well, I understand all this, re current LEGO valves with air tank yeilds an "on or off" action with the cylinders. My concept was if we could build ( out of LEGO) a better way of metering the air flow. Mechanical stops would be one way of limiting (...) (25 years ago, 20-Sep-99, to lugnet.build)

I don't agree. Considering last year, it is maybe, but I can't call it extraordinarily good. Just look at the sets available in 1995,1996 and even 1997, so you might see my point. 1995: 8812 Aero Hawk I ( helicopter) 8816 Off Road Rambler (small (...) (25 years ago, 20-Sep-99, to lugnet.build)

(...) Sure, but in the original configuration of 8868, you have more control, as you can turn the compressor on and off for short durations and yield relatively small changes in the stroke of the cylinder. Adding an air tank really makes this much (...) (25 years ago, 20-Sep-99, to lugnet.build)

Hydraulic and pneumatic systems work differently. In the first one, your working fluid is an incompressible one (liquid oil, generally) so you have the full control of the stroke length of any piston.But in the case of pneumatics, the working fluid (...) (25 years ago, 20-Sep-99, to lugnet.build)

(...) Hi Fredrik, That lack of control of the cylinders has been my experience too. You really have to barely open the valve to be able to stop in partially extended movement. I wonder if you designed a cam that would squish the tubing past the (...) (25 years ago, 19-Sep-99, to lugnet.build)
