"Constant Force" means that force does not change with stroke as opposed to a normal gas spring that has more and more force as it is compressed.
That is why reidtool specifies the force of their "fixed force" springs at their extended length (theie P1* note)...because the force increases as it is compressed.
As we know of gas: PV=NRT...so as the volume decreases, the pressure increases->greater force

I'm pretty sure that gas springs are constant force. That's the whole point of them. Fixed force means that you cannot adjust the pressure. You buy a 30lb spring and that is what you get. The adjustable allows you to (one time) remove pressure down till you get it right. If you go too far, you are out of luck.
