It works in exactly the same way as any blowgun does - what most people don't seem to realise is remove the "trigger" and add a spring-loaded weight to a blowgun and you have a de facto hammer valve ;)

It´s a shame you have not referred to my 35 bar repeater design yet jack!! :cry:
Maybe you haven´t read it yet...
I used a bucketload of epoxy for crying out loud!


Anyway..
Jack is right.A blowgun is essentially a hammer valve.
That's why I used only the essential bit of it to actuate a QEV.
This way I got both the power and the higher number of shots.

A hammer valve alone would be even more air-efficient.
This hammer valve thing seems to be the latest rage..
These things come in waves, so it seems.
We have seen a wave of MMG's, inline bbmg's a whole bunch of 2"pistons being made, a couple of guys, including me and Jack, tring a pressure activated full auto valve... and now everybody is on to hammervalves..

I wonder what's next...

You can tell how awesome a cannon is by the pressure used.

Not much different from other PCPs, only it's an inline valve so much moreefficient, hence the high power that the stealth-talon-condor family is capable of - all explained in detail here ;)
