He said that you could have a poppet in a Ion if you seperated it from the bolt. And like he also said, it would then be a completely different gun. Just because it's in an Ion body doesn't make it an Ion.
Whether or not it would be a completely different gun doesn't have anything to do with the description of the valve, does it? And what does "completely different gun" mean? If the bolt were separated in the first place as it is on this marker, then ostensibly you could have a hammer-driven poppet behind it and it would still be the "same" gun.
I'm not quite sure whether you are being serious here. You are here arguing the semantics of a radial seal v face seal in the context of a system/application that most think the difference irrelevent, and yet you say that disconnecting the valve from the bolt or switching between a hammer-driven poppet and pressure controlled valve doesn't ostensibly alter the function of a gun? Which is it? Surely if you change the way the internals of a gun fundementally function then you change the gun itself? To a "different" type of gun.
You wouldn't need to change anything to ensure axial location. The front of the spool on the Etha is floating, just the same as the front of the spool would be on a Mini if you changed it to a radial seal.
You don't need to because the Etha is already a spool. It has a locating stop at the back of the spool. If it were a poppet like the mini, changing to a radial seal would require changes to address seal location. If the Ego's poppet had a radial seal it would require design changes.
Sorry, you are correct. I thought you were refering to axial alignment of the spool and body. It would be very easy to create a solid stop for a modified Mini spool.
Regarding your penultimate post, the balancing/drive forces on a poppet and a spool can be made to be the same.
Can they? The sealing force on a poppet valve/occlusive seal is distinctly different from a spool/radial seal. The radial seal seals independently of the pressure acting on it; in a poppet valve that pressure makes the seal.
My comment stands. The balancing and drive forces acting on a spool and a poppet can designed to be the same. I don't think I mentioned sealing forces. Regardless, the gas pressure doesn't have to make the seal in a poppet valve. A poppet can be pressure balanced, as long as it has some closing force, such as a spring. How well it seals across a range of gas pressures will depend on the construction of the seal and seat, of course.
How about we call it a pressure controlled valve. As Betasniper said, whether it has a radial or face seal is almost irrelevent when trying to describe the operation of the mechanism. It is more to do with what actuates the seal/valve rather than the actual construction of the seal interface itself.
Well the point of distinct descriptions is to discriminate (in the scientific sense) between designs. As I noted earlier, "pressure controlled" in firing valve operation descriptions is pretty much effectively a way to say spool-controlled, so by nature the action of a pressure-controlled valve is that of a spool valve. Please note that I have acknowledged that there is a difference in marketing but this forum's stated goal is FOR the attacking of marketing distortions, and calling the Etha a poppet in any way is frankly a marketing distortion. I'm pretty sure you know full well the Etha is a spool through and through and have stated as much in other threads.
I too have stated (I think, somewhere) that I agree that technically the gas release mechanism of the Etha is a spool valve. However I struggled with my concience to openly call it a "spool valve gun". Given the general publics current understnding of how a "spool valve gun" operates I think it would be far more misleading, to the consumer, to call this a "spool valve gun". Doing so, to me at least, would have been a far greater "marketing distortion" as viewed by the consumer than what we came up with. I have openly said that we didn't know what to call this gun. I still don;t think it should be refered to as simply a "sppol valve" gun. In my "marketing" description there is reference to a spool. We also wanted to imply that this isn't a traditional "spool valve marker" and that the spools throw was short, hence the poppet reference. And around the circle we go......
