Im not sure if this is the correct forum for this question if not let me know and Ill post it to the right one. Anyway I need to creat a small scale pneumatic oscillating cylinder, I have a couple ideas but could use the help of someone witha background or knowledge in pneumatics. I need the cylinder to have a adjustable throw length and hopefully have a adjustable throw strength. I have seen similar systems where a fan driven device is used with a cam connected to the center drive, the cam giving it a oscillating output, and the amont of air controlling the speed. but Im trying to use a cylinder system. I know there is a difference in air pressure and speed but Im not sure how what does what, Is it better to control air pressure on this type of setup or to control air speed. I really need this system to be as simple as possible due to fabrication costs. If you want to email me directly firstname.lastname@example.org I can send you some images of what Ive bben working on so far and tell me if it will work.
