you did not get me, I was not saying the reg had a fixed mp but only that if we fixed it's mp it would work as a kiss

Ops, sorry, i misunderstud.

the discussion was about the submatix, I don't know the details of the voyager certification

Check it, it is the same certifier of the voyager that issued an "anomalous" certification to he submatix. Bth are isuued by a "non notified body", so both seems not regular.

Quote:

some still think that when the flow rate resch a sonic speed the flow can't increase regardless of the pressure,

Most of the voyager users think this, beacuse they have been instructed in this way.

Quote:

but it is not true of course the flow get's higher getting deeper...this the reason why we use fixed MP regulators (((-:

As i told you i had to test a voyager needle valve with manometers and flowmeters to try to convince a friend.

please send me the articles.

ok, let me see if i am able to attach at the end of the message.

A bientot (pas d'accents sur mon ordonnateur).

you are right.
I have two friends who bought the first version of the Voyager 5 years ago (or even more).
They have been told that this needle valve gives a constant molecular flowrate or something like that

Anyway, you can run it like a Pelagian.
If I understood correctly, with a non fixed IP regulator, the oxygen flowrate will increase by 1 % every meter.
So you need to adjust the flowrate at the surface to match your metabolic consumption at the maximum depth.
And between the surface and this max depth, you will manually add oxygen more often that on a real KISS system.

Yes every thing is possible tuning the mp, the flow rate to the max depth... but I prefer to kepp it simple stupid, I splach and press the button sometime....

thank for making it clearer for me,
so the oxygen flow must be controlled by the diver during the dive , the diver must tune the flow rate on the fly !!! whaouw !!!
and the diluant is added via an adv rigth ?
it must be difficult to fly...I mean more difficult then a kiss.
did you try it ?

Hi Jean-michel,

For your info Ive seen Pascal Bernabé who was using a voyager 1 two years ago for a push dive up to 180 m and he explained that at the deepest part of the dive he had to add dil continualy for lowering the PO2...

After that a usual joke was: Pascal is a great diver, he even survived to the voyager, and the voyager is not such a bad rebreather because he survived to pascal

Hi Marc,
this clear now....they don't explain the working principle of this breather in their site cause it does not work , I mean the mass flow rate is not constant when the MP goes up
I thought they had invented amiraculous system but.....no (((-:
