摘要： A method and device for controlling at least a first double- acting actuator (1) and a second actuator (2) by means of a first pipe (16) and a second pipe (18) , the two pipes (16, 18) being shared by the two actuators (1, 2) , and both pipes (16, 18) being drained when in the unloaded state, and the working member (4) of the first actuator (1) being brought to be moved in a first direction by pressurizing the first pipe (16) with a relatively high first pressure, and the working member (4) being brought to be moved in a second direction by pressurizing the second pipe (18) with a relatively low second pressure after the first pipe (16) has been unloaded, and the working member (10) of the second actuator (2) being brought to be moved in a first direction by pressurizing the second pipe (18) with a relatively high third pressure.
摘要翻译：一种用于通过第一管（16）和第二管（18）至少控制第一双作用致动器（1）和第二致动器（2）的方法和装置，所述两个管（16,18）是由两个致动器（1,2）共享，并且当处于卸载状态时两个管（16,18）被排出，并且第一致动器（1）的工作构件（4）沿第一方向移动通过以相对高的第一压力对第一管道（16）进行加压，并且通过在第一管道之后以相对较低的第二压力对第二管道（18）进行加压，使第二管道（21）沿第二方向移动 16）已经卸载，并且通过以相对高的第三压力对第二管（18）进行加压，使第二致动器（2）的工作构件（10）沿第一方向移动。

摘要： A pilot-operated check valve (1) including a valve housing (2) and a main slide (4), the main slide (4) being movable between a first and a second position in the valve housing (2), the main slide (4) communicating with at least two main ports (20, 22) in the valve housing (2), and a movable valve body (42), which cooperates with a valve seat (40) in the main slide (4), being arranged to block flow in a first direction between the main ports (20, 22), and to open to flow in an opposite second direction between the main ports (20, 22), and the valve body (42) bearing in an opening manner, possibly via intermediate components (30, 52), against the valve housing (2) when the main slide (6) is in its second position in the valve housing (2), whereby opening to flow in the first direction takes place.
摘要翻译：一个包括阀壳体和主滑板（4）的先导式止回阀（1），主滑动件（4）可在阀壳体（2）中的第一和第二位置之间移动，主滑块（4）与所述阀壳体（2）中的至少两个主端口（20,22）连通，以及与所述主滑动件（4）中的阀座（40）配合的可动阀体（42）布置成阻塞主端口（20,22）之间的第一方向的流动，并且在主端口（20,22）和阀体（42）之间以相反的第二方向打开以开启方式，当主滑动件（6）处于阀壳体（2）中的第二位置时，可能通过中间部件（30,52）抵靠阀壳体（2），由此开始沿第一方向流动。
