In this topic, i was told that i needed an air hole to get a pressure reference , but i found a pcp link that tells that there is no need of any kind of air hole, just a spring and o-rings.

Who is right?

Have you seen this presentation?

Also, since you're not using particularly high pressure, why not just buy one? I still happen to have these available

sorry demon
if you understand how regulator works .....

in the other thread the reg2 paint shows the reg with hole
but u can use the same design without hole if you can make a absolutly tight seal to the sprimg area
a tiny leak and a pressure uprise in the spring area ---> outputpressure wil change
also you can use a air spring insteat of the normal steelspring

what you need is an absolut constant force from spring and this include the pressure

edit why not a hole? 1mm is ok
let show the other specs of your design please what is ID of
the chamber

Also, since you're not using particularly high pressure, why not just buy one? I still happen to have these available

The trick here is that it as to fit in a cooper pipe.

But its alright, i get what is the disadvantage of not using an air equalising hole.

Thank for your support
