    Spool valve idea I came up with...

    Alright, every once in a while I get an idea and I don't think of all the reasons it would not work. So now, I want AO to tell me what is wrong with my new idea. Here is a picture of the valve.

    Here is an explanation I am sure no one will understand..

    Alright, parts list - Left to Right, Big Blue Blob is the paintball. The big orange and yellow thing is the bolt. The orange parts is the outside of it, and then the orange part in the middle of that is a little cut out. There is a spring around the bolt. The little black dots are just empty space. To the right of that, there is a big purple thing, and inside of that there is blue stuff. The blue stuff is air, and the purple thing is what is sealing it. Note that at the very left of these 2 things there are two white holes (top and bottom) Then you will see more right from that, there are 2 virtually identical holes, and red rectangles, these are air ports that push things forward or backward.

    Function
    Alright, this picture is showing a resting period, What would happen first is on the top right, port (labelled 1) will fill the space with air (red part) to push the assembly forward. As this happens, the little black dotted area will be consumed, and the little arms would push the bolt forward. After you keep pushing it, the little wholes in the blue area will pass over the little slot in the bolt. Thus, air sends the ball flying. Once this happens, the assembly will be so far forward that the #2 port will have access to push it's air supply out, so it starts pushing and then the assembly will go backwards, and the spring around the bolt will push it far enough for another ball to fall in.

    Thats a lot like how the shocker and ion work though..

    They are different though, and i think yours is pretty smart. The only thing i dont like about it is how the air enters the back of the bolt. I *think that if the air isnt entered evenly it wont be as accurate.

      Yeah, I realize it is alot like those, and that is why my "butt" will get sued but then again, aren't all spool valve's extremely comparable? I remade some stuff, after thinking a bit..


      There is a crown sorta, so alot stronger than the arms. There is a "qev" type thing to take out access air, and well, I am thinking of other things.

        Well one thing, you kinda need to make everything simmetrical. Since its round, all these grooves and stuff would have to be centered and would go all the way around the core.

        I really am confused with your drawing, it doesnt do much justice...

          I understand the pictures completly, I have one question though. On the 2nd port, you said once the bolt gets pushed all the way forward that port 2 will be opened up, is this going to be a timed thing or will there be a slot on the bolt to give it just enough air to start pushing it backwards? From the looks at it, I dont think port 2 will do much good. Perhaps if you moved the port forward to the end of the red part on the bolt, then when the air is released all of the air will force the bolt back until the bolt closes the opening and then the spring can take over. It does look like it would be a fun project, even if it does resemble the other spool valves.

            Alright, I have added some new features..



            Basically Port #1 now has ALOT more air pressure, and will push the purple thing as well as fill it.

              it seems that with a few modifications to your piston (purple thing) you could eliminate the bolt. you might consider making this a trapdoor type marker. the one main issue i see with the design is the impact of the piston on the bolt. it seems like there is a lot of potential for wear.

              very cool to see someone expanding on/ tinkering with the spool valve design. keep it up.
