    • It is an object of the present invention to provide a control valve which can reduce the number of external lines connected to a hydraulic remote control valve. A control valve 1 for controlling hydraulic cylinders 2,2' is provided, in one 26 of spool covers, with fluid passages 27,27', a shuttle valve 28 for selecting higher one of pilot pressures to be transmitted to these fluid passages 27,27', and a fluid passage 29 for transmitting the pressure selected by the shuttle valve 28. The fluid passages 27,27' are in communication with pressure fluid ports 25,25' as connection ports for pilot lines 24a,24c. The control valve 1 is also provided, in the other spool cover 32, with fluid passages 33,33', a shuttle valve 34 for selecting higher one of pilot pressures to be transmitted to these fluid passages 33,33', and a fluid passage 35 for transmitting the pressure selected by the shuttle valve 34. The fluid passages 33,33' are in communication with pressure fluid ports 31,31' as connection ports for pilot lines 24b,24d.
    • 本发明的一个目的是提供一种控制阀,其能够减少连接到液压遥控阀的外部管线的数量。 用于控制液压缸2,2'的控制阀1在一个滑阀盖26中设置有流体通道27,27',用于选择较高的一个导向压力的往复阀28传递到这些流体通道27, 27'和用于传递由梭阀28选择的压力的流体通道29.流体通道27,27'与作为用于先导管线24a,24c的连接端口的压力流体端口25,25'连通。 控制阀1在另一个阀芯盖32中还设置有流体通道33,33',用于选择较高的一个导向压力的往复阀34以传递到这些流体通道33,33',以及流体通道 35,用于传送由往复阀34选择的压力。流体通道33,33'与作为用于控制线路24b,24d的连接端口的压力流体端口31,31'连通。 <图像>
