可控气弹簧：

    可控气弹簧在整个行程的任何位置都可以锁定。主要是通过控制器（手柄或者拉线）达到效果。也可通过活塞杆的伸缩来实现。当用控制器调整在理想位置时停止，阀门会独立的关闭，活塞杆会锁定在所要求的位置。当锁定发生时，能实现锁定。但是如果超过了锁定力，锁定功能将不再有效。

lockable gas springs can be locked anywhere along the complete stroke.by pushing the release pin,the piston valve opens allowing gas or oil to flow through the piston and the piston rod extends or can be pushed in.when the release pin is no longer being pushed,the valve closes independently and the piston rod is locked in the desired position.when the locking force is exceeded, the locking function in no longer given.
