Had to take some artistic licenses, but it worked out in the end...

It's difficult to show exactly what happens to the pressures at every step during the piston movement but I think this conveys the jist of it. (even harder when trying to make the demonstration loop continuously)
The colors are a little wonky but what else is new. I've found it's always hard finding a good pallette of colors that mix well together while still leaving enough shades to differentiate everything. a graphic designer I'm not....

The only thing that's up in the air (har har har) is the release spring mechanism. I originally thought the spring was actuated merely by the cam hitting a sweet spot where it was aligned with the release lever, reducing the force being transmitted to the lever......but then as I was gazing at the finished animation I realized the thing would never really turn off if the cam position was the only factor. So I see now that the direct pressures in the pistons equalizes it more than I originally assumed...I couldn't visualize that as well as I thought before I made the animation, so I didn't really "plan" to express it. But I think it can still be explained by watching the simplified pressure changes.
I might be able to fix that but it'll take a lot of busywork (nooooo)

That is all :cool:

WOW! FANTASTIC job! Can I use it for the website?? Of course I will give you credit.

Thanks!

Thanks for sharing. This answered a lot of questions in a few minutes that would be hard to explain. Ben

That is nice, but it does not work. I've been running it for a hour and my computer has not has not increased a single PSI.

Must be your bleed valve knob :)

I went ahead and updated the GIF files by rearranging the text, making the watermark less intrusive, got rid of the "legend" etc. I think it's better now.

Tom you can certainly use it for anything! I already watermarked it so you don't really have to bother mentioning credit.
I can change it later to reflect any changes should you make them, just have to let me know.

Careful some unscrupulous sort doesn't pillage your idea.
