RE: [PSUBS-MAILIST] Emile's Overpressure Valve



Hey Jay,
 
I knew that,   really I did I promise. ;)'   I was mostly interesting in how it was spring loaded, then I'd reverse the side it seals on to be basically like what Vance described for venting the MBT's, but larger.

Brent,

The images of the valve on the inflatable pontoon is the fill valve, not the relief valve.  It works in a similar manor but is reversed in this case.

Emile your SS overpressure valve you have a picture of on your site is very interesting. Do you have any more pictures of it when taken apart? I would like to see the seal on it if you don't mind.  It looks like a larger metal version of the valve I found on my friends inflatable pontoon boat.  I was thinking of an idea for making a piston vent valve for my MBT's a couple of days ago and when I got to my friends place that same day I found this valve that worked much like I was thinking, except the valve would seal in reverse of what it does, just like Vance's mushroom valves. Here are some pictures of that valve on the pontoon boat.

That valves patent number is 4478587 and you can see it's details and drawings here.

I found this valve for inflatable boats which I think show a number of the basic details Vance described for his mushroom vents. It is patent number 4927397 and you can see it's details and drawings here.

One more for comparison.

Hi,

 

The plan of my earlier mentioned project “Drebbel” chanced a little.

The owner of the divebase at lake Hemmoor wanted to have a sub.

Specs are pretty close to my earlier plans so Carsten and I made a agreement with him. We design and produce parts and the sub will be sold as a building kit.

http://www.airesearch.nl/index_bestanden/Page424.htm  click on “kreidesseesub” I hope to inspire people with the picture log!

We hope to launch in summer 2009.

 

Best regards, Emile van Essen
