Adjustable gas spring

  1. Jun 23, 2014 #1
    Hey,

    Has anyone heard of a gas spring that could be adjusted in mid operation? The gas could be released from the gas spring to decrease the pressure inside and alternatively gas could be injected by a compressor to increase the pressure in gas spring.

    I have only found gas springs, in which the gas can be released. And this is typically achieved by manually releasing the gas. But I am looking a gas spring system that could be modified in an automated fashion.

    Thanks!

    Consider a typical linear actuator, (pneumatic cylinder), controlled by a directional valve, (maybe solenoid operated), with compressed gas from a pressure reservoir.

    That appears to be what you are considering.

    Such a system will be inefficient as only full pressure and exhaust pressure are available.
