How do you make your compressorless system work, when all valves "bleed" air slowly?

Because of the leaks there isn't really a good way of knowing beforehand if it will work. You will just have to finish the pnuematics, clean them up to be as efficiant as possible and test it.

Yea we're at that stage now. I'm sure this is NOT a dirt or bad assembly problem. I've proved that those piloted valves definitely consume a bit of air in normal idling operation.

If you tie all the outputs together, and vent this when you vent the individual cylinders, this may solve your problem.

I hope this helps...

Hi Mike!

That sounds promising. What was the part number (and cost) for the Rexroth valve you used?



I'm STILL curious though: Up to now, has everyone really just "topped it off and prayed that they'd start the round soon" whenever they ran compressor-less??? I find that hard to believe.
