Invert Mini Regulator Discussion

[trevorjk]

ok so i started a thread here, but not much along the lines of productive talk

http://www.pbnation.com/showthread.php?t=2609470

anywho, people say that it would be FAR to difficult and costly to produce an ON/OFF regulator with a purge for the mini.

however, when ever anyone says that it would be nearly impossible or that it would add to much room to the back of the regulator. when they say this i always point them to the centerflag dynaflow




as you can see from the pictures it is a very small tank regulator and it has an on/off with a purge system BEFORE the regulator part of of the reg. there for shutting air off before the air gets to the reg. so basically to make the dynaflow work great on a mini, all you would need is a low pressure spring pack for better consistency around 150-200 psi, and instead of a tank mount it would need a tank ASA. also, take the tank pressure gauge off and run your air source into the gun there, and you could plug the fill nipple port. so for the people that say it would be to difficult, theres a perfect example of how easy it can be. and this regulator compared insize with the invert mini reg is almost identical insize (from tip of reg to back of tank mount/asa)

now for people that say to get the Smart Parts ON/OFF with out purge, or the new designs with purge. your point is valid, but there IS a market for a one piece design for such a product.

so what do you better educated people here on AO think? if a company made a run of 100-200 and sold for around $125 would you buy one? think its feasible? opinions?

and no, i do not have the means or money to make a run of these, just figured an educated discussion on such a product might hopefully get some one to do something

Nice but I'd rather have a user servicable rebuildable reg for the mini than an on/off.

Doesnt anyone know how to degas a marker without an on/off anymore??

Edit** If you are talking about totally replacing the stock mini reg then your idea would be a winner ***

There's a slight problem with your choice of regulator. The dynaflow's pressure goes up as the tank gets empty. Pefect for a mag but if that blows past 200 psi you're gonna need a new noid.

thats why i noted a new low pressure spring spack

Nice idea, but centerflag had already made a solution for the mini's problem. I'm just glad I have a working 420 sv for my mini. Now I'm just upset that centerflags gone.

I'd prefer somthing along the lines of a macdev conquest or pushbutton legionair. The conquest is an adjustable output tank(250-600 or so) the legionair is a fixed output pressure.

Both are on/off tanks and I know the conquests purges(not sure of the legionair)

I do not think there is a single reg out there that can reliably put out a stable pressure with an input ranging from 4500psi to 200psi (any tank reg). Dual regulation at least divides the primary variance by a large amount.. typically by 1/50. When 10-20 psi significantly affects a markers velocity (most spool valve guns), I will take dual regs any day.

You still will have 2 regulators, but the second one need's an on/off in the case of the mini cus it also servs as the ASA.

Ah ok. I thought Trevor was trying to say build a tank reg that serves the purpose of the only reg on the Mini.

Add an on/off pushpin to a tank with the Myth reg guts and have a "normal" length preset screw in tank for the mini, with vent.

The Mini isn't a spool, it's a Pressure Controlled Poppet.
I see where you're going, though. Why not just put an on/off in the grip frame? Put it in the left or right side for lefties or righties. Wouldn't be too hard, all you would have to do is replace the little rod that carries air through it with a ball valve of the right size and such.

well the reason i would want a on/off before the regulator is so that i can shut the air off and bleed most of the air and take 1 maybe 2 clearing shots (as is with pretty much any gun on the market) now if i were to go the route that you would suggest, the reg would still be pressurized.

yes i was refering to the dnyaflow regulator as a means to show that it is VERY possible to have a regulator with an ON/OFF with purge BEFORE the regulator on the mini. (just turn the dynaflow into an asa regulator)

im still trying to figure out after a year and a half why no one has made a run of mini regulators with an on/off before the reg. kind of boggles my mind. but there are plenty of bolts that reduce weight by 6 grams!!!!!

Ehh.. Lets call Simon in here and re-hash the year old debate on if the Mini is a spool or a poppet. I refer to it as a spool here due to the parameter of increased pressure directly results in increased velocity. Poppets (Autotockers, spyders, etc) can be tuned where the pressure input results in a plateaued velocity increase, and can actually have an inverted effect on velocity. This due to a constant hammer/spring force pushing a valve surface area into the pressure chamber, "popping" it open. But I think we get the original point, which turns out is mute, since I mis-understood the original post.

The main need for the Mini is to be able to vent the pressure on the tank ASA threads, thus easing unscrewing of the tank and not gauling up the tank threads over time.

I agree that the mini is more spool than popit.

KEE/Invert is not AGD and they won't make the gun 100% perfect right out of the box. I suspect that there's probably going to be a new version of the mini that will solve the minor problems the mini has and there's probably an on/off reg already designed by their R&D team. It'll probably be on the next iteration of the mini and it's probably why we're not seeing Invert come out with an aftermarket product. We'll see it when Invert decides to release a major new version of the mini.
