How far will the piston travel once the pilot is dumped?
and at what point of travel is the majority of the psi gone from the chamber?
I'm an idiot.... can someone please move this to the pneumatic discussion for me.

Well in a frictionless enviroment, the piston will keep going.jr wrote:How far will the piston travel once the pilot is dumped?

It will go until it is told to stop by something we like to call 'the bumper'.
For the second question, probably when the piston has travelled half way.

There are too many variables to give you an answer - it depends on how big your chamber is, how heavy and tight your piston is, what psi you're using and how good your pilot valve is.jr wrote:How far will the piston travel once the pilot is dumped?

so any time after the half-way point I can stop the piston travel? Do all those veriables realy affect the distance a piston travels and how soon it can be stopped and returned..I know that the pilot volume will have an affect on the travel speed.. and that was the next big question.

No.... You find the optimum piston travel and let the piston travel that far.
There is no 'halfway' point in a piston. EVERY PISTON IS DIFFERENT IN THEIR OWN UNIQUE WAY. NO PISTON IS THE SAME.
I suggest you do a lot more research. No offence.

For the record, your piston only needs to travel between 25 to 50% of the barrel diameter for maximum efficiency.
Here's some theory for you to contemplate
