气弹簧的类别

一、           支撑气弹簧 Lift gas spring

也叫自由型气弹簧、支撑杆，是应用最为广泛的气弹簧。它主要起支撑作用，只有最短、最长两个位置，在行程中无法自行停止。在机械设备、家具等领域应用最为广泛。

Lift gas spring is also named kingh thead which is the most popular and widely used gas spring.It's main purpose is to support,it has only two conditions:the shortest and longest,it can not auto stop in a stroke,It's longest when free and short when pressed by force and can evenreach the shortest.

二、可控气弹簧Lockable gas spring

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.

三、阻尼器 Damper

阻尼器特点通过改变尺寸来减小惯性和降低速度，其阻力随着运行的速度而改变。可以对相连的机构的速度起明显的阻尼作用。

Damper are used as safety and function elements in order to damp speed and to slow down masses.

四、拉力气弹簧Gas traction springs

又叫牵引型气弹簧。用内部的活塞杆实现基本的定位。是一种特殊的气弹簧:支撑气弹簧在自由状态的时候都处在最长的位置，在受到外力后是从最长的位置向最短的位置运动，而牵引式气弹簧的自由状态在最短的位置，受到牵引时从最短处向最长处运行。牵引式气弹簧中也有相应的自由型、自锁型等。

It’s a special gas spring,the basic position of gas traction springs is with inserted piston rod. On usually situation,it’s short (standard situation).When giving pulling force, it will moves to the longest position.When release force, it will retracts to the shortest position.
