. I think this valve is better. It is easier to do, it opens faster than the usual opener. The master who made this valve has a very good opinion of him What model is that from? I think it's more useful for a multi-shot, while this pumper is intended to dump the whole chamber every time.[/quote] Yes...

200 bar ?

Hi, I was wondering what the best ignition (other than a stun gun) is for spud guns. I generally use 2 nails and the piezoelectric thing from a bbq lighter but I have heard that grill igniters work better. So if anyone knows of any other (under $20 ideally) ignition sources please let me know. http...

Both of you are absolutely right!

The piston valve is very convenient to work in semi-automatic and automatic mode, I tried both options and they are definitely cheaper and simpler than yours.

My impression from the diagram is that the trigger pushes the red part forward against the spring. At some point, it is released, and it moves backwards under spring power, and knocks the valve open.[/quote]
like this?

No, my valve looks like this

great job. But I would advise you to make a QEV valve from plumbing, it is not difficult and it withstands great pressure. My piston valve withstands and operates at 100 atm and it is homemade [youtube][/youtube] On the video in the valve 45 atm, it turns out 3 shots

Hi guys. Yesterday evening I collected just such a toy. I didn’t plan to make one, it turned out))) [youtube][/youtube] A good option for a semi-automatic. I wanted to put a servo on the drummer, but I did not find it.

I think, on temperature and dirt rubber seals quickly deteriorate

I also did it like a pump piston. https://lh3.googleusercontent.com/8Zg5U7QZoy838-OD379sgwP72D28DQTvO3wm4fZNsqtmY98QhoPh53lxcTn2Y-U3lE5ZGNH5mUSfOeb8FUHcJxqf1swLYLzD-w6Y6YV-aA4phizWA_d68cjlnhIize1a6ZoWLS2yZyb7aL3lTHUfgZq-BB7XV5DV4G6pIsDNnpQ-xEIqTHZVpDrueb3Z2Vf2KFQjbCoMeiXjmDfWPuhBWk_9RSG8dWp6s7Xr6jgF...

The valve for tubeless wheels is well suited to the role of a piston, the diameter is just 25 mm.

Do you mean something like this? 17473170.png This thread might be of interest: http://www.spudfiles.com/pneumatic-cannons/topic26478.html#p381298 I know this valve, HUBEN1.
