Compressor timing varies with the amount of pressure in the tank
I agree with your assessment when working with check valves. But think of an industrial scroll compressor. That type of compressor has no valves.
In my proposed design, each cylinder inlet stroke takes in .31 cu-in of air which equals .0021 moles. Those .0021 moles are then pushed into the air tank. Prior to opening the cylinder to atmosphere again, the cylinder is isolated from the tank through the radial valving.
I guess I just don't see the difference other than the elimination of the check valves. But I will lose some pumping efficiency due to the inevitable leakage between the high and low pressure air channels. For this project, I'm willing to lose some efficiency for a quiet air compressor.
I need to take another look at my numbers though. I'm not sure I got the massflow correct.
