    Okay, where to start?

    The piston might slow down the hammer action, but the system needs a separate lpr supply or the air from the valve release will enter the piston, start charging it, and the air from the vale would vent totally down the barrel, hence venting the piston, unless you use a check valve.

    I am not to sure about thoughts on the 3-way valve for the 'Cocker. I looks like it could breed some serious binding problems in from not being unbalanced (yup, unbalanced) enough to run the way you want it to. Also, what is the deal with the bolt/push action? Unless you use a bolt design like the one I showed you, the bolt closing before the air gets outta the valve is NOT going to work. Thats why you don't see any designs like that. The design is then blowforwad, and blow forward is BOLT only. Now look at the ATS and Vector designs, using 4-ways connected to a ram, activated by the hammer. That gives you the action for full auto, plus the light connections between bolt and hammer. The Sterling Pump is a good staring point for a couple of your ideas. It has a great hammer action, and the bolt can be separate or connected for testing. Dam good gun also. I need to get me one.

    Pass on more.

    Look into the Sov's bolt, and the Shockers. I think a good burst of air a similiar system would get it going well. Look good and hard at areas that have pressure on them In a bolt, look at the surface area, and mutiply it my the pressure used. Look a bit into fluid/volume/pressure ratios, and realize, the what numbers you are looking for dealing with the pressure/velocity have to include volume, so you would be looking for Energy used in a system and NOT just pressure.

    I will go off on this later

      I get ya.
      I am pretty much done with that design unless the other guy can explain how this is all gonna tie together. No I am focusing on using a piston to power some things... And what do you think about this:

      Some guns (electronic) use solenoids to activate the valves.
      Now, valves are normally setup like the following. Gas inlet. actual valve (rod with hole in it that gets pushed so the air ga flow through the hole), and an outlet. The rod with the hole (forget tech term) is pushed by what is normally a vlave pin. What if.. teh rod w/ hole and pin were replaced by a piston that had the rod atttached. This would be powered by some sorta small pressure on/off valve i tneh trigger that would take air from a onboard regulator. This would eliminate the need for a hammer to hit the valve pin. Pull the trigger, sends low pressure gas to piston, piston (with hole in the rod on the piston) opens valve, witch sends hgih pressure air straight from reg out gun. The sear to activate toe on/off for the piston would haev to be liek that of the 98, one click, single shot, or the user could jsut hodl the vavle open. I have no idea how this would tie itno the rest of the gun, but its just an idea. Maybe thit could be used on boltless guns, where not only does the piston open the valve, but it closes the 'trap door'.

      Josh, I would really like to talk with you more about this kinda thing. Head up to the AO IRC caht now and then, I'm almost always there. And if I said "ram" anywhere in this post I meant piston.

        WEll, now you are talking my language!

        I am short for time, so here is a Cocker,BM2K, whatever poppet emulator type of valve. A Poppet Emulating Valve (PEV)is a valve that copys the action of a hammer/poppet, but doesn't have either. The Ram opening a piston is how a Paradox gun runs. The ram shaft runs through the valve, and is connected directly to the seal for the poppet valve.

        Here is one build to be ran by a 4-way switch.

          that is a normal closed position, and this one is open,

          Sorry for the size

            YES! That is exactly what I was talking about! The reason I have avoided that design all this teim is becuase it would require more advanced pnuematics, and I was going for a pure bread maechanical, so, I avoided it. But that has been sitting in my mind for years.. just begging to be put into one of my gun deigns.

            So I see you use 3D Studio? Or is that some other modeler? I am very fluent in MAX, and that is where I work on the animation prospects of my deisgns. But to be honest, most of my designs start on paper, or in MS Paint. lol.

              That was all AutoCAD2000.

              Well, I am a Draftsmans 'A' by trade, in AutoCAD and manual. I also am looking to learn Solidworks, and have SW2K2 on the way. It should be here this week.

              As for that valve, that should be the simplest. Or you could even get a cocker or BM2K valve and run a Clippard 7/8 ram to it.

              I have some quick "maybe" drawings of the 'Shiva' body.

              Just some quickies, for comment. I will post those tonight.

                Can't forget about solenoids...
                Same thing, only with a solenoid. Or a small servo could do it. just have to straighten out the arm... I think Ill wok up something like that in max..
