QEV valve Air Gun | Self Defense Pen

[@rahulreddy7507]

Unfortunately, when you search for "tactical pen diy", instead of something as good as this, you're shown garbage where people are glueing stones and other pieces onto pens. This is actually good quality stuff

[@lunkprab]

I used to build this long time ago. I never know that soldered wire could withstand such pressure! I used epoxy

[@Max-tp8he]

Is epoxy also that tough ?

[@brogannicholas1599]

Incredible my friend. I'd like to see other ways this could be used.

[@ariafathi4694]

Can 2 tyre valves be used, one as entry to charge the cylinder and the other as an exit (propellant) near hammer to shoot projectiles out? (To avoid using all the air at one shot) Or a tyre valve is not good to pump up the pressure in crown fast enough? ❤

[@ariafathi4694]

By the way you're great 👍👍

[@emjerml6647]

the mechanism is confusing

[@dictat0r]

А как она работает я чë тот не понял🤔

[@ChebuplZZa]

Ствол находится в резервуаре. в нем же, за стволом, вставлен поршень(между стенками и поршнем есть небольшой зазор) За поршнем герметично вставлен клапан, через который в ручку заканчивается воздух Через зазор между стенками и поршнем воздух попадает в основную камеру(вокруг ствола) При нажатии на клапан, давление за поршнем понижается, из-за этого он отходит назад. В ствол выходит основной объем воздуха, выталкивая снаряд. Не думаю, что от моего объяснения стало понятнее ;)

[@dictat0r]
