I have a question about the gas system. What is the purpose or function of the individual check valves used on each air spring?</div>

I just sent you a Google drive link to a place that Greg was collecting this documentation. We uploaded a bunch of stuff there about a year ago.<br>
<br>
You can see:<br>
<br>
GAS SYSTEMS.pdf<br>
<br>
This should be a rough schematic of the air spring suspension system. I don't think you need the "nitrogen purge system", so just the first page of that is relevant.<br>
<br>
There are some other photos. I can ask John if he has a mechanical drawing of the little brackets that attach the dampers.<br>
