Its very obscure, probably on purpose.
How I read it is that they have invented a marker which does not need a spring to propell the hammer into the valve.
I know most cupseal type valves contain a spring but they describe other guns as spring loaded, that must mean the spring is compressed to store energy, unlike the valves in most paintball markers today where the spring is there to keep the valve closed.
The only markers which can be described as spring loaded are cockers and blowbacks.
So they have a gun which is not spring loaded(in other words its not a cocker or a blowback, theres prolly others I have missed), that uses an electropneumatic flow distribution device to cock and fire the gun. I can name about 20 peices of prior art right now!!!
