Anyone tried to reduce vortex piston weight? If so, what was the result of it.Thank you in advance.
big steel moving cylinder with the parachute seal attached to the nose.
Just to muddy up the waters in an attempt to clarification:It seems the proper industrial term is pneumatic cylinder https://en.wikipedia.org/wiki/Pneumatic_cylinderThe piston is the part inside the cylinder that moves. I've wondered why we don't call these pneumatic pistons for which the abbreviation would be "PP"But saying " I have a PP in my gun" just doesn't sound right.
I may fish that around as well . I could be missing something on he myselfI'm just thinking weight ,. Piston weight like where and how can you really change that. A steel part to aluminum? Shorter? How many oz do you save overall?Well guess I'll go to school on piston wright.About the best I could findAs the piston is released and starts to move air before it the pellet remains static until it's inertia is broken. This happens comparatively late, around the time peak pressure is reached, near the end of it's stroke. When this happens there is a cushion of highly compressed air before the piston. Generally speaking the back of the spring is no longer in contact with the back of the chamber. Everything is sort of floating, like when you toss a ball into the air and it hangs motionless for a second before coming back down.Before the end of the potential maximum stroke of the piston it begins to move back because it' spent most of it's energy and the pellet is still moving relatively slowly holding the compressed air behind it. As the piston bounces backwards the pressure drops off dramatically as the volume of the compressed air before it expands and energy transfer to the pellet is diminished. This is to say the energy is used to push the heavy piston backwards instead of pushing the pellet forward. A heavier piston reduces this effect.My understanding is that a lighter piston/top hat would just move faster and still expend the same amount of energy (felt as recoil) but it would do it by moving faster instead of weighing more. The energy in the spring remains the same so the transfer of energy as recoil would occur. You can't loose that energy without a damping device. You can change the shape of the graph but you cant just erase it. So, pick your poison, but you will get poisoned.Moreover the piston would begin to bounce back sooner with a lighter piston as it contacts the highly compressed air behind the pellet. So, the extra energy that a heavier piston would capture would be lost, the pellet would leave the gun more slowly and lock time would increase. The ideal thing would be a mechanical catch what would stop a piston from bouncing back. It's been tried and it's impossible in the nanosecond environment inside a springer. But stopping the piston before it moves back would increase power because that energy lost as the piston move back would be transferred into the pellet, it would accelerate faster, leave quicker, and reverse recoil would be ameliorated. If someone figures a mechanical catch for pistons that'll work it could be the next quantum leap in springer tech.There is a balance between the total accelerated mass of piston, top hat, spring, swept area, caliber, barrel length, peak pressure, internal friction, and pellet weight and shape and fit, lube etc.The one area we have a lot of control over is pellet selection and that can count for a lot. In multi factorial equations like this you're not really just (e.g.) changing weight of the pellet, you're changing all of the relationships. So, you can have a lot of effect on something by switching one thing.This guy talked up the seal in a springer that may applyhttps://www.airgunshooting.co.uk/expert-advice/is-it-possible-to-prevent-or-reduce-piston-bounce-1-4870874I guess in a gas ram I guess look over E.U market has rams for there lower power rams used for there laws?Anyway I guess I'm out of my scope on this question.
...I still do not understand why the back of the gas ram can not have the seal attached and just have one moving compressed gas cylinder piston? -Y
Could you tell me what type of peepsight you have on your hatsan? I have a walther talon magnum and don't want to scope it. Is it a williams?
