(...) To be honest, I never actually intended it to be used in an engine. And to be more truthful, I just buitl my first pneumatic engine a couple of days ago, so my knowledge on the subject is a bit, archaic. I wanted to create a closed circuit (...) (19 years ago, 21-Nov-05, to lugnet.technic)

I think most certainly a combined fluidics would be in order first. Im surprised there was not already a .pneumatics, as it would seem like an obvious group. Not that I have contributed, but I do follow the pneumatics thread with great interest. I (...) (19 years ago, 21-Nov-05, to lugnet.technic)

(...) Nice work. With the exhaust sealed off, I figure the piston will move up and down gradually and gracefully rather than the quick movement that we're used too, because of the cushioning effect. This would be fine for an application like a (...) (19 years ago, 21-Nov-05, to lugnet.technic)

(...) No - exhaust! (...) You need to eventually discharge the compressed air (or vacuum) in a pneumatic system. Interestingly enough, this is the first time I heard of a pneumatic system using compressed air and vacuum at the same time. Usually (...) (19 years ago, 21-Nov-05, to lugnet.technic)

(...) Here we go. I finally got some pictures of my progress. (URL) The tank represents the load on the circuit. (URL) And this is with the ram for the load. I am very pleased to find that it works. (URL) Its interesting to me too. Rather odd that (...) (19 years ago, 21-Nov-05, to lugnet.technic)

(...) Andrew, It is so interesting that you broached the topic of vaacume/pressure pressure at the same time as the hydraulic question. In many ways they are the same problem. Containment. With vaccume/pressure you need a switch with containable (...) (19 years ago, 21-Nov-05, to lugnet.technic, FTX)

(...) That IS odd! And thank you for the reassurance. I have just completed attaching a load to the pump. Basically I just copied my pump and used it as my load. Using the pupm and alternating the valves and strokes, the load ram moved outward as (...) (19 years ago, 21-Nov-05, to lugnet.technic)
