The CO2 cartridge in this instance screws into the bottom and the valve attaches to the schraeder. Usually you push this down onto the schraeder which pushes the green part back into the silver body of the valve against the spring, and opens the valve releasing the gas.
But what if you fixed the green part to your barrel/breach and gave the silver valve body a good slap? Well you'd get a short burst of gas released, just like a hammer valve.
I can see it working very well with a bolt action, to recock the hammer, all we'd need to do is work out hammer weight and spring rate (could be adjustable?) to release just the amount of full pressure CO2 we need - because NO, this one doesn't have a regulator.
Is that clear, or should I draw a quick picture?
