Nico71's Lego Single-Cylinder Pneumatic Engine (LPE-1)

[DLuders]

On his website, Nico71 (Nicolas Lespour) posted high-resolution PDF Building Instructions for his Lego Single-Cylinder Pneumatic Engine (LPE-1). You can see more on his Brickshelf gallery, and on this

, where it displays the "Crankshaft and connectig rod, symetric rods as parallel slides with classic switching system. Work up to 200rpm on the flywheel. Very simple and functional...."

Neat! Looks like it runs very well!

[RohanBeckett]

very cool...

but I can't say I've ever seen a parts list ....broken down as much as what you've listed...

pneumatic valves and cylinders listed as individual sub-pieces!!!

I lack some of the important parts so I can't test it for myself. But my gut feeling tells me it doesn't produce much torque. True?

That's what you get when you export a parts list from LDView based on the CAD file. The CAD file has them as individual parts so you can adjust the length to make everything line up. You have to fix the parts list manually to get the complete assemblies.
