    I had a oxygen regulator diaphragm on a cutting torch blow out on me a few years back. It was a full tank also, that was fun. Lol
    It was a good thing I had my brown pants on that day. ๐Ÿ˜ฎ๐Ÿ˜‚

    You don't know how much you've influenced guys like me. Construction workers that need air compressors that do their job well. You have shown me, and in sure many others, how you can make a great compressor work in a way we have never thought of. In the least, I appreate you're information and plan on making a compressor to follow a couple of your advisements. I'll share my project soon

    thats one skoocum prv!! what brand is that?

    One additional failure.. calcification and contaminants creating a blockage that will cause reduced putlet pressure.. ask me how I know ๐Ÿ˜’

    Actually, they are designed to not lose pressure. Its one of the requirements for certain machinery, including air brakes, in case the regulator fails, or the compressor expolodes itself. You need to have pressure to continue operation. Even if you have over pressurization in other systems of a vehicle, those have check valves, with everything designed, in every worst case scenario that still leaves pressure inside the brake circuits, to let you stop once or twice.

    Whyโ€™s this seem like a carburetor

    Thank you! I've always wondered how the diaphragm worked in a regulator… now that I've seen the innards of a regulator it all comes together

    AvE, I have some questions for you regarding US regulators and EU or France regulators. Do you have a way we could chat about this through?

    So the poppet valve is constantly moving?

    Reminds me of an airplane carburetor.. A+B = C+D

    Missed one other mode. Diaphragm tare or displacement. I just had a nice Watts unit spit the seal edge of the diaphragm out of it grove and all ot wanted to do was dump high pressure air out of the ambient pressure side of the diaphragm through the vent holes in the cap. If it had or been like the one you have in the video I think it may of made it longer. What seems to have happened is the diaphragm shrank and pulled out of the grove.

    I think it sealing off the back-flow wasn't because you raised the pressure, I think it's because you left the pressure on long enough for the poppet to seat. When quickly shooting air in and disconnecting the poppet hadn't seated yet so the air shot out. My theory based on what I saw, I've never tested it.

    Can we use this is as a back pressure regulator ???
