Is it possible to have a working marker without a poppet style valve? I came up with this design and I want to know what you think of it. Basically, the bolt acts as the valve. It moves back and forth controlling the flow of air down the barrel while at the same time loading and sealing the breach. I don't know enough about fluid dynamics to make statements about how well this would work, but it seems like a valid theory to me.

Yes, that would work. You would need some sort of recocking mechanism.
PS: Of course a gun can work sans poppit valve. Automags dont have one. The world is not cockers and spyders.Originally posted by AGD

The joys are when you make it work well.
The struggles are when they want it to be a different color

Holy crap!
Add a ram to move the bolt back and forth and you just invented a spool valve!
Oh... wait... nevermind.

idea
Hunter, a few similar things have been done like this, but your idea definitely shows some creativity and is definitely something you could play with. Good work, ignore the critics but don't be afraid to listen to what the say and let it help you advance your ideas.Feedback: http://www.automags.org/forums/showt...hreadid=105565

If I'm not mistaken, the matrix stores the air for firing the paintball in a chamber behind the bolt, not under it. As for the claim about this design being a spool valve, I agree with you 100 percent. It is exactly a spool valve. However, I am unaware of any marker that uses the bolt as the spool piston. That is why I thought this was a unique design. I am not overly knowledgible of the operations of the matrix. So if I am mistaken as to the firing sequence of the gun, I appologize. Feel free to correct me and add to mine and the communities general knowledge.----A.H.----Comment

I forgot to ask one thing...
When the bolt cycles, the third o-ring back(assuming you can see the picture I attached) has to pass back and forth over the air inlet. I figure the inlet would be running around 150 psi or higher. Would this motion destroy the o-ring as the gas moves around it?----A.H.----Comment

no
I'd like to say no it wouldn't, but I'd get a second opinion on that. I think referring to how an autococker bolt cycles would be beneficial, it also needs orings to seal the airflow and one does pass over the inlet hole, I think general friction would be the concern not being exposed to the air pressure.
Now my question is, what do you plan on using to make the bolt move?Feedback: http://www.automags.org/forums/showt...hreadid=105565

The difference is that an autococker has a seperate valve. The o-ring in question is past the hole going to the top tube when air pressure is applied. No air hits the o-ring until the hammer opens the valve in the lower chamber of the cocker. The bolt would move back and forth using low pressure air and a spring. I was thinking a blow forward design to reduce air usage.----A.H.----Comment

can a solenoid provide enough air flow to shoot a paintball? I was wondering what if you just took 2 solenoids 1 for the bolt and 1 for acting as a valve to shoot the paintball?
You better watch yo' self B!Comment

I'm not sure whether or not a solenoid powered spool valve has the flow rate to shoot a paintball. The air passages and valve assembly in a solenoid spool valve are very small. I don't think you could get enough volume of air through them to make it work effectively. Also, the standard solenoid spool valve used in most markers will start to lose seals around 220 psi. Since it has to use a low air pressure and has a very small volume, I would say it could not shoot a paintball. As for the dual solenoid marker, yes, you can easily use two solenoids. In fact, this is the design used in the original shocker. However, their are two problems I see for a double solenoid marker. 1: the space required for two solenoids and the accompanying air passages makes for a larger gun body. 2: Solenoids consume a certain volume of air, having two would consume more, lowering your efficiency. As you may know, these were two of the complaints of the original shocker design. The other style of marker that uses two solenoids is the electro cocker conversion. It uses one solenoid to release the hammer(providing air for the shot) and another solenoid spool valve for moving the bolt back and forth.----A.H.----Comment

could you use a use a regular push pull soleniod and eletricaly move the bolt back and forth

I've had exactly the same idea.
But, you're missing a way to control how much air is dumped and an o-ring or two.
My idea isn't missing that at all.
