    • A flow control system for a hydraulic pump of a construction machine that can variably control a discharge flow rate of the hydraulic pump in accordance with load pressure generated by a hydraulic actuator. According to the system, the discharge pressure of the hydraulic pump and the operation rate of the operation lever for the hydraulic actuators is detected, and standard load pressures of the respective hydraulic actuators are set. If the discharge pressure of the hydraulic pump is higher than preset load pressures of the hydraulic actuators, the discharge flow rate of the hydraulic pump is reduced in proportion to the operation rate in accordance with degrees of loads generated by the hydraulic actuators. If the discharge pressure of the hydraulic pump is lower than the standard load pressures of the hydraulic actuators, the discharge flow rate of the hydraulic pump is controlled in proportion to the operation rate.
    • 一种用于建筑机械的液压泵的流量控制系统,其可以根据由液压致动器产生的负载压力可变地控制液压泵的排出流量。 根据该系统,检测液压泵的排出压力和液压致动器的操作杆的操作速度,并且设定各个液压致动器的标准负载压力。 如果液压泵的排出压力高于液压致动器的预设负载压力,则液压泵的排出流量与根据液压致动器产生的负载的程度与运行速率成比例地减小。 如果液压泵的排出压力低于液压致动器的标准负荷压力,则液压泵的排出流量与操作速率成比例地控制。

    • A connector for a Low Profile (LP) fuse which has an increased fixing force, so as to prevent a secured LP fuse from being separated by external forces, such as vibration of a vehicle, etc. The connector for a Low Profile (LP) fuse includes a body, a rear member, and a pair of supporting arms. The body is adapted for insertion into a body receiving passageway of a fuse box. The body includes a lower end electrically connected to an electric wire. The rear member extends from the body into the body receiving passageway, while the pair of supporting members are bent from opposite sides of the rear member. The pair of supporting members extend parallel to each other.
    • 一种用于小型(LP)保险丝的连接器,其具有增加的固定力,以便防止固定的LP保险丝被诸如车辆的振动等外力所分离。用于低轮廓(LP) 保险丝包括主体,后部构件和一对支撑臂。 本体适于插入保险丝盒的身体接收通道中。 主体包括电连接到电线的下端。 后部构件从主体延伸到主体接收通道中,而一对支撑构件从后部构件的相对侧弯曲。 一对支撑构件彼此平行地延伸。
