Hello. Today made automatic rammer bullets in the barrel. The system in airsoft drives. The design is not completed yet, much work remains. [youtube][/youtube]

[youtube][/youtube] so I pumped pump 45 bar.

Hello. I started doing a pneumatic gun. I use the pop-off valve, a self-made. The valve is stable, you can do "brrrrrrrr" and can be "Dhaka, Dhaka, Dhaka"))) [youtube][/youtube]

Hello. I want to show you my new gun. Its main feature is that I can change the trunks changed caliber. I can shoot arrows. The gun I used the piston valve, the reservoir tank welding. The pressure of 40 bar use. [youtube][/youtube]

I did a few rounds of air, and made for them a gun. The air cartridges I pumped up to 40 bar. Used barrel of 15 mm caliber.

Shooting from the air cartridge. The pressure of 40 bar in it. [youtube][/youtube]
Make it very simple.[youtube][/youtube]

Anybody got any ideas on a fully pneumatic powered semi automatic bolt action set up. I'm thinking pulling the trigger switches a pilot valve to send air down the barrel, pulling the trigger fully in, shuts of that air and triggers the reload cylinder ( bolt action ) so a secondary actuater on the ...

There is. The rubber ring. The barrel is pressed against it and very tight.

So her drummer works. weak punch opens the valve. [youtube][/youtube]

Woah, so it's a reversed hammer valve piloted piston valve. Definitely the first one I ever saw. Can't tell how well it works from the video but well done. I always use hammer valve piloted piston valve. It is very convenient. Air Saving energy and good power. [youtube]https://youtu.be/c1azUT5fzhU[...

Hello again. I made a new valve and want to show you. Some of you have been doing something similar? I plan to use it for a pneumatic machine, you only need to put a spring. Iron part can still work as a projectile in the barrel rammer. Piston valve without waste))) [youtube]https://youtu.be/ipepvvG...

[youtube][/youtube]Thank you very much for your answer. I thought it was a new valve. I have already done so.

Many thanks. Which valve is shown in a photo of your profile? It is a variant of the piston of the valve? Do you have information on this valve?

[youtube][/youtube] So I shake pump 50 bar to their guns. It is easy to make and easy to fix. I use this pump for more than six months, everything works.

[youtube]https://youtu.be/IUrvcYkchU4[/youtube] Probably the last video with this rifle. Looking at the details of the new project. The video rifle injected to 40 bar. bullet speed of 190 m \ s, measured the ballistic pendulum. I wanted to attach a store on 5 charges, but did not. I did not want to ...
