Re: Constant Force Pneumatics?
Yes,
What you do, is use a "Precision Air Regulator"... this is like other air pressure regulators, except... it will maintain an exact setting. So you want 20lbs of pressure. If the pressure is higher, it will release some air, and if the pressure drops, it will add some air. You always have exactly 20 lb's of pressure. the regulator handles it all for you. As well, with the regulator, it is easy to adjust.
Warning: They are not cheap... maybe around $100.00 for a small one.
