(...) Looks like we did it again. I read this post, (URL) wanted to come up with a working pressure regulator. I came up with, you guessed it, a single switch piston and rubber bands. I snapped some photos, which will appear on Brickshelf soon, and (...) (19 years ago, 23-Nov-05, to lugnet.technic)

(...) I think that we can make a simple pressure regulator using a piston, a single switch, and rubber bands. The piston is mechanically linked to the switch. Rubber bands compress the piston. When the piston is most contracted, the switch is off. (...) (19 years ago, 23-Nov-05, to lugnet.technic)

Vineet, if I have been following the threads properly- the breakthrough that may allow the use of hydraulics with Lego penumatic components is the set up which takes out the implicit forth port so you dont get squirting oil from your creations. It (...) (19 years ago, 23-Nov-05, to lugnet.technic)

(...) Thank you. (...) Well we must agree that the switch solution is a bit gangly. I'd like to work on a more compact solution before I bother with the engine. When simply run on compressed air, the sequencer cycled faster than I would have (...) (19 years ago, 23-Nov-05, to lugnet.technic)

(...) Hydraulics and pneumatics are similar. Pneumatics uses air, which is a gas and can be compressed. Air pressure difference is what makes pneumatics work. Hydraulics uses fluids which compresses a little, but not much compared to gasses. Both (...) (19 years ago, 23-Nov-05, to lugnet.technic)

Kevin Clague- How can a lego pneumatic do hydraulic work? If I'm not much mistaken, hydraulics and pneumatics use two diferent sources of power. (19 years ago, 22-Nov-05, to lugnet.technic)

(...) Yes, I was wondering what method should be used to bleed them successfully. The clamp idea is a good one. My compressor is very basic. I don't have buggy motors. To build the pressure/vac engine all you would have to do, I assume, is split the (...) (19 years ago, 22-Nov-05, to lugnet.technic)
