To further my/our findings, the brass bushing that you/Phil had noted earlier, the one that's pressed in and acts as a volcano-orifice, I noticed that the shaft of the actuator has quite a lot of movement to slop around in there, enough for high pressure air to pass around when the plunger is lifted...

JB That makes sense. The square profile of the lifter would keep the needle straight as it pushes the nylon plunger up.

Sorry, I was having a dyslexic moment: my brain does/sees things backward at times--SIGH! (Mark, I'm sure you know nothing about this ever happening to you Mark and I are both dyslexic...) I hope this image will help someone in the future... JB I think your graphics are great! You certainly are allowed some time for thought and discussion to refine the image of something we can't even see! My hat is off to you, Sir! Now, this thread should become the go-to treatise on the elusive Divair lifty part that millions will refer to as they resurrect their vintage Divair regulators!

That's it! That's what I saw in my vision! Sort of.
Except it was different....
But still!
[I see why you didn't extend the hp body and add the bore that the lifty part rides in, for clarity's sake.
Can I make a request, though, JB? Can you make another diagram by adding a bit that shows the hp seat ending way down by the end, like to the middle the square lifty bit, like it actually is? Me intiendes? If not, lmk.
I think that once the general theme is understood, air by-passing the needle and the square sides, adding in the opacity of the bore and the way the lifty part (are we agreed on the technical term "lifty part"?) rides in the hp body might contribute to understanding.]
What program are you using to make these incredible graphics? My baby brother (he's only 62) uses a program called sketch-up to make nice graphics of the stuff he wants me to build at our cabin. He believes that he's done his part when the diagram is complete. I prefer to fly by the seat of my pants and get him to help with the actual work. But, he makes nice graphics. I tried sketch-up. Way too steep a learning curve.

Adobe Photoshop is my drug of choice Actually, it should be correct where it's resting in the "RED"-stopped side: the plunger is resting on the brass bushing/insert/volcano-orifice: that is the valve seat! I hope I'm understanding you JB

[Yes, but the hp body is truncated in your diagram. The hp body, in the actual reg, ends flush at the plastic boss, and a turret extends up over that to retain the primary lever. The lifty part rides in a bore descending down into the hp body toward the orifice which is say 1/4-3/8 inch down. In your diagram, the hp body ends at the orifice, and the lifty part hangs in space. There's more of the hp body which contains the bore and the lifty part riding in it. What I'm asking for is a representation of the hp body that includes the part of the hp body that contains the lifty part bore and terminates at the plastic boss. Does that make sense?] I wish I could contribute pictures instead of words. I could draw it and take a picture, I suppose. Bah! No tech skills...

Take it apart? No, don't do that. It's fine as is.

No, I mean I need to look at the individual parts so I can draw them somewhat accurately, which is why I take 'em apart... I'm one of those weirdos who will rip anything to pieces just ta see how she workz: I can fix near anything too! Although there was the time my niece came to me, at age two, very sad, "Uncle-Jay fix?" That was my Waterloo: her balloon had popped, and I still haven't lived that one down JB

Dang. I'm starting to sound like my little brother (he's only 6'2"). "OK", he always says, "I've thought about this, figured out what I want, and here's what YOU have to do...."

Wow! That's got to be it!! I think you have captured the valve system perfectly without even being able to see a lot of it! The details are incredible. I don't know how you do it.... You're a talented guy, JB!

I know how he did it...side affect of Dyslexia. Being able to "see" things in our minds, "thinking in pictures", etc. Couple that with a lot of us Dyslexics having a creative/artistic talent,mindset, etc. Mark

Geez Mark, yer totally blowin' it fer me, givin' away my super powers: now everyone's gunna want to be dyslexic Yes, as dyslexics we can do some extraordinary things, but they come with a very high price: dyslexia can be an extremely cruel mistress There are a whole gamut of things, it isn't just reading things backward, and each person has their own unique set of, shall we call them, features?
