Thank you, thank you, thank you. I found a different video that claimed to show how a gas spring worked but ONLY showed applications. I was aware that hydraulic cylinders had different areas on opposite sides of the piston meaning that opening they had more force than closing but did not think about how that would work with a gas spring.
Thank you I finally understand it. I never could figure out why they re-extended on their own if there's a hole through it. Surface area makes total sense!
I was just working on my computing assignment for whole day while sitting on chair playing with my chair's height adjustable spring lever. yeah so good tym to learn about this spring
I've been sitting here for a while trying to figure this out myself... No one seems to answer this question in the videos I've watched. I think it's because the gas is doing whatever it can to reduce the pressure inside to be the same as the pressure outside, which in this case is increasing the internal volume of the cylinder - which is pushing the rod outside of the cylinder. By getting the rod outside of the cylinder, the open internal volume is now increased, lowering the pressure just a little bit. Now, I'm still trying to wrap my head around how the force of the gas resists the extension of the piston... But I think I at least understand how there is force trying to extend it now, even with a hole through the middle.
(I operate a machine that assembles this product). The gas is filled by putting both the completed piston rod and tube in what’s called a filling bell. There’s a nozzle on the bell that lines up with a gap between the tube and top of the piston. An accumulator puts a precise amount of gas in the tube. After that the rod is inserted, the gas filling step is completed and the spring is grooved and closed This is a rough explanation but Hope that helps
Still don't understand. Also don't understand how gas molecules don't constantly escape past the mechanical seals as the piston and the strut slide back and forth.
Heyy. Actually i want to ask you a question. I still can not understand the area difference and it generates force in same pressure? How the piston have different areas lol
@@ik538There is a difference in volume because the piston side has “the piston” which is taking up some of the volume which could’ve been used by the pressurized nitrogen. Therefore net extending force. Which forces the piston out.
That was well explained. Thank you for making this video.
These are such a good invention hats off to whoever invented the gas spring
Thanks for an excellent explanation of how these gas springs work. Very interesting.
Best Technical video on Gas spring , with simple explanation

Thank you Brother Schellenberg!

This young tony.
Didn't thought it's as simple as that!
why won't it stay retracted tho? when pressure on both sides is equal

Do you have any idea for filling nitrogen gas in gas spring

@@monixx9081 Josh I thought these springs had an actuation button on them that allows you to "actuate" the gas spring?
Still don't understand. Also don't understand how gas molecules don't constantly escape past the mechanical seals as the piston and the strut slide back and forth.
They do, but slowly.
Then you need to replace the spring or the whole thing the spring was installed in, i.e. office chair or a very old car.
finally! thank you!
Why nitrogen and not any other gas?
I believe because it’s an inert and non flammable gas and doesn’t react with internal components
Thank you 🙏🏼
Thats awesome
Thank you very much!
Thanks!
Why did you checkmate yourself?

Good video, thank you!
nice vid tbh
I was curious, and this helped.
much appreciated
