After 4 tins of JSB pellets through my Artemis PR900w the time has come to regulate the rifle.
Owning the cheapest PCP on the market says a few things, one of them is my budget is small, very small.
So when it comes to regulating the rifle, there isn't much of a choice other than building my own one.
I did a lot of research on o-ring design and regulators and the Robert Lane videos on Youtube was very helpful.
When I was happy with my concept, I got the springs and tweaked the design around them.
Here is the 2 springs I got.
My calculations showed that I needed around 600N of Spring force to acquire an average regulated pressure of 9Mpa or 90Bar over the 200Bar-80Bar fill pressure range.
so I got a 350N/mm and a 270N/mm spring of equal length and OD.
Here is a section photo of the design:
