    • An apparatus includes a plurality of pneumatic linear actuator modules, a dynamic actuator linkage, and a static actuator linkage. Each of the plurality of pneumatic linear actuator modules includes a static portion and a dynamic portion. The dynamic portion is movable in a linear fashion relative to the static portion. The dynamic actuator linkage connects the dynamic portion of each of the plurality of pneumatic linear actuator modules to a moveable portion of a device. The static actuator linkage connects the static portion of each of the plurality of pneumatic linear actuator modules to an immoveable portion of the device. A number of pneumatic linear actuator modules one less than the plurality of pneumatic linear actuator modules are able to provide linear actuation to the device. Each of the plurality of actuator modules is configured to selectively couple and decouple to the dynamic actuator linkage and the static actuator linkage.

    • A hydraulic controller of construction machinery. A plurality of actuators (4, 7) are actuated by operating operational levers (29a, 30a) while using a main merging/diverting valve (13), provided in an oil path (12) coupling the delivery oil paths (10, 11) of first and second hydraulic pumps, as a flow merging position. Operating condition of the operational lever is judged at an operating condition judging section (41). From among a variety of operation patterns set under that operating condition and stored in a controller (14), an operation pattern matching an actual operation pattern is selected at a pattern collating section. Since delivery pressure of each delivery oil path (10, 11) is high when the load pressure of each actuator (4, 7) is high, the main merging/diverting valve (13) is switched to a flow diverting position when the total delivery pressure exceeds a preset level, and switched to a flow merging position when the total delivery pressure drops below the preset level. Preparation of a troublesome control program is not required in the control. Switching between flow merging and flow diverting can be carried out smoothly with no shock even during work, and an optimal flow distribution is ensured constantly both at the time of flow merging and flow diverting.
    • 工程机械液压控制器。 多个致动器(4,7)通过操作操作杆(29a,30a)被致动,同时使用设置在联接输送油路(10,11)的油路(12)中的主合流/转向阀(13) 的第一和第二液压泵作为流动合并位置。 在操作条件判断部(41)判断操作杆的操作状态。 从在该操作条件下设定并存储在控制器(14)中的各种操作模式中,在模式对照部分选择与实际操作模式相匹配的操作模式。 由于当每个致动器(4,7)的负载压力高时,由于每个输送油路(10,11)的输送压力很高,所以在总输送时,主合流/转向阀(13)被切换到分流位置 压力超过预设值时,当总输送压力低于预设水平时,切换到流合并位置。 在控制中不需要准备麻烦的控制程序。 流动合流与流量分流之间的切换,即使在工作中也可以顺利进行,无冲击,在流动合流和流量分流时也能保证最佳流量分配。

    • A directional valve for controlling an actuator by means of pressurized medium, the directional valve comprising: a spool (4) fitted to move axially inside the directional valve; a first position of the spool (4), in which the spool tends to be set; and a second position of the spool (4), to which the spool can be moved by a pilot control force. In addition to the functions of a directional valve, the directional valve comprises a metering orifice (7) placed in the pressure port (P) or in the first work port (A) or in the second work port (B) or in the tank port (T), and across which a pressure difference is effective. The spool (4) further comprises a second position, to which the spool can be moved by a pilot control force. When the spool (4) is in at least the second position, the directional valve is fitted to generate a compensating force proportional to said pressure difference, to move the spool (4) to compensate for the flow.
