    • The present invention provides a cooling water circulating apparatus capable of securing a required flow rate of cooling water without increasing the heads of water pumps. The apparatus includes a first water pump which has a first supply port for supplying the cooling water into the first water pump, the cooling water for flowing through the interior of an engine, and a first discharge port for discharging the supplied cooling water from the first water pump to the engine again, and which is directly connected to and rotated with a cam shaft of the engine. A control mechanism is adapted to cut off a flow of the cooling water, which is directed from a radiator to the first supply port, when the temperature of the cooling water is not higher than a predetermined level, and operatively connect the radiator and first supply port with each other when the temperature of the cooling water is higher than the predetermined level. A second water pump includes a second supply port for supplying the cooling water from the second water pump to flow through the interior of the engine, and a second discharge port for discharging the supplied cooling water from the second water pump to the supply port of the first water pump. The second water pump is not rotated when the temperature of the cooling water is not higher than a predetermined level, and is electrically rotated when the temperature of the cooling water is higher than the predetermined level.
    • 本发明提供一种冷却水循环装置,其能够在不增加水泵头的情况下确保所需的冷却水流量。 该装置包括第一水泵,其具有用于将冷却水供应到第一水泵中的第一供应口,用于流过发动机内部的冷却水和用于从第一水泵排出所供应的冷却水的第一排出口 再次将水泵送入发动机,并直接与发动机的凸轮轴连接并与其一起旋转。 当冷却水的温度不高于预定水平时,控制机构适于切断从散热器引导到第一供应口的冷却水的流动,​​并可操作地连接散热器和第一供应 当冷却水的温度高于预定水平时,彼此相连。 第二水泵包括用于从第二水泵供应冷却水流过发动机内部的第二供给口,以及用于将供给的冷却水从第二水泵排出到第二供水口的供给口的第二排出口 第一水泵。 当冷却水的温度不高于预定水平时,第二水泵不旋转,并且当冷却水的温度高于预定水平时,第二水泵电旋转。

    • In a vehicular lamp, a front lens is mechanically fastened to a lamp body by a fastening device formed astride the boundary between the seal groove-defining wall and the front lens during insertion of a seal leg portion of the front lens into a seal groove with a sealant provided therein. The fastening device includes stopping protrusions provided on the seal groove-defining wall of the lamp body and tongue-shaped elastic pieces that are provided on the seal leg portion and have openings. As the seal leg portion is inserted into the seal groove to mount the front lens to the lamp body, the tongue-shaped elastic pieces are pressed against the stopping protrusions and thereby elastically deformed outward. The stopping protrusions thereby smoothly engage with the openings so that the seal leg portion will not fall apart from the seal groove, without requiring a plate spring.
    • 在车灯中,通过紧固装置将前透镜机械地紧固到灯体上,所述紧固装置在将前透镜的密封腿部分插入到密封槽中的过程中跨过密封槽限定壁和前透镜之间的边界, 设置在其中的密封剂。 紧固装置包括设置在灯体的密封槽限定壁上的止动突起和设置在密封腿部上并具有开口的舌形弹性片。 当密封腿部插入到密封槽中以将前透镜安装到灯体时,舌形弹性片被压靠在止动突起上,从而向外弹性变形。 因此,止动突起因此与开口平滑地接合,使得密封腿部分不会从密封槽脱落,而不需要板簧。
