空的中心部分,以与叶轮适配器连通并紧固到叶轮适配器。 阀柱塞被阀保持器约束以选择性地打开返回管线。 弹性构件通过使用阀保持器弹性地支撑阀柱塞。 返回管线形成在叶轮适配器处,用作返回冷却水的通道。 提供叶轮适配器以将叶轮紧固到冷却水泵壳体。

    • An oil gallery cooling apparatus of an engine is provided to prevent bubble from being generated between oil gallery and cooling water. An oil gallery cooling apparatus of an engine comprises an oil gallery(108) and a heat exchange region(106a). In order to be connected to the water jacket(106) formed inside of the cylinder block(102) of the engine, the oil gallery is equipped in the cylinder block inside. The oil gallery comprises the feed port supplying the oil to the cylinder bore(104) of the engine. The heat exchange region is extended to the oil gallery circumference from the water jacket. In the heat exchange region, the heat exchange occurs between the cooling water within the oil within the oil gallery and water jacket.
    • 提供发动机的油道冷却装置,以防止在油道和冷却水之间产生气泡。 发动机油画廊冷却装置包括油画廊(108)和热交换区(106a)。 为了连接到形成在发动机的气缸体(102)内部的水套(106),在油缸内部装有油路。 油画廊包括将油提供给发动机的气缸孔(104)的进料口。 热交换区域从水套延伸到油库圆周。 在热交换区域中,在油画廊内的油中的冷却水和水套之间发生热交换。
