Walschaerts valve gear

My model of Walschaerts valve gear some parts are imaginary and some are impossible to assemble, but it represents basic idea.

Special thanks to Bryan (2nd Class Steam Engineer) who provided me with some useful scans.

@robertgift I didn't want to waste anyone's time so I was aiming for the shortest version.

There is always a replay button. Unless you think it should include more details or different angles.

Thanks.

@JETZcorp the cut away video model, it does nothing. this video, it's on the arm, not direct connected so it has a gearing effect, just a little bit, lessening how far the valve gear moves

Very cool videos, thank you for sharing!

@JETZcorp This backward L shaped thing consists of combination lever (vertical part) and union link. I think it is suppose to improve timing of control valve. (and therefor efficiency). It also make the valve move a little when radius rod is set in neutral position. But I am not know for sure. Ask Google for more information.

Okay, so here's a question. What's the function of that backward-L-shaped arm thing on the far right, just to the left of the cylinder? I get what everything else does, except that.

There's a beautiful simplicity about this gear...
