Scene tag

My rather basic hydraulic circuit. Features a realistic gear pump, pilot operated relief valve and a single acting cylinder.

The pump is controlled with Q and W, the control valve is controlled using up and down on the arrow keys.

The pump has a little bit of leakage, but the control valve and piston both feature seals that stop most internal leakage:)

Runs ok at 100Hz, but you will need a powerful computer for it to run smoothly, enjoy:)

Excellent demo of a hydraulic system! My only comment about its operation is, the pilot operated check valve doesn't seem to work. first off, I assume that the rectangular sliding block with two springs is the check (or relief) valve. Am I correct? If so, it doesn't seem to move under any condition, even when the cylinder is at maximum extension.

Maybe your next scene could be a hydraulic system with a double acting cylinder!

Oh, and welcome to Algobox! I see that you registered in 2010, but this is your first uploaded scene.

Nice job! :tup:

Thank you:) If you pump the fluid back into the reservoir with W, zoom in on the valve, then run the pump normally, you can see the point where the valve cracks open, it just doesn't open very far:P

It opens a lot further if you keep adding fluid to stop the pump cavitating, but then the scene runs very slowly, or at least slower than it already does.
Nice job :tup: :tup:
Incompressible fluids my Butt <_<
This is the main reason I havnt tried to do
any hydraulics in algodoo :bonk:
Even if you make the density of all the other components very high
the fluids still mash into and leak thru thin walls :bonk: :bonk:
Thousands of little balls works somewhat better but with similar lag problems:mad:
I agree with you Gent. Sometimes increasing the Sim Frequency helps with water and other objects leaking through walls. But of course you can't make the frequency too high because the lag will increase proportionately. Most physics simulation programs rely on really high-end computers for a true-to-life simulation, but, unfortunately, most people do not have really high-end computers.

@goof245 - I tried what you suggested, and yes, I can now see the pressure relief valve open when it should. :tup:
