They are actually flow regulators, but their behaviour is piloted by the plenum (or whatever you have between your reg and your tp). The reg stop sending air once the pressure is balanced. You can clearly see that in guns that have a bleeding screw, such as a RTI Priest/Prophet or others. Once you start bleeding your gun, the reg keep sending air continuously. That's cause the reg work on pressure, not on volume

A regulator is responsible for providing a stable, repeatable pressure. It must flow air in order to perform this function but it is confusing to conceptualize it as "flow regulator".

In a PCP, flow is most often a topic of interest for the firing cycle rather than the plenum refill cycle...though the latter will occasionally come up. For the most part, porting is what dictates flow.

That question is like asking why a blower on a cars engine is not called a compressor since that is actually what it is doing.
It does not blow anything.
And a Turbo Charger doesn't charge anything. It should be called a turbo compressor only because a turbine is compressing the air.

Thanks for the replies. I am asking the following, not to argue but to try and understand better.


"That's cause the reg work on pressure, not on volume" So if I understand you correctly, you say that it is actually flow regulator but act as a pressure regulator. A flow regulator will mainly work on volume, right?

"The reg stop sending air once the pressure is balanced." Is that not the working of a pressure regulator? It close when it reached the set pressure even if there is now flow. My logic say that, with a flow regulator, if the flow gets less, it will open more to give more flow. Am I wrong?



"It must flow air in order to perform this function" Yes that is true, until it reach the pressure then it close down so then there is no more flow.
" it is confusing to conceptualize it as "flow regulator." That is my problem.

The flow through the barrel is dictated by the valve and the transfer port, fueled by the existing pressure in the plenum, not air coming through the regulator during the firing cycle. Right?

Again, I am just trying to understand. Thanks.

Correct ... the regulator DOES NOT supply air as the shot is happening, it only replaces whats been used within the plenum after the shot cycle has happened.
